Nearly 14 months have passed since Redfern's Aboriginal tent embassy was founded on the Block and, with a reprieve of at least another five weeks, its supporters are not leaving without a fight.

As civil proceedings against squatters on the disputed land unfold in the NSW Supreme Court, lawyers for the tent embassy have lodged a complaint with the government over the intentions of the Aboriginal Housing Company, which is pushing for redevelopment of the small but historically significant site.

The AHC was formed in 1973 and, using federal government funding, bought the land bordered by Louis, Vine, Caroline and Eveleigh streets for the charitable purpose of providing housing for Aboriginal people.

But in documents sent to the Attorney-General on May 3, tent embassy protesters claim that the $70 million Pemulwuy Project's plans for a commercial centre, shops, a new gym, accommodation for 154 university students and 62 affordable homes for Aboriginal people do not meet its charitable remit.
