Lawyers for the late Indigenous politician Ernie Bridge say his case shows why it is important people suffering asbestos-related diseases act quickly.

WA's first Aboriginal MP passed away in Perth at the weekend, at the age of 76.

Just weeks ago he had launched a civil action, alleging his illness was caused by exposure to asbestos while overseeing withdrawal of government services from Wittenoom in the late 1980s.

His lawyer Simon Millman has told the ABC Mr Bridge's family will be able to proceed with the claim, despite his death.

"If people are experiencing the symptoms of asbestos-related diseases, they should seek advice on an urgent basis," he said.

"Then at least the plaintiff will have the peace of mind knowing that his or loved ones can proceed with the claim even in the event that the worst should happen."
