The expansion includes an occasional care service to replace Ballarat Council's occasional care service moving to the site following the sale of the former centre in Armstrong St in June.

Long day and short term care have been integrated, capacity increased and an extra 45 kindergarten places created.

"Ballarat families will reap the benefits of this upgrade and local kids will get the best out of this upgraded kinder," said Wendouree MP Juliana Addison.

With state government and council contributing to the expansion, the centre has been designed as a one-stop shop for families with maternal child health services also housed in the Steinfeld Street building.

"The introduction of occasional care co-located with long day care provides increased choice and flexibility for families," said mayor Samantha McIntosh.

"The upgraded site has also allowed for the relocation of other City of Ballarat Family and Children's Services staff to give greater access to on-site information about early childhood services."
