While COVID-19 restrictions are continuing to gradually ease, the Aquatic Centre will still need to adhere to strict public health orders, however, there are no time limits for leisure swims.

Orange Mayor Reg Kidd welcomed the news and said the opening of the outdoor pool was a sign summer and Christmas were right around the corner.

"We've all had a really tough year this year and the Orange Aquatic Centre has managed the restrictions imposed by the government to combat COVID-19 extremely well," Cr Kidd said.

"We're at the point now where the complex is permitted to hold 450 people, that's about half the capacity but it's a balance between keeping people safe and making sure we can still enjoy the freedoms we're used to."

Orange City Council's Sport and Recreation Chair Jason Hamling said he was happy to see the pool open, which would allow more residents to enjoy the facility.

"If you'd like to swim laps you'll need to call ahead and book a lane but for just having a muck around with mates in the sun and the water, you can come along anytime within the opening hours," Cr Hamling said.

"We'll be keeping a close eye on the restrictions as we head into summer and we hope we'll be able to accommodate everyone but in the meantime please be respectful and understanding of the government imposed caps on numbers."

The leisure pool and 25-metre pool are also open.

Those whishing to swim laps are asked to phone ahead to book a lane.

Lap swimming sessions are one hour but there is no time limit on leisure swimming.

Parents and children in Learn to Swim lessons may also stay after the lesson for swimming for as long as they like.

Opening hours for the pool this week are Monday to Friday 5.30am to 7.30pm, Saturdays 5.30am to 7pm, and Sunday 8am to 7pm.
