Wild weather has forced two waterfalls to fly backwards into the air as huge waves batter the coastline beneath.
The reverse waterfalls were created as 70 km/h winds hit a cliff in the Royal National Park south of Sydney, causing the water to blow up and backward.
A video posted to the Bundeena visitor site shows the natural phenomenon occurring on Monday.
It captured the exact moment a rainbow forms in the mist from the reverse waterfall and casts a colourful light across the coast.
The aerial footage captures two waterfalls close together on the side of the cliff top which is part of a popular coastal walk near Bundeena.
The small town is a small holiday destination close to Sydney known for its private bush walks and beautiful beaches.
During the video you can see as the wind drops the waterfall flows down the cliff naturally and then as it picks back up, the water is thrown in different directions.
The local town also experienced minor flooding with one of the main roads into Bundeena and nearby Maianbar blocked off.
A large boulder slid onto another access road in the area due to the heavy rain. Local ferry services were also stopped due to the large sea swell.
People were urged not to walk along the coastal tracks and to stay out of the floodwaters.
The New South Wales South Coast and parts of Sydney have been hammered with torrential rainfall with minor and major flooding across the region.
Hundreds of residents were forced to evacuate low-lying communities around Sussex Inlet and Moruya after more than 300mm of rain fell over the weekend.
Floodwaters rose quickly in Nowra as the Shoalhaven River broke its banks.
The Bureau of Meteorology has since scaled back the warning to ‘moderate flooding’ for the Shoalhaven area.
