Rain continues to play havoc with horse racing in NSW with two provincial thoroughbred meetings the latest hit by wet weather.

Racing officials on Wednesday were forced to postpone one race meeting and transfer another after two racecourses failed track inspections.

But all is not entirely lost for the industry with Saturday's meeting at Kembla Grange, south of Sydney, to be held on Monday.

Gosford will now take Kembla Grange's place in the Saturday afternoon timeslot, staging a meeting originally scheduled for Hawkesbury on Thursday.

A Hawkesbury inspection on Wednesday revealed the track was unfit for racing with surface water covering part of the recently extended home straight.

Kembla Grange was also inspected on Wednesday before officials decided to postpone the meeting.

A Goulburn meeting on Friday has been switched to Canberra's synthetic track.

The Australian Turf Club has been especially hard hit during the past week.

The club was forced to abandon racing at Randwick last Saturday after three races before losing a Warwick Farm meeting on Tuesday.

The financial impact of lost wagering turnover is substantial but the ATC's Matt Rudolph said it was also a blow to owners and trainers.

"It's the cost to the industry full stop in lost turnover but also, the owners and trainers don't get the opportunity to run," Rudolph said.

Racing went ahead at Canterbury on Wednesday despite the track receiving more than 120mm of rain during the week.

Canterbury is regarded as having the best wet weather surface of Sydney's four racecourses.

"The track is racing really well," jockey Peter Robl said after winning two of the first four races.

Because of the interruption to the racing schedule the ATC has received 142 acceptors on an expanded Rosehill card on Saturday.

Rosehill was rated well into the heavy range at acceptance time after receiving 24mm of rain since Tuesday.
