Homeless protesters entering their third week camping at Melbourne's City Square say they will not move until housing is provided for all people sleeping rough across Melbourne.

The group is also pushing for a 24-hour drop-in centre to be created in Melbourne CBD.

"This has literally become a 24-hour community centre," Lisa Peterson, who has been sleeping in the square for two weeks, said.

"I'm not sure how it's going to be moved on. People are coming through at two o'clock in the morning and getting pants, blankets, coats, it's keeping people's spirits up and giving people somewhere to go.
