Charles Throsby (1777 – 2 April 1828) was an English surgeon who, after he migrated to New South Wales in 1802, became an explorer, pioneer and parliamentarian.
They departed Portsmouth 12 February 1802,[1] and arrived in Sydney without calling in port on 13 June 1802, with no reported convict deaths under his care.
[5][6] He was put in charge of the construction of a road to the Goulburn plains and in August of that year two of his men reached Lake George.
The details of this trip are lost, but it is probable that Throsby passed through what is now the Australian Capital Territory and that he reached the Yass River.
On 20 March 1821 Throsby with two companions made an expedition to reach the Murrumbidgee River, having heard of its existence from Aboriginal people.
Coming first to the Molonglo River he probably discovered the Murrumbidgee below Tuggeranong, near Pine Island early in April 1821.
In about 1811 Throsby had become security for the purchase of a vessel by a friend, Garnham Blaxcell, who had left the colony in 1817 and subsequently died.
