Victoria-based Maddens Lawyers said there had been an "influx" of new registrations in the past fortnight.

Maddens has offered to take up individual claims in Katherine especially those who may have opted out of the successful class action lodged by Brisbane-based Shine Lawyers in 2018 seeking to sign up people to pursue legal action.

Shine Lawyers eventually registered more than 1000 residents and won a class action settlement from the Defence Department for $92.5 million for Katherine in March.

Many residents registered late for the class action and it is known many people who had opted out of the class action still believe they are also entitled to compensation for lost property values.

Maddens Lawyers principal Kathryn Emeny said "We have received an influx of registrations from Katherine residents who are interested in advancing individual claims for compensation associated with PFAS contamination.

"Around 30 new inquiries have been received over the last fortnight."

"The nature and level of new enquiries demonstrate that there are a relatively high number of property owners in Katherine that have claims that still can and ought to be pursued," she said.

"Advancing an individual claim is not an overly onerous process and I again encourage anyone that opted out of the PFAS contamination class action that was being progressed by Shine Lawyers to make contact with us via our website www.maddenslawyers.com.au or 1800 815 228," she said.

The legal firm says there are significant benefits to advancing individual claims including the provision of targeted advice and the likelihood of avoiding the delays and expenses often associated with court proceedings.

"People impacted by PFAS in the Katherine area are encouraged to contact Maddens Lawyers via e-mail katherine@maddenslawyers.com.au or on 1800 815 228 to discuss their circumstances and the options available to them," Ms Emeny said.
