Seventy-Five Mile Beach, Beach and sand road on Fraser Island, Queensland, Australia

Seventy-Five Mile Beach is a sandy beach on the eastern shore of K'gari (Fraser Island) in Queensland, Australia, about 1,200 km north of Canberra. It lies in a savanna climate where January averages 24 °C and July 18 °C, with about 1,638 mm of rain a year.

Fraser Island, including this eastern coastline, was inscribed on the UNESCO World Heritage list in 1992 as part of the Great Sandy Region. The listing recognised the island's sand mass, freshwater lakes and rainforest growing on sand. The beach lies within Great Sandy National Park, where the Butchulla people hold native title over parts of the island.

The beach lies in Butchulla country, the island's Aboriginal homeland, and its K'gari name means paradise. The Butchulla name for the island was restored in 2023, when the world's largest sand island was officially renamed K'gari alongside its English name Fraser Island.

Drivers need a permit to operate vehicles on the beach and must respect a maximum speed of 80 kilometers per hour, as small aircraft regularly land on the sand. Check weather conditions and local guidelines before setting out to ensure safe travel.

The Maheno, a former passenger liner, was driven ashore by a cyclone in 1935 and its rusted hull still lies on the sand. Further south, the coloured sand cliffs of The Pinnacles rise above the beach, and freshwater springs seep through the sand near the waterline.
