The sale of swathes of public land across Victoria has been labelled a cash grab and threat to the future of treaty negotiations with the state's indigenous people.
Prominent Aboriginal woman and former Greens MP Lidia Thorpe has slammed the Victorian government for preparing to sell more than 140 public sites.
"This mass sell-off of surplus Crown and public land is a betrayal of the treaty process," the Gunnai-Kurnai and Gunditjmara advocate said on Thursday in a statement.
"Land is crucial in settling treaties between the Victorian government and the first peoples of this land, but how can we negotiate for this public land if it has all been sold?"
The warning accompanies government data revealing 141 public-owned properties, totalling almost 2660 hectares of land, are being prepared for future sale.
"Each site is being assessed for market readiness which may include processes such as rezoning and remediation," the Treasury and Finance website states.
"The time it takes to market each property can vary depending on the type and nature of market readiness activities and can take several years."
The properties have been declared "surplus to requirements" and offered for sale.
The land should be kept for now, said Ms Thorpe, who is a candidate for the First Peoples' Assembly to determine the framework for treaty.
"Our homes and land were stolen from us," she said.
"Through treaties land must be restored to first peoples to ensure that we can build homes for all of us, so we can establish healing places and cultural centres to celebrate our culture, and so we can have a say over the management of our natural places."
The Greens plan to move a motion in parliament calling for a moratorium on private sales of surplus Crown and public land until treaties are negotiated with Victoria's traditional owners.
Voting is open for representatives to the First Peoples' Assembly, which is designed to help determine the framework for a treaty, bringing agreements with the government closer in Victoria.
"A good government would put the interests of communities first. Public land should be kept to meet public needs, not be sold off to prop up the government's bottom line," Victorian Greens leader Samantha Ratnam said.
The Greens want the government to use the land to address a shortage of 164,000 affordable public housing units.
