Culgoa National Park.

The Culgoa River flows in a south-westerly direction, in the east of the degree square. It eventually joins the Barwon near Bourke (NSW), forming the Darling River.

National Parks extend north and south from the degree confluence into Qld and NSW. On the Queensland side the Culgoa Floodplain NP is about 42,800ha. It is rich in aboriginal heritage, grazing history and wildlife.

Border Fence, Brenda Crossing

Brenda Crossing (Gate) connects Goodooga (NSW) and various properties in Qld. The border fence here is quite modest (shown heading eastwards into the distance). Landuse practices are shown to make a difference - left (north) of the fence is in Qld, the right side (south) is in NSW.

Brenda Station has a long history.
