Five NSW country features have received significant prize money increases this season.

The Port Macquarie Cup, Goulburn Cup, Wellington Boot, Tamworth Cup and Wagga Wagga Town Plate will all be worth $150,000.

"These are well-established country feature races," Racing NSW chief executive Peter V'landys said.

"The increase will provide impetus for the clubs to further develop these race meetings and build their recognition not only within racing, but to their local community."

Racing NSW has also expanded the schedule of Showcase race meetings from 40 to 45 in 2017/18, upgrading five key country carnival race days to a minimum of $30,000 per race.

The number of country TAB meetings will also rise from 645 to 664.

"The Showcase meetings continue to provide a tremendous opportunity for country participants to race for great prize money on a regular basis," V'landys said.
