Despite these distinguished connections the family was not well-heeled. Young George O'Brien may have been trained by a brother as a civil engineer. His parents died when he was young and it seems that by a very early age he was in Melbourne, Australia. Views of the town dated 1839 and 1840 survive in the collection of the state library. It seems he left soon afterwards but was back by 1850 arriving from London on the Midlothian. He worked as a draughtsman in the surveyor's office and in 1853 married Jane Mashford at St. James' church Melbourne. He was active in the Victoria Fine Arts Society and by 1854 was advertising his services as an architect and surveyor. He exhibited paintings in 1856 and 1858 and nine signed and dated watercolours of St. Kilda and nearby places in Melbourne are recorded.
