The ink has dried on a $1.3 billion deal between the Western Australian Government and Noongar people for the use of land in the state's most populated region.

It has taken five years to establish the deal, which is part of what has been described as the largest settlement of native title in Australian history.

The six Indigenous land use agreements cover 200,000 square kilometres of land stretching across from Jurien Bay to Ravensthorpe, including the Perth metropolitan area.

Premier Colin Barnett said the settlement would see cash, land, housing and other benefits made available to 30,000 Aboriginal people over 12 years.

"Essentially, that means the settlement of native title across Perth and the south-west," he said.

"There are some formal court procedures to follow but we expect that to go smoothly.

"This has been mutually agreed, it's been a long process, but I think [it's] a great result for Noongar people and the wider community."

Mr Barnett said the deal would now be presented to the National Native Title Tribunal, which would consider any objections to the proposal.

"That will take some months but we would hope within six months that will be concluded and this settlement will come into practical application during next year," he said.

Six claimant groups were represented by the South West Aboriginal Land and Sea Council in the negotiations which have been ongoing since 2009.

As part of the deal, WA Parliament is expected to pass through a bill recognising the Noongar people as the traditional owners of the land and acknowledge their contribution "to the heritage, cultural identity and economy of the state".

Up to 320,000 hectares of Crown land within the settlement's boundaries will be re-allocated to a Noongar Land Estate.

The land will then be transferred to an independent Noongar Boodja Trust, which will also have $50 million deposited into it every year for the next 12 years.

Opposition not expected to be successful: SWALSC

The deal has not been without controversy, with some opponents accusing those in favour of selling their heritage and culture to the Government for cash.

The South West Aboriginal Land and Sea Council (SWALSC) is confident there will be no successful objections to the native title agreement.

The council's chief executive Glenn Kelly said there was a three-month window for people to oppose the deal after it was presented to the National Native Title Tribunal for registration.

"We think we've dotted every i and crossed every t and made sure all the details are right," he said.

"So we don't think there will be any objections that get up, in terms of what you can object to in the tribunal."

Mr Kelly said some people opposed the settlement agreement for their own ends.

"There's some people whose identity is based on being dispossessed. and when something like this comes along which is about empowerment, it really challenges some people's identity," he said.

"As a result, they sort of oppose it because it means taking responsibility and building and rebuilding."
