Sunlands is a locality on the left bank of the Murray River, ten kilometres west of Waikerie, South Australia. The Waikerie golf course is in Sunlands.
The current boundaries of Sunlands were set in September 2000 for the long established name. They include the Sunlands South and Sunlands North irrigation areas. Most of the irrigated areas of Sunlands are planted with citrus orchards.
Qualco lies on the inside of a bend in the river. Sunlands has a short river frontage at the upstream (eastern) end of Qualco, downstream of Ramco. Sunlands extends almost to the river at the northern end of Qualco, bounded by the Cadell Valley Road, in the vicinity of the area known as Oxford Landing.
