Here he remained two years, collecting in the vicinity of Rio, the Organ Mountains, San Paolo, and other parts of Brazil.

Sir Joseph Banks wrote that his collections, especially of orchids, bromeliads, and bulbs, "did credit to the expedition and honour to the Royal Gardens." He was nominated for service in New South Wales, and landed at Port Jackson on the 21st of December, 1816.* He first started collecting about the present suburb of Woolloomooloo in Sydney, which we may infer therefrom presented a very different appearance from that which it now presents.

He next went with Oxley on his Lachlan expedition.

On his return, he commenced the first of his five coastal voyages, in which he accompanied Captain P.P.King around most of the continent of Australia.

In the tiny cutter the Mermaid, of 84 tons, they left Port Jackson on the 22nd of December, 1817, and sailed round the south coast of Australia to King George's Sound, the west coast, the north coast, and finally to Timor.
The Mermaid returned by the same route and anchored in Port Jackson on the 24th of July, 1818.
