Since 1995, more than 350 clubs across NSW have closed, with Bulli and Port Kembla bowling clubs included in the Illawarra's casualties.

"We diversified our services to offer accommodation, we focused on quality but affordable food and we've renovated to remain relevant; it's about doing all the little things right," Mr Kipp said.

"Having community ties is crucial and we have partnerships with over 40 groups and sporting teams."

Aged-care provider Warrigal has signed a deal with the Warilla club in recognition of its mutual interests.

In the reciprocal arrangement, Warrigal will pay the bowling club to promote Warrigal's aged-care services to the club's 20,000-strong membership.

Warrigal will promote the bowling club to its 4500 clients in return.

Warrigal chief executive Mark Sewell said the bowling club attracted the partnership due to its focus on providing services to the region's growing aged population.

"While other clubs have taken a shift to catering to younger demographics with loud music, bands and drinking competitions, Warilla bowling club is aware of its older members," he said.

The 2011 Illawarra Shoalhaven Medicare Local profile predicts a 40.2 per cent increase in people aged 65 and over by 2021, based on current demographics.

While declining to specify how much money was exchanged, Mr Sewell said shared philosophy rather than financial details was the important part of the deal.

"We're both non-profits who have worked together for decades and one of our key goals is to make sure residents remain connected and clubs are a great place to connect," he said.
