Entertainment venues and groups in Tamworth have been dealt a devastating blow, will all Capitol Theatre performances until July 31 cancelled or postponed amid escalating coronavirus restrictions.
Tamworth Regional Council entertainment venues manager Peter Ross said the health of the general public and people involved in producing events comes "first and foremost".
Council is working with groups and tour companies to try and get the packed program of productions planned for the Capitol Theatre rescheduled until the pandemic is over, he said.
Mr Ross is also the director of Tamworth Musical Society's MAMMA MIA!, which was planned to take the Capitol Theatre stage in May.
"We are looking at rescheduling MAMMA MIA!," he said.
"The Tamworth Musical Society is right in the thick of rehearsals for MAMMA MIA! and it's a great piece of theatre that celebrates life."
It's disappointing on many levels but it's very important that we do this to stem the pandemic and we are absolutely doing our part.Peter Ross
Prime Minister Scott Morrison announced on Wednesday that indoor, non-essential gatherings of more than 100 people should be cancelled.
The Capitol Theatre has a seating capacity of 400, so the show must not go on.
"It's disappointing on many levels, but it's very important that we do this to stem the pandemic and we are absolutely doing our part," Mr Ross said.
Providing the cast and crew remain under 100 people, local groups will still be able to gather and rehearse, he said.
A bunch of performances were expected at the theatre in the coming months including X-Factor star Taylor Henderson, a production of Sleeping Beauty and the Moscow ballet.
The advice has caused cancellations and postponements at three other council venues - TRECC, the town hall and the Tamworth Community Centre.
Mr Ross said new dates for postponed productions and performances will be released as soon as possible.
Ticket holders will be contacted about their options.
Up to date information can be found on council's entertainment website and the theatre's box office will be open for enquiries.
