They won't Bob ... all sporting bodies either thrive or struggle based on Government grants, gambling tax rate and gambling laws, subsidies to pay junior fees, ground improvements etc etc .... they will not risk alienating an incumbent government ..
And with Albanese tying himself so completely to a yes vote, both politically and professionally ... the pressure to kowtow will be too great ... throw in all the state Labor government "influence" ... and it would almost be suicidal to oppose ...
You would have to wonder why ... every major sporting body has or will issue statements supporting a yes vote ... of their own free will .. yep .. must be of their own free will ..
