The Australian Turf Club has sent 40 television sets to the flood damaged Lismore and Murwillumbah clubs and donated cash to the SES to help with the recovery.

Lismore and Murwillumbah both suffered substantial damage when the courses were flooded in late March.

As part of the assistance, the ATC has sent a total of 40 TVs to both race clubs.

The television sets had been kept as surplus stock after new ones were installed at Rosehill as part of the refurbishment at the Sydney track.

Lismore secretary-manager Scott Jones said TV screens moved to a second level of the grandstand did not escape the rising waters.

"The jockeys' room is low down so we moved a number of things to a second level where they would normally be safe, and the water still got to it all," Jones said.

"In the betting ring where the TVs sit under the roof the floodwater rose all the way to the gutters.

"We have lost a lot of property and there are many things to replace, so we are incredibly grateful to the Australian Turf Club for this generous support.

"It is just one of many extra costs that have been taken out of the equation."

Tweed River Jockey Club secretary-manager Brian Charman said water levels across Murwillumbah and the racecourse were three times higher than previously seen.

"Everywhere we walk across the course has been affected, and things such as TVs and furniture were things we would not have been able to replace on our own," he said.

"Our board has been blown away by the support of the ATC and Racing NSW and when people come to our next race meetings they will be amazed at what we have been able to replace."

The Australian Turf Club has offered the clubs excess furniture to replace other equipment lost or damaged in the floods.

The ATC's Community Engagement Program accepts requests from across the racing industry for help, and has previously donated barrier stalls, running rails and other racing infrastructure to NSW race clubs.
