Work is nearing completion on the $69 million aquatic, arts and leisure centre in Batemans Bay, known as the Bay Pavilions.
Eurobodalla Shire Council's project coordinator of the Bay Pavilions, Chris Tague, said an official opening would be held on April 28.
The centre then open to the public in June.
The centre - on the Princes Highway opposite McDonald's - includes a cafe, performance auditorium, art gallery, 25-metre indoor pool, learn-to-swim pool, indoor and outdoor splash parks and four waterslides ranging from 56 metres to 64 metres long.
It replaces an existing 50-metre outside pool and privately-run Batemans Bay Mini Golf.
The centre was funded mostly by $51 million in grant money from the state and commonwealth governments, the remainder financed by the council.
Mr Tague says he expected use of the facility straight away, even the waterslides, from June, with locals excited to have an indoor pool.
He said some people had been worried the slides were too small.
All were more than 800mm in diameter and designed for adult use, as well as children, Mr Tague said.
"There will be height restrictions," he said.
Mr Tague said the performance centre, which could seat 350 people, would be used for anything from pantomimes to ballet to rock bands.
He expected Canberrans to be using the centre as well.
"I hope so," he said. "The feedback we've got is that being able to see a particular performance will be another excuse for them to come down for the weekend."
Mr Tague said the owners of the Batemans Bay Mini Golf business were paid out by the council after they declined to lease another site.
The council decided the previous 50-metre pool was "not meeting the needs of the community" open for only half the year.
The community wanted a 50-metre pool built in the new centre but the council acted on advice that it would be more expensive to run and build.
A 25-metre pool allowed for a therapy pool and a learn-to-swim pool to be also included in the new facility.
"Council has no plans to increase rates to pay for this project," it said.
"Council is committed to building an affordable aquatic and arts facility that meets the needs of the community and does not require a rates increase to pay for it."
