The Racing Industry had made it very difficult for Betfair to operate in Australia.
The Racing industry is now making it very difficult for Betfair to continue operating in Australia.

I see it as the Turnover Operandus is irrelevant.

It is no coincidence that Victoria followed NSW example.
I see it as the Racing Industry simply want Betfair out.

I don't quite see the motive , but feel that the Recent New Contract with TAB that mentions the possibility of TAB operating as a Betting Exchange may be at least part of it.
Part of the motive may or may not be a drift of TAB Punters to the Exchange Operators , and that may not be a good thing for the Australian racing Industry.

Like I said , it's not about Betfairs Turnover , but Betfair itself.
