Extensive grazing holdings are also prevalent in the district.

To the west of the town is an area known as The Gemfields, with small towns such as Sapphire and Rubyvale indicating the type of gems found there.

The Fairbairn Dam , a short drive to the south of the town, was opened in 1972, and holds back the waters of Lake Maraboon .

The extensive water supply has allowed the cotton industry to flourish here, as well as being a boon to local water sports.
