Documents released by the Federal Court of Australia show Katherine is set the receive the biggest chunk of the $212.5 million which was agreed on late last month.

Shine Lawyers, who acted on behalf of Katherine property owners, said there were about 2500 property owners involved in the claim.

Katherine Town Council also decided at a late stage to join the action and as the biggest property owner is set to receive the biggest payment from the settlement.

Dividing the 2500 property owners against the settlement would suggest the payments would be in the order of $37,000 each but there are many other factors involved.

Shine Lawyers and its litigation funder IMF Bentham have to paid for taking the action on.

Then there is property size to take into account also.

A further $86 million will be given to the community of Williamtown has won $86 million from the settlement and Oakey $34 million.

The Sydney Morning Herald revealed last week that the chances of a future lawsuit on health consequences from the contamination were bolstered after the Federal Court's independent scientific umpire ruled there was "good evidence" the PFAS chemicals potentially cause harmful health effects, including cancer.

According to the newspaper, the settlement does not include any admission of liability by the government, which has been released from any further claims arising for compensation over property losses, mental anguish or nuisance.

Shine Lawyers has said a scheme to distribute the funds to individual households is still being negotiated and is expected to be finalised in coming months.

Senator Malarndirri McCarthy said: "This landmark settlement is welcome news, especially in the NT.

"This has been a long journey for the people of Katherine, a community severely impacted by PFAS contamination from the RAAF base.

"I have walked alongside those families as they gave evidence to the Joint Standing Committee on PFAS and showed courage, strength and determination.

"The launch of this class action was direct result of lack of action from the Federal Government by people who felt unheard and ignored.

"This is a win for those families. Well done."
