A Midsummer Night's Dream and two sessions of The Owl and The Pussycat did not go ahead at Dubbo Regional Theatre and Convention Centre (DRTCC).

Saturday's performance of Club Soda has been postponed to August 28, one of several shows to reschedule.

COVID restrictions have cut the theatre's capacity in half to 250 seats, and patrons are required to wear a mask, reports DRTCC manager Linda Christof, but despite the challenges she sees positive signs.

"We've had two casualties, there have been two cancelled shows but the rest have rescheduled," she said.

"So that's promising in itself because that means there is confidence out there that things will settle down and we will be back to a reasonable level of normalcy."

Ms Christof said staff were confident in the COVID-safe measures in place.

"We presented Hamlet: Prince of Skidmark during the current restrictions without a problem," she said.

Ms Christof viewed the theatre as "so fortunate" to have major shows including a full house for Opera Australia's Carmen, the Melbourne International Comedy Festival Roadshow and two sell-out performances by Human Nature before the restrictions started.

"I really feel for the other regional theatres that had something like three hours' notice to cancel two full-house shows, that's very disheartening," she said.

"But I think generally there is quite a high level of consumer confidence here in the regional centre, and I put it down to a number of things.

"One is I think the confidence in our box office staff, how well they manage change, patrons now realise that they won't lose their money, they will get a refund, or they can get a gift certificate or exchange to another show, so there's confidence there that theatre staff have it under control and will make the transition as seamless as possible.

"So people are still buying tickets, which is great to see."
