Several hundred Katherine residents have now registered their interest in pursuing the Department of Defence for compensation over the chemical contamination of their water.
Despite a poor turnout of fewer than 20 people for the hastily organised meeting with Maddens Lawyers in Katherine on Monday night, there is a strong roll-up expected for the Shine Lawyers presentation tomorrow night.
A spokeswoman for the firm said there were now 170 registrations for the Shine Lawyers meeting at the Godinymayin Yijard Rivers Arts & Culture Centre at 6.30pm on Thursday.
Aside from genuine fears about health impacts from a life-long exposure to PFAS, many of them claim their homes and properties are now virtually worthless.
The two law firms propose to launch a class action against the Defence Department.
Power and Water Corporation, Katherine Town Council and even Katherine MLA Sandra Nelson have also been named as possible targets for litigation.
It was also suggested this week that several other law firms may be interested in coming to Katherine to take on the class action as well.
The Defence Department freely admits it has caused the contamination through its use of firefighting foams at the Tindal RAAF Base between 1998 and 2004.
The department has also said it would defend any legal action.
Although similar class actions are more advanced at Oakey and Williamtown, none have reached court yet.
Both legal firms are keen to register residents to join the class action.
And both say they already have many residents who have expressed an interest in joining the legal action.
