It was originally a rural area with farms for egg production, horse breeding properties and boarding kennels for cats and dogs. These farms combined gave the area a population of less than 500 people.

The current environment is just undergoing major changes; plans for the next 5 years^[timeframe?] will see the suburb totally redeveloped into medium-density residential properties with an average block size of 700 m² (7,500 sq ft). The result will be a population increase to above 15,000; along with this will be the building of all the necessary infrastructure like shops, schools, parks and gardens.

The region bounded by Ranford Road, Passmore Street, Matison Street and Holmes Road, is likely to retain its special status and unique lifestyle for the foreseeable future. Most residents are deeply involved in either greyhound racing or the breeding showing and trialling of pedigree dogs and/or cats. Several boarding catteries and kennels are found in the area, servicing a large proportion of the Perth metropolitan area.
