Racing Orange's biggest race meeting of the year - the Orange Gold Cup - will be closed to the public, like every race meet across the country, but trainers, jockeys, stablehands and media will be monitored by Racing NSW staff before being allowed in.

The last meeting at Towac Park, on March 22, was also closed to the public but only jockeys were required to have their temperatures tested.

Friday's meeting is Racing Orange's last for the season, and to go on behind closed doors is a cruel blow for the club which was stripped of meetings in January because the racecourse was too dry to allow for racing.

Friday's meet will wrap up this season and the club was briefed on security guidelines on Tuesday.

Central District and Western Racing Association chairman of stewards Todd Smith said it was a tough measure for clubs across the state, however no-one was complaining if it meant racing could go on.

"Everyone wants it to continue and if these are the steps we have to take then that's what we'll do," Mr Smith said.

He said while it had been a tough season for the club, having racing back at Towac Park was still a win after a difficult year for all involved.

"It's probably disappointing for the club being a showcase meet that they can't have a crowd there but all the prize money is still on offer for trainers," he said.

"Everyone understands why it's happening."

"We're extraordinarily thankful to the government that we can continue to do what we do and keep people's livelihoods continuing."

He said no-one had been turned away due to a high temperature, but said most trainers, jockeys and officials knew if they had a fever to not attend.

"People have been told if they feel unwell or have a temperature do not come to work. It's what's best for them, for their stable and for everyone," Mr Smith said.

He said he expected about 70 people in attendance on Friday, from stablehands to Racing NSW officials.

Temperature tests would be conducted by Racing NSW staff.

Thoroughbred racing isn't the only industry impacted across the region.

Greyhound racing, which has continued in Dubbo and Bathurst, is also held behind closed doors with mandatory testing for trainers, while harness racing also has similar measures in place.

Kennerson Park manager Jason Lyne said it was vital to have the testing.
