Mithaka traditional owners have been awarded native title over a huge area of Queensland land and water that rivals Tasmania in size.

The Federal Court, sitting in Windorah in south-west Queensland, made the ruling over 55,425 square kilometres, which is only about 12,000 square kilometres less than Tasmania.

A statement issued by the Queensland South Native Title Services said the claim area covers 33,820 square kilometres in the Diamantina and Barcoo Shire Councils.

The claim, which was first lodged 13 years ago, includes parts of the Barcoo and Diamantina Shires encompassing the "ghost town" of Betoota.

Queensland Natural Resources Minister Anthony Lynham said Tuesday's determination protected the Mithaka people's rights to access their lands to hunt, fish, teach and conduct ceremonies.

Elder George Gorringe, 68, said it represented a time of renewal for his people.

"We're going to celebrate tonight," he said.

"We're going to connect up and dance on this country and really enjoy our time together and we'll talk about the future tomorrow."

He said the determination would give the Mithaka People a say in how they worked with other groups in the area to ensure their land was cared for properly.

"For many years, I have worked on many of the cattle properties and councils, quite often alongside my father, and I have become aware of the many traditional cultural sites on our land," he said.

"The recognition of native title means I can now be involved with our Mithaka People and our many friends on stations and in the shires to make sure these sites and traditions are looked after so they will last forever."
