Cricket Australia is keeping the enemies closer as it meet with unregulated international bookmakers to monitor the expected $3 billion bets on Big Bash League.

Cricket Australia is reportedly in talks with international bookmakers such as Philippines’ based SBOBET and the Caribbean-based Pinnacle Sports to better track the level of wager they have been taking on the Big Bash League (BBL), source told Sydney Morning Herald.

The KFC Big Bash League, an Australian domestic Twenty20 cricket tournament, has reached its midway point. It runs from December 17 2015 to January 24 2016 and looks to be on track to top last year’s AUD2.2b wagered over the five-week contest.

SBOBET as well as other international betting exchanges such as AAStar and Citibet are thought to be the major players not only on taking bets on BBL, but also for bets made by Australian punters on other sports.
