A-League clubs are demanding a forensic financial audit of FFA's books – and have threatened court action if their demand is not met.

The clubs – increasingly angry over what they claim is an inadequate share of the spoils from the governing body's revenue-sharing model – want full disclosure on where money has been spent over the past three years, and an explanation why their payouts are insufficient for them to cover costs.

Earlier this week FFA offered the clubs $3.55 million for the upcoming season, which came with several conditions. That failed to bring agreement over a row that has been escalating in recent months.

The clubs want a significant rise in their share of broadcast, merchandising, sponsorship and ticket revenue after years of collectively incurring losses.
