He sailed on the frigate to Tenerife, China and the East Indies, before returning to Europe to study botany, mineralogy and chemistry. In 1824 he was a surgeon on board and travelled to Africa, Brazil, Chile, the Sandwich Islands, California, Kamchatka Peninsula, Taiwan and Mexico. Collie was ship's surgeon on. This was part of the expeditionary group, including the barqueParmelia, which set out from Portsmouth in February 1829 to found the colony of Western Australia. While at sea on 16 April 1829 Collie assisted with the birth of Frederick Henry Stirling, the son of Lieutenant-GovernorJames Stirling and his wife Ellen. They arrived at Rottnest Island on 3 June 1829, upon which Collie started working in a hospital tent on Garden Island. He studied botany in his free time. He received of land on the banks of the Swan River. He and a Lieutenant Preston explored the south west of Western Australia, discovering two rivers that Lieutenant-Governor Stirling named after them: Collie River and Preston River. In 1830 he investigated the conditions on the Peel estate. He reported that the estate's manager, Thomas Peel, was incompetent, which led to government assistance for the settlers. In 1831, Collie was allotted of land in Albany, where he was appointed a Justice of the Peace and became the town's first government resident. Suffering from ill health he returned to Perth and was appointed the Swan River Colony's Colonial Surgeon from 1833 to 1835. His decision to return to England was made too late; although he had embarked on HMS Zebra, he died before the ship left Western Australian waters. He died in King George Sound on 8 November 1835 and was buried beside Mokare, his Aboriginal exploring companion. The graves of both Collie and Mokare were disturbed during the construction of the Albany Town Hall in 1887. Collie's remains were interred at Pioneer Cemetery in Albany.
