The change brought in by NSW Chief Health Officer Kerry Chant on Tuesday encouraged sports to cancel zone, regional or state championships or competitions from Wednesday.

However, the definition of zones has not been made clear by the government and left many sporting organisations confused about the remaining competitions.

Northern Inland Football competitions administrator Toby McVey said he believed the new recommendations shouldn't mean the cancelling of community sport.

"We are in a bit of limbo at the moment because we are still waiting on clarification on what it all means," Mr McVey said.

"At the moment, we're still going ahead with our Premier Division and Namoi League competition games this weekend until we hear differently.

"It would be a massive shame if it came to an end early because all of the clubs committees, players and volunteers have put in a massive amount of work, so it would be a sad and sorry way to end the season."

AFL North West tribunal co-ordinator Josh McKenzie said he was hopeful the season could continue.

"Like everyone, we are waiting on clarification," Mr McKenzie said.

"I have heard some anecdotal talk that the regions might be restricted to local government areas, but that hasn't been confirmed.

"If that were to be the case our competition would be in a bit of trouble, but due to the lack of clarification we are still hopeful we can continue."

Mr McVey said while this weekend's Premier and Namoi League games may still go ahead, some representative competitions had already been postponed.

"We are just at the half-way point of our season and starting the second round of our fixtures this weekend," he said.

"However, our Northern League One teams who participate in Newcastle will have their fixtures postponed for at least this weekend.

"In terms of the rest of the competitions, if the advice we get is to postpone, I dare say the easier option may be to just cancel the remainder of the season."

Moree Services FC coach Matt Urquhart said it's "business as usual."

"We don't have many concerns. We don't have huge crowd numbers. We don't have the canteen or the bar running or anything like that," he said.

"The same rules apply, just tell people to follow the rules that they've got to follow when they're out in public.

"No real change for us as of yet."
