Since the 1950s, Thornlie has developed in approximately five stages; north-east Thornlie (1950s-60s), south Thornlie (1970s-80s), Crestwood (1970s), Castle Glen (1980s) and Forest Lakes (1990s).
Thornlie is primarily a dormitory suburb with strong transport links to employment elsewhere in the metropolitan region. Albany Highway connects the suburb to the CBD, Roe Highway links it the regional road network, bus services are fairly frequent and a passenger rail service terminates at Thornlie railway station. Retail services are provided through local and neighbourhood centers the largest of which is Thornlie Square Shopping Centre (1970s) and the Forest Lakes Forum (1990s). A range of sporting facilities are available for community usage include lawn Bowls, tennis courts, a skate park, swimming pool, gyms and ovals for cricket and football. Barbagello Park, built in 2007, is the home of Perth Heat, a team in the Australian Baseball League.
