The ride-sharing company is alleged to have acted in complete disregard for any regulations which existed in the markets that it entered, according to a summary of the litigation.
"As a result, Uber had an unfair competitive advantage against taxi and hire car industry participants who were complying with the law," alleges Maurice Blackburn.
Uber said it had not yet received any notice of the class action, which was filed on Friday in the supreme court of Victoria.
"Over 3.8 million Australians regularly use Uber as a reliable choice to get from A to B and governments across the country have recognised ride-sharing as part of the transport mix," said an Uber spokeswoman.
"We are focusing our efforts on delivering a great service to riders and drivers in the cities where we operate."
Last week Uber published details of its planned stock market flotation, which it hopes will value the decade-old -sharing company at US$91.5b — more than double the value of Ford Motor Company.
But the prospectus also details a tidal wave of legal claims from its own drivers, including 60,000 people in the US, who argue they should be treated as employees rather than contractors.
