In 1838 the Goulds sailed to Australia, intending to study the birds of that country and be the first to produce a major work on the subject. They took with them the collector John Gilbert. They arrived in Tasmania in September, making the acquaintance of the governor Sir John Franklin and his wife. Gould and Gilbert collected on the island. In February 1839 Gould sailed to Sydney, leaving his pregnant wife with the Franklins. He travelled to his brother-in-law's station at Yarrundi, spending his time searching for bowerbirds in the Liverpool Range. In April he returned to Tasmania for the birth of his son. In May he sailed to Adelaide to meet Charles Sturt, who was preparing to lead an expedition to the Murray River. Gould collected in the Mount Lofty range, the Murray Scrubs and Kangaroo Island, returning again to Hobart in July. He then travelled with his wife to Yarrundi. They returned home to England in May 1840.
