Basketball and netball competitions are to start on April 28, with work to replace the roof scheduled to begin on June 1 and be completed at the end of September.

During the next two school terms, basketball and netball competitions will begin at the stadium at the end of April and then continue at other venues from the start of June.

Men's basketball and women's netball will be played at the Illawarra Sports High School, Berkeley from June 2, while mixed, junior and high school basketball will be played at the Illawarra Christian School's Tongarra Campus during the same week.

The Pre-School Skills 4 Life will be held at Centenary Hall, Albion Park from June 4.

Shellharbour Mayor Marianne Saliba said problems with the stadium roof had affected the availability and the reputation of the facility for a number of years.

"We look forward to having a sound, watertight venue that our community can rely on to be open in all kinds of weather," she said.

"Staff have secured other locations for sports groups so that competitions can continue with as little disruption as possible."

In February, the council resolved to push ahead with plans for the new $1.45 million roof over Shellharbour City Stadium, despite concerns the stadium could be demolished to make way for the Albion Park Rail bypass.

User groups say problems with the leaky roof date back to when the complex opened in 2000, although the council has previously said the leaks were first noticed in 2005. In 2012 and 2013, the indoor stadium had to be closed on 55 days due to wet weather.
