There are approximately 200 coastal shacks in the Royal National Park in four communities from north to south, Little Garie, Era, Burning Palms, Bulgo.
The shacks were built in the first half of the twentieth century, many during the depression. They were built by private citizens using their own initiative, resources and labour. None of the communities is accessible by road. All materials were carried down steep bush tracks or around the shoreline.
There were once such shacks up and down the NSW Coast, however most have now gone, swallowed up by coastal development.
The Royal National Park Shacks are the largest remaining group of coastal shacks in Australia. Their heritage significance has been recognised with their listing on the State Heritage Register in 2012 and previously by the National Trust, the Australian Heritage Commission and Wollongong City Council.
