In order to streamline things a little further given how many bets are sent out, the following abbreviations will be used to denote advised bookies (these are the only bookies used in official results and advice, as they are the most commonly used bookies by members that haven't banned or restricted most members). That's not to say they necessarily have the best prices available on any given runner as there are many bookies not being used:

Crownbet: CB
Luxbet: LB
Sportsbet: SB
Tab NSW/VIC: TAB
Topsport: TOP
Ubet: UB
Unibet: UNI
William Hill: WH

Bet365: 365 (note advised for NSW races only)
