Gilberton is a rural locality in the City of Gold Coast, Queensland, Australia. The population of Gilberton was just 25 people at the 2006 census.
The terrain is flat and low-lying, with an elevation of less than 10 meters (33 feet) above sea level. It is well irrigated by a number of streams. Sugarcane is the primary crop grown in the region, with a minor amount of grazing on native vegetation in the west.
Acid sulfate soil is found in naturally water-logged areas of Gilbert. The lowering of the water table as a result of drainage on the Pimpama River allows oxidation of iron sulphide to produce Sulphuric acid, which can cause damage to both natural and constructed environments by releasing iron, aluminium, and other heavy metals.
