Leisureland Fair, Amusement park in Langwarrin, Victoria, Australia

Leisureland Fair was an amusement park in Langwarrin featuring attractions such as a steel roller coaster, log flume, water slides, and mini-golf. The large outdoor grounds were organized to accommodate diverse rides and entertainment across different sections.

The park opened in 1984 and operated for 8 years before closing in 1992. The site was subsequently redeveloped into a residential community after operations ended.

The former Function Centre, known as The Castle, stood at the centre of the park as its main terminus. After the site became housing, the building was renovated inside and now serves as the Bait-ul-Salam (House of Peace) Mosque and cultural centre for the Australian Ahmadiyya Muslim Community. A street named after the park is the other trace of it.

The park site is now a housing estate in Langwarrin; the only street reference is a road named after Leisureland Fair. The former Function Centre, known as The Castle, stands in the middle of the estate and now serves as the Bait-ul-Salam mosque and cultural centre. Visitors should approach it as an active place of worship, not a park ruin.

The former Function Centre, called The Castle, stood at the centre of the park and served as the main terminus of the steam train line from the carpark. It survives as the Bait-ul-Salam mosque and cultural centre of the Australian Ahmadiyya Muslim Community, its interior heavily renovated.
