Thoroughbred horse racing is a spectator sport in Australia, and gambling on horse races is a very popular pastime with A$14.3 billion wagered in 2009/10 with bookmakers and the Totalisator Agency Board (TAB). The two forms of Thoroughbred horseracing in Australia are flat racing, and races over fences or hurdles in Victoria and South Australia. Thoroughbred racing is the third most attended spectator sport in Australia, behind Australian rules football and rugby league, with almost two million admissions to 360 registered racecourses throughout Australia in 2009/10. Horseracing commenced soon after European settlement, and is now well-appointed with automatic totalizators, starting gates and photo finish cameras on nearly all Australian racecourses.
