Bendigo Theatre Company has decided to postpone two more shows after holding out hope of staging the productions later this year.
The committee of management and Tribe Youth Theatre's committee held meetings over the weekend to work through the impact of COVID-19 on its productions of Beyond Reasonable Doubt and Cats.
BTC president Abe Watson said the committee made the decision to postpone both shows with a heavy heart.
"We are devastated, but we know it is the right decision," he said.
Previously, BTC had postponed most of its 2020 season including its major production for this year We Will Rock You.
But was holding out hope to present legal drama Beyond Reasonable Doubt at the end of the year and Tribe's production of Cats in September and October.
"We had stated that we would explore the possibility of performing Beyond Reasonable Doubt later in 2020," Mr Watson said.
"This is no longer the case, and we will work with the cast and crew to seek new dates as part of our 2021 season."
Tribe's production of Cats had always been scheduled for September and October but the restrictions around large gatherings, lockdown measures and social distancing made proceeding with the show untenable.
Cats had been in rehearsal for weeks and was on schedule to be able to premiere on late September.
"We know this is devastating," Mr Watson said. "It will be postponed, pending contractual negotiations until Season 2021 - or, late 2020, restrictions pending.
"While the four-square-metre rule remains in place for indoor gatherings, we do not see a way to proceed.
"We know that from a production standpoint, we would be ready to proceed in September, however, with the return of stronger lockdown measures we do not have confidence that we will be able to accommodate an audience."
Mr Watson said Cats promises to be a spectacular production when Tribe are able to perform it.
"A great deal of planning and preparation has already gone into Cats," he said.
"The entire Cats company have done an exceptional job, weathering the challenges COVID-19 has placed in front of them, calmly and courageously jumping every single hurdle, all while prioritising the health and safety of all team members."
Mr Watson said Tribe will consider a reduced rehearsal period of Cats to help with the wellbeing of its cast and crew.
"We appreciate that rehearsals have offered wellbeing benefits to those involved," he said. "To that end, we will seek to continue a reduced rehearsal period (in consultation with the team) for as long as government restrictions permit.
"We thank everyone for their support and kind words of reassurance during this tough time. The committee and I sincerely appreciate it. We will see you soon."
