Allambie Heights is a suburb of Northern Sydney, in the state of New South Wales, Australia 17.5 kilometres north-east of the Sydney central business district in the local government area of Northern Beaches Council.

It is likely that a "goat track" that roughly follows the existing Allambie Road today was used by the Aboriginal people to access the ocean beaches at nearby Manly.

[3] Many of the streets in Allambie Heights are named after notable battles (particularly where Australian Troops served), and prominent allied political leaders of World War II.

The area is also home to a number of Australian Aboriginal rock carvings, one of the outstanding examples being the group in Gumbooya Reserve.

[5] Bushfires have destroyed much of the bushland area in recent years, however this is part of the Australian ecology cycle and the forests regenerate fairly quickly.
