Hart told 9News he had taken a wrong turn before falling into the water.

"I was walking along the coast track, took a wrong turn and I was too stubborn to turn back," he said.

"Spent about three hours climbing along the rocks then a massive wave came and changed everything," he said.

Hart had set off on foot to walk 4500 kilometres across mainland Australia from Wilsons Promontory in Victoria to the top of Cape York in Far North Queensland.

He started the walk in April to campaign for basic income, under which everyone would receive regular and unconditional payments for basic needs.

He was taken to hospital in a stable condition, where he was treated for minor scratches and mild hypothermia.
