Cumani said it was a difficult task to work through given the different scenarios if racing was shut down.

"Does a racing shutdown mean a training centre shutdown also?

"If we can continue training then it's a completely different story to if we can't train.

"And do they set a timeline on a shutdown like they did with the AFL," Cumani asked.

"All those different things change the picture so much, so we are trying to work through the different scenarios."

Cumani said the worst case scenario was having to put horses out for a spell, which would in turn force the trainer to let staff go.

"We're hoping at the very least than we could continue to train because then the staff have a job," he said.

"We try and take a family approach and a lot of our staff are full-time, which would make it a lot harder.

"If we have to lay-off staff then you need an awful lot of cash for redundancy payments and that might make it prohibitive."

Cumani also questioned whether there were enough safe spelling properties to send horses and was unsure if that system could cope, which might then lead to a horse welfare problem.

He also asked how long would it take to get racing back up and running.

"There could be a lot of horses out for a spell and when racing is ready to resume there might not be the horses to race for a couple of months," he said.

Victorian racing was shut down for almost two days this week, with races lost at Sandown on Wednesday and two race meetings cancelled on Thursday.

Racing in Victoria resumed on Friday after jockey Mark Zahra tested negative to CODIV-19.
