Sutherland Leisure Centre's indoor play and water park facilities won't be open during the school holidays, which start at the end of this month.
Sutherland Shire Council is playing it safe and won't reopen all leisure centre facilities until senior staff are confident they are fully compliant with health requirements.
The aim is to progressively open remaining facilities from the start of the fourth school term.
A council spokeswoman said, "to ensure the facilities are fully compliant with COVID Safe measures, there will be no indoor children's play activity or water park facilities available during the forthcoming school holidays at Sutherland Leisure Centre".
The spokeswoman said the council was "keenly focused on protecting the health and wellbeing of patrons and staff attending council facilities, and has taken great care to implement necessary health measures and procedures at all our facilities to guard against the potential spread of COVID-19 in our community".
"In meeting this challenge, council has changed the operating hours at some council operated leisure centres to ensure staff are able to maintain their regular focus on supporting the safety of patrons at these facilities as well as conducting additional COVID Safe practices required to minimise the risk of infection," she said.
"Council is finalising its engagement of additional permanent leisure centre staff, with the aim of progressively resuming standard operating hours across all our leisure centre facilities and having all facilities fully operational within public health order parameters, by the start of the fourth school term.
"Council is working collaboratively with a range of regular user groups and patrons to ensure we can best support them in accessing our leisure centres while still enabling us to adhere to COVID Safe practices and allow social distancing to be observed.
"Additional resources have been implemented to conduct extensive cleaning and COVID marshalling.
"Council wishes to thank all regular patrons of our leisure centres and the wider community for their continued patience as we work towards returning to full operational hours across these much valued community facilities."
