Labor housing spokeswoman Alison Standen said the proposal also fails to address important concerns surrounding traffic, and the services and infrastructure needed to support a development of that size.

The government's rezoning of the land, located south of Hobart, under new laws introduced in response to the state's housing crisis last year, has been met with a variety of opposition.

Under the new legislation, government-owned land can be rezoned by notifying bordering residents, with a reduced time to comment of 14 days, and it bypasses councils and planning authorities.

The land was rezoned to facilitate the building of a mix of 450 social, affordable and private homes.

The government said 15 per cent of these homes will be designated as social housing.

A meeting held last week by Planning Matters Alliance Tasmania saw over 300 residents turn out to voice their concerns about the fast-tracking of the proposal.

Neither Premier Will Hodgman or Housing Minister Roger Jaensch attended the meeting.

"We have a situation where the Premier has failed to front a community meeting of more than 300 people to discuss the nature of the proposal and a range of concerns the community has," Ms Standen said.

"We are talking about a proposal to create an effectively a new neighborhood.

"Locals are being kept in the dark about what the government's commitment to a master plan will look like at the end of the day in relation to critical facilities like playgrounds, cycle paths and open space."

Mr Jaensch said the community would be able to have its say when development applications go before councils.
