[1] It is on the inside of a bend of the Murray River downstream from Waikerie, and the only land border is the main road from Waikerie to Cadell, with Sunlands on the other side of the road.

Land use in Qualco is predominantly irrigated vineyards and orchards, along with some cereal crops.

The river is bounded by wide flats that flood during periods of high flow.
