An Australian class action is among the barrage of potential lawsuits faced by Volkswagen in the fallout of the German car maker's pollution scandal.
The legal actions could collectively cost Volkswagen billions of dollars while the scandal could ensnare other car manufacturers if they are found to have tampered with the emissions test. 
Volkswagen has admitted it installed emissions-hiding software in 11 million diesel cars worldwide to make them appear cleaner.
Maurice Blackburn's class actions principal Damian Scattini said the firm was investigating a consumer law action against Volkswagen.
Mr Scattini said while Volkswagen was still yet to confirm if any Australian cars were affected, it was likely Australian consumers would be hit by the scandal.
"We believe that if it is confirmed that Australian cars are impacted, then consumers may have grounds to take action against Volkswagen, including pushing for extended warranties given people as yet are still in the dark about the full impacts of this issue," he said.
Mr Scattini said if affected, these cars were likely to be worth significantly less for consumers trying to sell them at a later date.
"Furthermore, if cars here are found to be affected and then need to be recalled and fixed, it is not known what effect this will have on engines, particularly in relation to speed and mileage, all of which, again potentially, will impact on resell options for consumers."
The prospect of legal action comes after the Australian Competition and Consumer Commission's announcement on Thursday that it was investigating whether Volkswagen car owners in Australia were caught up in the scandal.
The federal Department of Infrastructure and Regional Development, which monitors vehicle emissions standards, has also demanded answers from Volkswagen but is waiting for information.
Comment is being sought from Volkswagen.
