Bass Coast Shire Council has appointed Aligned Leisure to manage the Phillip Island Leisure Centre and Bass Coast Aquatic Centre from July 1.

Council said the appointment was the result of a competitive tender process, and Aligned Leisure "will deliver inclusive, and high-quality programs both within the facilities and out in the community".

CEO Greg Box said Aligned Leisure is a highly capable, community-focused organisation with a strong track record in facility management and working in community.

"We're excited to partner with Aligned Leisure, leaders in the aquatics and leisure industry, currently operating 46 facilities across Australia," Mr Box said.

Mr Box thanked YMCA Victoria for their years of dedicated service to the Bass Coast community.

"Our priority is to ensure a smooth transition, working closely with both YMCA Victoria and Aligned Leisure to maintain seamless access to our facilities."

Council said staff employed at the centres have been advised and plans are in place to support them through the transition process.

"All members and stakeholders will be contacted in the coming weeks with details about the transition," a council spokesperson stated.
