Global wagering giant Betfair has abandoned its rugby league offering just a month out from the season in protest over how much betting companies should pay in gambling taxes.

The betting exchange made the announcement on Wednesday night as the feud between Australia's biggest wagering firms and the NRL took another twist.

Betfair will not offer its clients the chance to match bets for pre-season matches, including this weekend's All-Stars fixture and other high-profile trials such as the South Sydney and St George Illawarra Charity Shield clash, until it strikes a deal with the NRL.

Betfair and other wagering firms have been at loggerheads with the NRL for months over how much the code should charge to allow betting on its matches.
