Duranbah Beach, Surfing beach in Tweed Shire, Australia.

Duranbah Beach is a 350-metre sandy ocean beach in Tweed Shire, New South Wales, between the mouth of the Tweed River and the rocky headland Point Danger, which marks the Queensland border. Vegetated dunes run along 200 metres of it. At the southern end are BBQs, sheltered picnic areas, and a block of toilets and showers just behind.

In 1956 Jack Evans built the Snapper Rocks Sea Baths, with an adjacent shark pool for public viewing; the pools were moved to the Tweed River mouth in 1961. The beach later became known for its surf break, hosting the Quiksilver Pro Gold Coast alongside Snapper Rocks and state, national and international bodyboarding contests.

Duranbah is known among surfers for its consistent, powerful waves, and on good days you can watch riders of all levels sharing the water side by side. The beach has a place in the international surf calendar, and that reputation draws people from far away who come simply to watch or take part.

The southern end of the beach is where the facilities are, so it is the most practical starting point for a visit. Before heading into the water, check local surf reports, as wave conditions can change quickly and vary a lot depending on the tide.

A headland near the beach marks the exact border between New South Wales and Queensland, so you can step from one state into the other in a single stride. Because the two states follow different time zones, crossing this point also means moving an hour forward or back depending on the time of year.
