He first ran for parliament in 1910, contesting the
East Province of the
Legislative Council in a
by-election on 26 September resulting from the death of
George Throssell. Colebatch came second out of the three candidates, being beat by the more well known
Warren Marwick. He then received a petition from 72 electors to run again, so he contested the newly-created
seat of Avon in the
1911 state election. He was narrowly defeated by
Thomas Bath from the Labor Party. In early 1912, Colebatch and Mitchell formed a Liberal League in Northam. Colebatch was also the convenor of a finance sub-committee within the Liberal Party, which made the successful recommendation to charge a membership fee so the party would be less reliant on large donors. In March 1912, Colebatch was elected to the executive committee of the Liberal Party. Colebatch was initially not going to contest the
May 1912 Legislative Council election, but Marwick had become unpopular in Northam due to his opinion on the proposed route for the
transcontinental railway line. The most likely route was to be via
Midland and Northam, where there was already a line, but there was an alternative proposal via
Armadale and
Brookton, which is also in the East Province. Marwick chose to support the Armadale-Brookton route, which resulted in his unpopularity within Northam. A public meeting in Northam decided that a better candidate must contest the East Province, and so Colebatch became a last-minute candidate. He supported the transcontinental railway line passing through Northam and a developmental railway being built from Armadale to Brookton. Colebatch won the East Province, beating Marwick by a small margin in every polling place except for in Marwick's home town of York. Colebatch took his seat on 27 June 1912. He did not contest the November 1912 Northam municipal election and was succeeded as mayor by Bernard.
In opposition Colebatch was part of the newly-formed
Liberal Party, however in his
maiden speech, he said he would always speak for his individual feelings. At the time,
John Scaddan had been
premier for a year and the Labor Party had a substantial majority in the Legislative Assembly, however the Legislative Council had a conservative majority. According to historian
Brian De Garis, "for a man like Colebatch, there could not have been a more opportune moment for launching a parliamentary career". He says it would have been difficult for Colebatch to stand out if he had entered the conservative-dominated upper house during a Liberal government, but entering during a Labor government gave him an opportunity to use his formidable debating skills. Colebatch would soon become the Scaddan government's harshest critic in the Legislative Council and Labor members grew to dread his speeches. The Scaddan government felt that establishing and expanding government enterprises was in the best interests of the state, something that Colebatch was strongly opposed to. The government set out to establish state-run and state-subsidised brickworks, sawmills, quarries, hotels, dairies, ferries, butcher shops, fish shops, brick works, tramways, meat works, quarries and abattoirs. Colebatch lead the opposition to the Tramways Purchase Bill 1912, which sought to nationalise
trams in Perth. He felt that the
Perth City Council was being cheated out of their reversionary rights to the tramways and that the government would be a poor operator like they were with the railways. The bill was passed anyway, but it earned Colebatch a reputation as a "hard fighter and a brilliant speaker". Two of the most important bills passed in this session of parliament were the Workers' Compensation Act and the Industrial Arbitration Act. Workers' Compensation previously only applied to certain occupations, but the new act extended it to apply to all workers earning less than £300 per annum. Although he did not vote against it, Colebatch criticised the bill for hurting employers and was successful in limiting parts of the bill. The Industrial Arbitration Act consolidated previous legislation and made it easier for unions to approach the
Court of Arbitration. Colebatch opposed the bill for preferencing unionists and hampering the ability of industries to compete with overseas firms. Eventually the two sides met and worked out a compromise which the government and the opposition could both support. One bill that Colebatch was especially interested in was the Water Rights and Irrigation Bill. The bill was referred to a
select committee that he was the chairman of and he introduced many of the amendments that the committee recommended. The amendments were not accepted by the Legislative Assembly though and the bill did not pass. The following year, the bill was introduced again, but it failed to pass again. It eventually passed in 1914. By 1913, Colebatch had gained a prominent position in the Liberal Party's governance. In February 1913, he was elected as a vice-president of the party's executive committee. His opponents used this to attack his claimed position of being above party politics. One of the bills the government introduced in 1913 was the Electoral Districts Bill, which proposed having commissioners design the electoral districts rather than parliament and introduced equally-populated constituencies for all of Western Australia except for three seats in the north of the state. This would have increased the number of metropolitan districts at the expense of rural districts. Colebatch opposed having equally-populated constituencies, saying that "it seems to be utterly unfair that huge districts with great interests and scattered population should be put in the same position as closely congested and settled communities". He proposed seven amendments, including that rural districts should have 20 percent fewer voters and metropolitan districts should have more voters. The Legislative Council accepted these amendments but the Legislative Assembly did not, meaning the bill was unable to pass.
Matthew Moss, the unofficial leader of the opposition in the Legislative Council, retired at the 1914 election, enabling Colebatch to take the position. During 1914, Colebatch lead the opposition to the Income Tax (War Emergency) Bill, which was to raise taxes mainly to support farmers during the drought which was occurring at the time. Colebatch attacked the government for introducing the bill so late in the session, just before the
1914 election, without the presentation of estimates, and for only one third of the money raised going to the farmers. The bill was defeated by the Legislative Council by eighteen votes to six. The following year, Colebatch opposed the Income and Public Entertainments Taxation Bill, which was expected to increase taxation so that money could be spent on public works to create jobs. He believed that the money would better off with private enterprise, which would be able to provide more jobs and greater benefits to the state.
In government In July 1916, the Liberal and
Country parties cooperated to pass a
vote of no confidence in the Scaddan Government. Labor had been left with a minority of seats in the Legislative Assembly following several resignations and the Country Party had drifted closer to the Liberal Party compared to when they were initially elected to parliament in 1914. The Liberal Party's
Frank Wilson became premier, and although he had only been in parliament for four years, Colebatch was an obvious choice to join
the ministry and lead the government in the Legislative Council. By this time, Colebatch was looked at by some as the state's next John Forrest, and so he was appointed
Minister for Education and
Colonial Secretary. Mitchell was also a member of the ministry, being appointed
Minister for Railways and
Minister for Water Supply. The colonial secretary was responsible for numerous miscellaneous departments, including charities, public health, aborigines, public gardens, the state shipping service. Although the colonial secretary had to introduce many bills and answer many questions in parliament, it was not a role that allowed for high achievement to shine. On the other hand, the role of education minister allowed for this, and Colebatch found this to be his favourite portfolio. He later claimed that he was appointed education minister due to his advocacy for country high schools when Wilson was previously premier. Parliament was adjourned for seven weeks for
ministerial by-elections to take place. Colebatch was subsequently elected unopposed. Soon after parliament resumed, it was adjourned again for the
1916 Australian conscription referendum campaign. Like most Liberal politicians, Colebatch supported
conscription, and his rhetoric grew more and more nationalistic as the campaign went on. Western Australia ended up voting for conscription, whereas nationally, the majority voted against conscription. Meanwhile, both of Colebatch's sons enlisted in the army and in 1917, they went to fight in France in
World War I. Gordon was severely injured by a shell blast and suffered the effects of this for the rest of his life. To help raise funds for soldiers and dependents in need, Colebatch was the chairman of the Western Australian War Patriotic Fund. The parliamentary session under the Wilson government only got underway in November 1916. The government passed the Trading Concerns Act, which put all trading concerns on a commercial basis as well as preventing the establishment of trading concerns without the approval of parliament, preventing the government from using its executive power to do so like the Scaddan government often did. The State Fish Supplies, which was one of Colebatch's responsibilities, was shut down due to not being commercially viable. On the other hand, the State Steamship Service proved viable and was not shut down. Colebatch was opposed to large-scale gambling and lotteries, particularly those run by the government, believing them to be a tax on the poor and stupid. He introduced a bill to outlaw
bookmaking in 1916, but it was not passed by parliament. A success that Colebatch had as colonial secretary was to convert
Rottnest Island from a prison to a holiday resort. The island was made an
A-class reserve in 1917 and Colebatch was appointed as the first president of the Rottnest Island Board of Control. Some prisoners were retained for the first few years as cheap labour, but by 1922, the last prisoners were removed from the island. In May 1917, the Liberal Party was disbanded and turned into the
Nationalist Party, and in June, the new party elected
Henry Lefroy as its leader. Wilson resigned as premier, and so Lefroy was appointed to the position. Colebatch became the unofficial
deputy premier and kept his previous positions in the
new ministry. Despite this, Colebatch stated his distaste in the way that Wilson had been ousted and was disappointed that Mitchell was no longer in the ministry. The
1917 state election occurred soon after the
Lefroy Ministry was appointed, and after that, parliament only resumed for a week before it was adjourned for the
1917 Australian conscription referendum campaign. By 1917, Colebatch had established district high schools in Northam and
Geraldton. He had also established scholarships to enable children from outside areas to attend them. Two more district high schools were created in
Bunbury and
Albany that year. Establishing the first high schools outside Perth and the Goldfields had been the issue which had impelled him to enter politics. In 1918, Nationalist member
John Stewart resigned from the
seat of Claremont in the Legislative Assembly. It was offered to Colebatch that he resign from the Legislative Council to contest the
resulting by-election so that he could one day become premier, however Colebatch decline the offer as he did not want to undermine confidence in the Lefroy Government.
Spanish flu By late 1918, the
Spanish flu had become a pandemic, and returning soldiers aboard the
HMAT Boonah were falling sick. As the Colonial Secretary, Colebatch was responsible for public health. With the ship approaching Fremantle, Colebatch set up an emergency isolation camp on
Garden Island to supplement the existing quarantine facility at
Woodman Point. He also considered using Rottnest Island if need be, but it was not ideal as it was further from the mainland than Garden Island. The
mayor of Fremantle, William Montgomery, demanded that Lefroy disallow the
Boonah from entering the port. However Colebatch stated that he believed that the sick soldiers were "entitled to be taken off the boat as soon as land is reached", and that allowing the ship to continue on to the
eastern states would result in most of the other passengers on board being infected. As a result, several hundred of the 1,200 people aboard the ship were quarantined at Woodman Point. Colebatch denounced the federal government's handling of the matter, as despite it being responsible for shipping and quarantine under the
Australian constitution, it did very little. The state and federal governments agreed that any state with a Spanish flu outbreak should be declared an infected area, which would stop all land communication and sea communication would be quarantined. Following Parliament's recess for Christmas 1918, Lefroy and two cabinet ministers attended conferences in
Melbourne, leaving Colebatch as acting premier. During that time, the Spanish flu broke out in South Australia and
Victoria, however these states refused to follow the agreement and did not declare an infected area. Despite this, Colebatch decided to close the Western Australian border. Coincidentally, a shipping strike meant that there was no coastal shipping in the state, but transcontinental trains were still running when he decided to close the border. Passengers on a train from Adelaide were put in an improvised quarantine camp in
Parkeston just east of Kalgoorlie where the railway gauge changed.
William Watt, the acting
prime minister, threatened Western Australia with dire consequences for impounding the train. Watt told Lefroy that: Lefroy decided that he would not stand in the way of Colebatch and further action was up to him. South Australia eventually declared infection meaning the railway would have been shut down under the agreement. Because of the shipping strike, Lefroy and the two ministers could not get back to Western Australia without taking the train. Colebatch decided to allow a special train in, as long as the people aboard quarantined, but Watt disallowed this from happening. In general, Western Australians strongly supported Colebatch's actions during the Spanish flu pandemic. He earned further praise when he ended a two-month-long tramway strike.
Premier In April 1919, Lefroy resigned as premier, and Colebatch took over, becoming the only premier to come from the Legislative Council. Colebatch made himself
Colonial Treasurer, the
minister for education and the
minister for railways. He reinstated Mitchell in the cabinet, making him the
minister for lands. The largest issue during his premiership was the
1919 Fremantle Wharf riot. Stevedores from two different
unions — the National Waterside Workers Union (NWWU) and the
Fremantle Lumpers Union (FLU) — were working at
Fremantle Harbour. The two unions often disagreed with each other and the
Commonwealth Arbitration Board favoured the NWWU. Western Australia had a shortage of many essential goods such as medical supplies and food as a result of the earlier shipping strike and the need to quarantine. When the SS
Dimboola arrived in Perth from Melbourne, carrying passengers (including Lefroy) and cargo, the passengers and most of the crew went into quarantine, but the federal government allowed some of the crew to berth the ship before going into quarantine. Fremantle Harbour officials did not allow the ship to berth and forced it to be fumigated at anchor. The NWWU workers then began to unload the ship but the FLU workers attacked them and started
picketing, wanting to remove all NWWU workers from working at the wharf. Colebatch implored Watt to try and settle the dispute, as industrial relations were the responsibility of the federal government and the state had little power to do anything other than to use police to diffuse violence. Watt disagreed and said it was up to the state to solve the issue. He also said that if the issue was not fixed quickly, then he would stop shipping to Fremantle. His son,
Hal G. P. Colebatch, posited in his 2004 biography that Watt was "probably trying to get revenge on Colebatch for impounding the Commonwealth train and his earlier criticism of the Commonwealth Government during the
Boonah affair." On 1 May, Colebatch told the FLU that he would get the police if they did not come to an agreement or cease picketing the wharf. The union did not do this, and so on 4 May, a group of people travelled down the
Swan River in two
launches. Among the people on the boats were Colebatch, the
commissioner of police, small businessmen and consignees desperate to get the
Dimboola unloaded. As the boats travelled under a bridge, the FLU members dropped rocks, scrap iron and other objects onto the boats in an attempt to sink them. The larger objects missed the boats, but several people were injured by smaller objects.
University of New South Wales Professor of History Francis Keble Crowley said that "the premier came close to being assassinated when masonry hit the deck of his launch." When the boats reached the wharf, a riot broke out between the union workers and the police, who were trying to push the crowd back from the ship. During this, a man named Thomas Edwards was injured and later died. The police commissioner told Colebatch that the police could not control the situation without shooting their guns, but Colebatch did not want to authorise that. Colebatch, the police commissioner, the businessmen and consignees soon left, unsuccessful. In total, approximately 26 police officers and six FLU workers were injured, excluding Edwards. The following day, there was further violence between police and union members. Colebatch announced on 8 May 1919 that the NWWU had agreed to withdraw from the wharf to avoid any further conflict. Colebatch resigned as premier on 15 May 1919 as he was unable to find a Legislative Assembly seat and his health was deteriorating due to undiagnosed diabetes. On 17 May,
James Mitchell was sworn in as premier and Colebatch was appointed the
minister for agriculture, minister for education,
minister for the north-west and the new position of
minister for health, a role which he had performed before that as the colonial secretary. He was also the deputy premier and leader of the government in the Legislative Council again.
Mitchell Government Mitchell did not like travelling interstate for meetings with the prime minister and other premiers, so he often had Colebatch represent him instead. Colebatch attended a meeting with Prime Minister
Billy Hughes and the other premiers in October 1919. Hughes wanted to enlarge the powers of the Commonwealth Government, which Colebatch was opposed to, as he believed local self-governance improved economic efficiency and individual freedom. Starting in May 1920, he visited the north-west of the state, a place usually neglected by the state government. When he visited
Onslow, it was the first time in ten years a government minister had visited there. The visit to the north-west lasted three months and he travelled . He met with Hughes again to show the prime minister the
Group Settlement Scheme and the
Fairbridge Farm School. Colebatch managed to help convince Hughes of the need for an increase in immigration to increase the state's population and develop its infrastructure, an interest of Mitchell's. Hughes wrote a letter to Colebatch in March 1922 committing to increasing immigration, and later an agreement was signed between the Australian, Western Australian and British governments for seventy-five thousand British migrants to settle in the state. Reducing unemployment was one of Colebatch's other responsibilities, and he instituted various public works to help with that. Although some saw trying to increase immigration as working against efforts to decrease unemployment, Colebatch believed it would be short-sighted to not do so. In addition to showing Hughes around Western Australia, Colebatch did the same for several other figures. In 1922, he guided Colonel
S. F. Newcombe, who was sent by the British Government to investigate settling discharged soldiers there. He also guided
V. S. Srinivasa Sastri, who was sent to ensure that Indians settled in white British countries were not discriminated against. Another task for Colebatch was to negotiate with John Forrest's widow,
Margaret Forrest, over a statue of Forrest which the government wanted to erect in
Kings Park. Lady Forrest wanted for the statue to depict him as a "slim young explorer", but Colebatch convinced her that a statue depicting him as a "mature and portly statesman" would be best. From 1921 to 1922, Colebatch was the president of the
West Australian Club. He was also a life member of the
Royal Perth Yacht Club. Following the
1921 state election, Colebatch was the only minister in the Legislative Council. He was therefore responsible for introducing and handling all bills and other business of the upper house, placing a large workload on him. As there was much hinging on him, the house adjourned when he became sick. Several of his colleagues thought the burden on him was too much. In the
1923 New Year Honours, Colebatch was made a
Companion of the Order of St Michael and St George. Later that year, his title of "Honourable" was made permanent. In early 1923, Mitchell announced that he had chosen Colebatch to be the next
Agent-General for Western Australia in
London. He resigned from the ministry and from parliament on 17 June 1923, and was succeeded by
William Carroll. Over the seven years he had been a minister, the state's expenditure on education had risen by 73%. To show their admiration, senior
Education Department officials arranged a special function for Colebatch's departure. He had given equal shares in
The Northam Advertiser to his wife and two sons as a reward for their service in the army. Harley became editor though Hal continued to write for it. ==Agent-general==
