Grantala left
Southampton on her delivery voyage from England to Australia. She sailed via
Cape Town and
Durban, and reached
Fremantle on 29 February. She continued via
Adelaide and
Melbourne, and reached
Sydney on 10 March, carrying about 200 passengers from England and South Africa. She then immediately joined her sister
Yongala on the Adelaide Steamship Co's interstate route between Sydney and Fremantle. From 1908 until 1914,
Grantalas route alternated seasonally. For part of the year she ran between Melbourne and
Cooktown, Queensland, and the for remainder she worked her original route between Sydney and Fremantle. By 1911
Grantala was equipped for
wireless telegraphy, and by 1914 her
call sign was VHJ. colours off
Suva,
Fiji in November 1914 On 4 August 1914 the UK entered the
First World War, and three days later the RAN requisitioned
Grantala. She was fitted out at
Cockatoo Island Dockyard and
Garden Island Naval Base as a hospital ship, with capacity for up to 300 patients, and 59 medical and nursing staff. The conversion was completed in 17 days. She was Australia's only hospital ship in the First World War. On 30 August
Grantala left Sydney to support the
Australian Naval and Military Expeditionary Force landing at
Rabaul in
German New Guinea. She was later recognised with the
battle honour "
Rabaul 1914". However,
Grantala proved too small for the purpose for which she had been requisitioned, so the RAN returned her to her owners at Sydney on 22 December. ==Red Funnel and CGT service==
