  • Back in the days when off track bookmakers were illegal in Australia, an SP bookie or often just SP was a bookmaker who would take bets and then pay them out (if necessary) at the starting price, ie. the odds that were offered by on-track bookmakers at the time the event started. SP bookies were relatively common as police had better things to do than hunt down the weedy guy in the corner of the pub with a big satchel full of money. Larger operations were known to have people peering over the racecourse fence with binoculars to read the odds boards in the betting ring and these numbers would get phoned in to the the nearest payphone of course! Those were the days.
