Prahran Square is a large outdoor public-event precinct in Cato Street with nine zones available by application. Stonnington Council describes up to 3,000–5,000 people for the square as a whole, with mains water, three-phase power, lifts, toilets and accessible features. Individual zone limits and event permits need approval. Important booking conditions: 5,000 is an upper bound for whole-site events, not automatic approval for any zone. Event applications, council plastic-free policy and public-space rules apply.
