Maianbar is adjacent to the village of Bundeena, less than kilometre away and linked by a bush track, and footbridge. It lies on the southern side of Port Hacking, opposite the suburbs of Burraneer, Dolans Bay, Port Hacking, Lilli Pilli and Cronulla. Maianbar is surrounded by the Royal National Park.
Maianbar means deep tank or waterhole in the Gamilaraay language. The name initially referred to the site of local marine fish hatcheries and was probably chosen by the Trustees of the Royal National Park. Areas of today's suburb were known as Fishermans Bay Estate and Sand Spit Estate until 1951, when Sutherland Shire Council officially named it Maianbar.
There are many artists in both Bundeena and Maianbar. The residents host a monthly art exhibition in local artists' houses, called the Art Trail. The Art Trail is held on the first Sunday of every month. Art Trail Website The Art Trail is free of charge and provides local artists with an opportunity to sell their artwork.
