Stablehands will be among the big winners after significant prizemoney increases announced by Racing NSW.

The state's ruling body is flush with more than A$100 million ($126 million) in funds after last week's ruling by the High Court on the race fields legislation.

Racing NSW will use a portion of those funds to boost prizemoney across the board, unveiling its new structure on Wednesday.

Licensed stablehands, among the lowest-paid workers in the industry, will receive 1.5 per cent of total prizemoney under the changes which take effect from July 1.


"In a first for Australian racing, licensed stablehands will now get a cut of the prizemoney, justly rewarding them for their efforts in the success of their stable," Racing NSW chief executive Peter V'landys said.

Sydney racing is also set to benefit with metropolitan Saturday races to increase from A$70,000 to A$85,000, while midweek city races will be worth A$35,000, an increase of 30 per cent.

The purse for provincial events will rise to A$22,000 while country races receive a 50 per cent increase to A$15,000.

Prizemoney will also be paid down to 10th place from July.
