Ironfest brings the weird and wonderful to book out our hotels and motels, shop in local businesses and overall boost Lithgow's economy.

It has been running for the past 20 years and its organisers are discussing future options to let the festival continue to grow.

Ironfest founder Macgregor Ross, along with other Ironfest organisers, is in discussions with Casula Powerhouse Arts Centre about holding a potential second annual event.

"We are very portable, very mobile, we have the potential to travel. I'm starting to think about Ironfest as a secondary event.. even if we take three-quarters of what we've got happening here," he said.

Mr Ross said the first event each year would be held in Lithgow as a premiere and then have a second one six months later in Casula.

"Truly Ironfest is based here, it always will be, we're not moving away from Lithgow but the idea is to gradually change and by doing this the possibilities are endless," he said.

There is currently a tentative booking for the event to be held in October 2020 over the long weekend in Casula.

Casula Powerhouse Arts Centre director Craig Donarski visited Lithgow Ironfest this year along with Casula mayor and other council staff.

"We had an awesome time, I thought the festival was of difference and diversity, magnificent obsessions and peculiar hobbies," Mr Donarski said.

He said Ironfest had grown into a gloriously unique event and Lithgow was bursting at the scene when it was on, bringing an amazing injection of people to the town.

"It's a delightful festival, we don't want to take anything away from the Lithgow festival but we want to enable Ironfest to grow, it's the next step not the last step," he said.

Mr Donarski said the event could be set up at the Casula Parklands.

"We have 21 hectares of land, it's a pretty spot to hold an offshoot version and take a bit of the pressure off the April event in Lithgow, it will help the future of it," he said.

He also said it was amazing to see Lithgow City Council's support of the event.

"It definitely throws down the gauntlet, we'd love to rise to the challenge," he said.

Lithgow mayor Cr Ray Thompson said he was aware of the discussions and it was still early days.

"We haven't gotten into the depths of it, there's still a lot of things to be discussed," he said.

Cr Thompson said Lithgow Council would be meeting with Liverpool Council at the end of the month to get each other's thoughts.
