Wonuarra is a locality south-east of Paringa at the eastern end of the South Australian Riverland region.

[2] Wonuarra was on the former Barmera railway line of the South Australian Railways; the Wonuarra siding was the first siding south of Paringa, from where the main commodity dispatched was bagged wheat.

[3] The siding was originally named Koora, but renamed to Wonuarra because the original name was easily confused with Noora, further south.

[note 1] It was 27.3 kilometres (17.0 mi) long, and went north-east to Murtho to the south bank of the River Murray.
