Twilight Zone.  Tsk, tsk, tsk...

Kati Thanda-Lake Eyre was declared a national park in 1985 — a development that ensured the site was subject to various protections under South Australian law.

According to the SA government, recreational activities "including swimming, driving off designated tracks, boating and landing aircraft" were restricted as a result of the national park declaration.

Kati Thanda-Lake Eyre is a sacred site for the Arabana people, who were granted native title over land covering most of the lake in 2012. The Arabana people co-manage the Kati Thanda-Lake Eyre National Park with the National Parks and Wildlife Service.

"Lake Eyre or Kati Thanda is our home," Arabana Aboriginal Corporation director Colleen Raven Strangways said.

"This is where my ancestors walked for over 65,000 years, this is where my ancestors lived, camped, had families.

"Generations and generations of families have lived off that lake."

According to the current management plan for the national park, the 2012 native title determination gave "Arabana people certainty, and a major influence on what happens on their land".

"Native title rights enable Arabana people to hunt and camp on their lands. They also have the right to negotiate with companies regarding any mining activities on their Country," the plan states.

"It gives legal acknowledgement of what they have always known: this is Arabana Country."

Arabana say their ancestors and spiritual beings live on the lake and it is where they get their law and spiritual learnings from.

They wanted to limit foot and vehicle traffic to protect the lake-bed and surrounding ecosystem.

"We don't want boating on there, we don't want people walking on there because when you walk on that lake, it stays there until the next big flood," Ms Strangways said.

"It stays there, it doesn't go away … the ecosystem is so fragile and so important to the health of that lake and to the health of its people, my people, the Arabana people.
