Aboriginal rights protesters have been given an ultimatum to leave Melbourne's Kings Domain within a day or face charges.
Aboriginal camp spokesman Robbie Thorpe has threatened to hold a peak-hour city protest if they are removed forcibly.
Lord Mayor John so has tried to negotiate a deal with the protesters during the past three days.
The group, which has lived at so-called Camp Sovereignty since last month,says authorities have already decided to move them on.
Mr So says Melbourne is willing to discuss with traditional owners further ways to recognise the cultural significance of the Kings Domain site, once it's been vacated.
