Tinline was born near
Jedburgh, Scotland in 1815. His parents Esther (born Easton) and John were poor. In 1860 the manager Stephens left for England, and George Tinline was appointed acting manager. This was the time of the gold rush, and the Colony was beset with, apart from the shortage of workers, a financial crisis due to the sudden increase in the availability of gold and the lack of sufficient currency to pay for it. He pushed for the establishment of an
assay office and
mint, and the conversion of some of the diggers' gold to bullion which could be used as a form of currency. A Bullion Act was passed and some 25,000
£1 coins were minted, but were not recognized as legal currency by the Bank of England. In recognition of his work in staving off a crisis Tinline was awarded a purse of 2,000 guineas (£2,200; several millions of dollars in today's money), and an elaborate silver salver (now in the
Art Gallery of South Australia), He was sacked by the bank in 1859 after severe losses caused by a customer defaulting, and joined his brother in law
A. B. Murray in developing a pastoral lease at
Wirrabara. He was one of the Lands Commissioners when he was elected in April 1860 to fill one of two vacancies in the
Legislative Council, then created a vacancy when he abruptly retired to England in May 1863. The house which he had commissioned near the summit of
Mount Lofty was sold, half completed, later to become
Stawell School for Girls. He paid a short visit to Adelaide in 1894 or 1895, and was in
Melbourne when he died. ==Other interests==
