There are still heaps of independents left, but most of them focus on racing more than sports and don't have good international coverage.
BlueBet, Picklebet, PlayUp, BetDeluxe, Jimmybet, Palmerbet are all ok for some stuff.
Lately I have been using
Sportsbet.com.au (PaddyPower),
Unibet (KAMBI) and
Bet365 the most.
NEDS, Pointsbet, Ladbrokes, BetGold also all useful.
I think there is over 100 licensed bookmakers in my state.
