Lighthouse Theatre manager Xavier Dannock said the majority of shows had been rescheduled to a later date.

Mr Dannock said the COVID-19 social restrictions, including different rules in different states, had made it difficult for productions that did large country tours.

"They do a fairly big loop but with the social restrictions it's hard to tour," he said.

The popular children's show Bluey is one of the productions which has been rescheduled for next year.

Bluey, a cartoon which follows a family of Blue Heelers, is one of ABC TV's most popular children's shows.

The production was quick to sell out when tickets were announced for Warrnambool earlier this year.

Along with Bluey, John Williamson, The Sapphires, Carmen and The Resilience Project have also been postponed.

Mr Dannock said a lot of work was being done to refund ticket holders or transfer tickets to a different date.

"We're also doing a lot of planning for 2021 and putting a lot work into that," he said. "We're also promoting shows from other spaces on our social networks."

Through the Lighthouse Theatre's Facebook page people can view performances from the Sydney Opera House and the Arts Centre in Melbourne.

Mr Dannock said the most up-to-date information was available via the Lighthouse Theatre website and although the box office was closed people could call for inquiries.

A statement on the theatre's website states all ticket holders to postponed or cancelled events will be contacted and refunds will be made if a performance is cancelled or if a ticket holder cannot attend the new performance date.

The theatre was closed in late March to help stop the spread of the coronavirus.
