Aboriginal protesters opposing a development at The Block in Redfern have lost their court case against a possession order for the land.

The Supreme Court today ruled in favour of the Aboriginal Housing Company (AHC).

Members of the Redfern Aboriginal Tent Embassy have been present on the site for more than a year.

The case will return to court on Thursday to consider when an eviction order should be enforced.

The Aboriginal Tent Embassy was established in Redfern more than a year ago by Wiradjuri elder Jenny Munro, who has been camping at the site since May 26, 2014.

Ms Munro has been fighting the development for more than a year and said her campaign was not over.

"[The case is] another one of the fronts of the many battles we've had to front for over 227 years," she said outside court.

"When I stop breathing, then I finish fighting."

The Tent Embassy is made up of a small knot of regular residents, who were served with two eviction notices this year, and a passing parade of supporters.

These have passed without action being taken against the protestors.

In June, the protesters insisted they would not move until the land owners, the AHC, prioritised affordable housing for Indigenous people on the site.

The AHC insisted the affordable housing could only be completed after a commercial development including retail outlets, offices and student housing has been completed to fund the community housing.
