Australia's cricketers' union has warned that player support for a privatised Big Bash League is not guaranteed.

Australian Cricketers Association chief executive Paul Marsh issued the warning on 7 October.

He said players need a financial agreement before backing privatisation.

He was speaking on Wisden's The Scoop.

Under the current deal, players receive 27.12 percent of Cricket Australia's revenue.

The union says players are entitled to that share of any proceeds from BBL team sales.

Marsh said the union would give up its share of sale proceeds in return for a higher share of ongoing revenue.

He called it a win-win.

Cricket Australia rejects the model. It sees privatisation proceeds as different from standard revenue.

There is no agreement in place. The union is seeking arbitration.

Cricket Australia is selling BBL teams to private investors.

The Melbourne Renegades are fully on the block.

The current memorandum of understanding runs to 2028.
