Playgrounds, skate parks, water fountains and a range of other public facilities have been closed in response to the COVID-19 pandemic.
Horsham Rural City Council Community Services Director Kevin O'Brien said the closures affected all public playgrounds in the municipality.
All non-essential recreational places such as public barbecues, outdoor exercise equipment, sports clubrooms and community halls are now off-limits.
"No-one wants to introduce such widespread measures, but in these unprecedented circumstances they are necessary," Mr O'Brien said.
"By their nature, these facilities encourage congregations of people in large numbers or enclosed spaces, and that's something we all must avoid at the moment."
Under the closures, playgrounds and other facilities with fencing will be locked, with electrical supply switched off for public barbecues.
Signs will be erected at other open playgrounds, advising of the closure.
"We can't physically shut off every playground and other facility that falls under these new arrangements, but we urge the community to take heed of them, for everyone's sake," Mr O'Brien said.
Shared pathways, boat ramps, bike tracks and open green space will remain open, with social distancing.
"We will continue to review the situation and take advice from the State and Federal Governments, and make decisions accordingly," Mr O'Brien said.
"Obviously, the aim is to get these facilities reopened to the community as soon as possible, but right now the absolute priority is public health and reducing the spread of COVID-19 in our community."
