A class action is set to begin against airlines including Qantas and Air New Zealand for alleged engagement in a freight price fixing cartel.
A dozen international airlines including Qantas will be taken to the Federal Court next year over allegations of fixing air freight surcharges.
Law firm Maurice Blackburn filed a class action against the airlines in February 2007.
Qantas, Air New Zealand, Singapore Airlines, Cathay Pacific, British Airways and Lufthansa Cargo are alleged to have engaged in cartel conduct between January 2000 and early 2007.
The class action seeks damages on behalf of air freight customers who paid more than $20,000 to have goods transported to Australia.
"This has been a long haul, but we are determined to see the group of members, mostly shippers of freight from small businesses to large multinationals, get compensation for the losses they allege they suffered at the hands of this notorious cartel," Maurice Blackburn principal Brooke Dellaveodova said in a statement.
Justice John Middleton has ordered the parties to attend mediation on November 25 and 26, ahead of a Federal Court hearing set to start in October 2014.
Maurice Blackburn are operating on a "no win, no charge" basis with litigation firm IMF Australia.
The Australian Competition and Consumer Commission (ACCC) has been investigating possible price collusion among the airlines for many years, resulting in fines of nearly $100 million.
