The park is an intact example of a group of pools in natural water that were developed as features around Victoria early last century.

It played a part in the development of swimming as a sport in Victoria and was often a venue for major regional swimming carnivals in an era before artificial and Olympic pools became common place.

The park's diving tower, wading and toddler pools, entrance gateway and footbridge have all been included on the heritage register.

The listings means the park's structures will not be altered, except for maintenance work that enables the continued use of existing facilities.

Chairwoman of the Heritage Council Chris Gallagher said the entire park was of historical significance to the state of Victoria.

Ms Gallagher said the amended registration included a range of permit exemptions.

"Permit exemptions are intended to allow works that do not affect the historic fabric of a place to be completed without a heritage permit," Ms Gallagher said.

"However, we advise people responsible for the park to always consult with the State Government agency Heritage Victoria before proceeding with any works."

The Victorian Heritage Register was established under the Victorian Heritage Act 1995 and provides the highest level of protection for heritage places and objects in Victoria.

The Heritage Council is an independent statutory authority that decides what places and objects are included on the Victorian Heritage Register.
