A French mining company seeking to exploit uranium-rich land surrounded by Kakadu National Park is calling for the Federal Government to explain why it has promised to stop future mining.

Earlier this year, the sole traditional owner of the Koongarra area asked the Federal Government to incorporate it into the World Heritage-listed park.

The owner wants it protected from being mined by AREVA, which has held applications for a mining lease and an exploration licence on the land for the past 15 years.

Yesterday, Labor promised to include the area in the park if it is re-elected.

In a statement, AREVA said it was "surprised" by the Government's election commitment.

It says it has heard nothing from the Government since it made a submission on the issue in May.

AREVA wants the Government to explain its decision and says it is now seeking legal advice.

"AREVA considers that it is essential that the next government follows a proper decision making process, including taking into account all stakeholders as well as the views of other cabinet ministers," the company said in a statement.

Meanwhile, Tourism Top End says it is hopeful Labor's pledge to expand Kakadu will mean more areas will be opened to tourists.

"I think it's a positive move and that is a beautiful area," Tourism Top End's Sylvia Wolf said.

"There are a lot of beautiful areas in Kakadu that haven't been opened and I'm hoping with the present attitude there will be more."
