I use betfair for fun and I make about £50 per week and I pay the PC.  It's not just the big gamblers that pay it!

For the Aussies:

Betfair’s Australian operations are regulated by the Tasmanian Gaming Commission in accordance with the Gaming Control Act 1993 (Tas). Betfair is required to adhere to a number of important probity and integrity provisions under this Act,
including:

 the prevention of wagering on illegal events;
 permitting the Tasmanian Gaming Commission to override any betting exchange rules it
deems to be oppressive or unfair;

Would be if the TGM would determine the 60% PC to be oppressive or unfair (which it is). Make your submissions to the Gambling Reform enquiry.

anybody with half a brain would of worked out by now that having to put brakes on the amount that can be won by at least 500 users says just how successful the betfair exchange system is, bookies can add bonuses to certain bets which is the opposite appliction because.

(1)....combinations of reduced odds multiple bets with hs bookies win at a more lesser rate than there implied chances.

(2).....such a winner wont repeat the win rarely.

(3).....hs bookies have many control methods too control and restrict pro-gamblers.

You cant have your cake and eat all the cake, betfair are allowing winners on pc1 and pc2
as the charges allow the payouts to be sustainable, so why dont you stop going on like spoilt
children and get on with using the betfair exchange and agreeing with the choices of betfair and up your own game the way betfair has done for over 10 years now.
