Wilcannia was an electoral district of the Legislative Assembly in the Australian state of New South Wales from 1889 to 1904.
The population in Wentworth had grown significantly since the 1880 redistribution, especially as a result of the growth of mining at Broken Hill.
Because of the large area covered by the district, in 1889 it was split into 3, Wentworth, Sturt and Wilcannia.
[2] It was abolished in 1904 due to the re-distribution of electorates following the 1903 New South Wales referendum, which required the number of members of the Legislative Assembly to be reduced from 125 to 90.
[4][5] The member for Wilcannia was Richard Sleath (Independent Labour) who unsuccessfully contested the 1904 election for The Darling.
