Early industries in the suburb were dairy and poultry farming, honey production and table grape growing.
The suburb is home to a number of recreational clubs including the Brisbane West Tennis Centre which opened in the early 1980s, Richlands Tenpin Bowl which opened in 1991 and the Darra Oxley Pony Club.
