John Matthew Richardson (28 April 1797 – 28 July 1882) was an Australian convict who accompanied several exploring expeditions as a botanical collector.
By 1821 he had earned a full pardon, and that year he was sent back to England in charge of a collection of plants and seeds.
Hall (1984) states that he was a member of John Oxley's expeditions of 1823 and 1824; but Short (1990) considers this merely a possibility, despite quoting a statement by Thomas Mitchell asserting that he did, and noting that Richardson provided seed from the Port Macquarie region to an English nursery before 1825.
[3][4] In February 1826, Richardson, by then married, was sent to take change of the garden of a new settlement at Fort Dundas on Melville Island.
He was assigned to a settler at Cooks River, until he was sent to work on an Iron Gang on Mount Gibraltar near Bowral in 1834.
