The much-loved Stoney Aqua Park is returning to operation this weekend

The park is reopening from 10am to 4pm on Saturday and Sunday, September 11 and 12 for the first time since disastrous floods in March this year.

Under the revised rules for some parts of regional NSW from September 11, major recreation outdoor facilities including stadiums, racecourses, theme parks and zoos can reopen with one person per 4sqm, capped at 5,000 people.

Flood water devastated all of the holiday park cabins, front office, staff quarters, kiosk and the manager's residence. Inflatable equipment was also spread across the park and onto neighbouring properties.

Owner Jason Stone said the rebuild is running ahead of schedule and the park will be opening before initial estimates of the September school holidays.

"We were pretty much completely levelled in March and we had to do a complete rebuild," he said.

"The recent news of the lockdown lifting coincided with us running ahead of schedule so we thought we'd open it up with a bang. Hopefully we can have a great reopening weekend and school holidays.

"We have all new equipment ordered from overseas, it's a one third bigger again (than last time) and there are a heap of new attractions out there as well.

"We're looking forward to getting people out of their houses and we will run seven days a week over the school holidays."

The Stoney Park man-made lakes were built in 2000, just after Jason and his family moved to the area, and offered a range of waterski and wakeboarding fun for locals and visitors before the inflatable aqua park was built in 2017.

Mr Stone said staff and tradesmen have been working around the clock to get the park open again.

"We're pretty much on track with all our accommodation rebuilt and we will open those next weekend," he said.

"We have a new land park inflatable ninja obstacle course with over 350 metres of obstacle running, which will be up in the next couple of weeks.

"We're in over $300,000 to get it all up and running again. Everyone has been working around the clock to bring the park installations to fruition.

"The light at the end of the tunnel has slowly been getting bigger and we're excited to get everyone going again."

Mr Stone said the traditional waterski competitions will return to the back lake section of the park later this year or early next.

"We will still be having competitions on our ski lake. We have junior camps who rent the lake and we have about four NSW waterski events coming up," he said.

"We are currently setting those dates and we expect to have one or two competitions towards November, December and a couple in the New Year."
