The outdoor pro-wrestling show, 'The Return', took place at Berkeley and drew several hundred fans who had been starved of live entertainment.

However, the promotion's show planned for this Saturday has been cancelled due to the current lockdown, after having sold 70 per cent of tickets.

Promoter/wrestler Luke Potter estimated the typical overhead for one of their shows was about $2500.

"We were just starting to get a bit of momentum to be honest," he said.

"Now it's all back to square one again. It's disheartening, we were just starting to get back on our feet.

"When it started kicking off in Melbourne again, we knew there was every chance it could happen up here.

"But I always say there's a lot more people worse off than us.

"The biggest headache is rescheduling, and you just don't know what the future holds."

Potter also runs a training school, teaching aspiring pro-wrestlers the intricacies of the craft.

However, he said he was considering "pulling the pin" on the school, due to the financial impact of having ongoing overheads amid the restrictions.

Jamberoo horror/fantasy writer Alan Baxter was scheduled to appear at the Perth leg of the Supanova Comic Con & Gaming convention last weekend.

The event has been postponed due to the growing COVID-19 cluster in NSW.

This leg of the pop culture event has been postponed due to many of the crew, exhibitors and guest stars being based in NSW.

Baxter said while he wasn't out of pocket in terms of flights and accommodation, such events were a crucial opportunity to network, meet fans and sell books.

"These events were just starting up again, and it's a huge part of what we do," he said.

"The sales themselves are important - you do these big tours and you can shift a few hundred books.

"But it's also that public awareness, that intangible benefit of just being out and about, on the circuit, meeting people and doing things.

"It's a large part of what I do - workshops, conventions, all these things keep getting cancelled or postponed.

"It's taken a hit, we've really noticed it."

Baxter also co-runs a kung fu school in Kiama.

While the Kiama LGA isn't subject to the lockdown, with a number of their students living and working in Shellharbour and Wollongong, they decided to close the school for a couple of weeks.

"We're just working under the assumption that it's that close (to Kiama) that we're going to follow the same lockdown rules," he said.

"It's a pain, because that income is gone, it's done. We just have to tighten it up a bit and hopefully get back to it after the school holidays."

Other events throughout the region, from school holiday show to fundraisers, have felt the financial impact of COVID-19.

A Merrigong Theatre Company spokesperson said all events at the IPAC and Wollongong Town Hall between June 26 to July 9 (inclusive) are cancelled or postponed, in line with the NSW public health order.

"We'll continue to monitor the situation and operate in accordance with NSW Health guidelines," the spokesperson said.

"We are currently contacting all ticket holders regarding ticket refunds and exchanges, and urge everyone in our community to stay safe.

"We all hope to see you back in the theatre sooner rather than later."

Among the shows affected is the live stage adaptation of David Walliams' best-selling book, The Midnight Gang, which was due to visit the IPAC from June 30 to July 1.

Restrictions have also meant fundraising events have had to be postponed.

This includes an event planned to help support a young Illawarra man and keen rugby league player, Cooper Winkelbauer, who is on the long road to recovery after surgery to remove a brain tumour.

"Rockin' for Cooper" was due to place last Saturday at Diamond Dogs Music Lounge & Bar, Dapto.

The fundraiser was to include musical bingo, DJs and karaoke.

However, Cooper's mother Erica said the event was unable to take place as scheduled.

"Unfortunately the night could not go ahead, so we are looking at the fortnight after the lockdown ends," she said.

"Hopefully if all gets back on track with Cooper's rehabilitation, (and) now he's been moved to Port Kembla Hospital, he will be able to attend.

"This lockdown has now left my 19-year-old son in hospital alone without any support as no visitors are allowed to enter the hospital. I just hope the lockdown won't affect his recovery and care."
