The leaking roof deposited water onto one of the courts used during the weekend's opening round of the Barrengarry Conference junior representative competitions hosted by Shoalhaven Basketball Association.

The leak, on court four of the new complex, although not constant was enough to have a volunteer standing by with a towel throughout each game to wipe up any drips to ensure the surface was not slippery or a danger to players.

Council says staff are actively addressing any issues that arise at the Shoalhaven Indoor Sports Centre to ensure these are rectified as soon as possible.

"When council invests in a large building like the indoor sports centre, there is a period of time after completion for defects to be found and fixed under the construction contract, this is quite normal," a council spokesperson said.

While last weekend's rain was constant, it wasn't what you would call torrential.

The opening round of matches in the under 18 and 14 boys along with the under 14 girls, saw Shoalhaven battle it out against sides representing Illawarra, Merruimbula, Moss Vale, Batemans Bay, Goulburn and Wollondilly.

The round of matches managed to be completed, with 24 games played across six different time slots on the day.

But the leak was not a great look for a complex that's only 16 months old.

Described as "three drops every couple of minutes in one spot" while it did not interrupt play, court controller Maddy Hanlon said if the leak had got any worse there was the risk of having to cancel games on that court.

"It would have been a huge embarrassment if we had had to cancel the day's play, even on that one court," she said.

"That would have been massive."

The centre was a finalist in two categories the Urban Development Institute of Australia (UDIA) NSW Crown Group Awards for Excellence in Urban Development 2020.

The South Coast Register has also been told of another instance where water flooded under the fire exit doors on the western side of the complex, facing Artie Smith Oval.

It is understood on that occasion, water flooded the complex with storage areas off courts two, three and four being inundated, causing significant damage to items stored inside.

The water apparently also got underneath the complex's wooden playing surface, closing up expansion joints, which will mean the floors will now have to be fixed.

That could mean the closure for up to two weeks next term, which would throw various sporting organisations' competitions into chaos.

Questions about whether the drainage system of the western side of the complex were adequate, were answered with: "Routine annual maintenance is proposed for the court surface, to be scheduled in consultation with facility users to minimise impact on regular sporting activities."

Barrengarry Conference weekends were previously "good earners" for the Shoalhaven Basketball Association when staged in the old Tigers Den.

With the new complex, canteen takings are retained by council, which runs and staffs the centre, and while the local association was able to run a barbecue, that didn't even cover the cost of hiring the courts for the event.

Questions have also been raised about the future of Shoalhaven Basketball's former stadium the Tigers Den which is now sitting vacant and unused, alongside the new complex.
