Ms Petrovich said Mr Madden in Parliament last week refused to acknowledge her request to meet landowners.

"The minister does not know, or does not care, about these people," she said.

"The simple fact is that urban development is many years away. Yet if a farmer wants to retire now, he or she will have a liability of $95,000 - even if the land sells for much less."

Under the proposal, landowners will have to pay a $95,000-a-hectare levy to the State Government when they sell their land.

Ms Petrovich said it was obvious the Government was interested only in a cash-grab.

"Property owners who now fall under the new urban growth boundaries will be stripped of their fundamental rights of deciding where they can live and when they can move on," Ms Petrovich said.

"With this pending tax liability, all landowners in these areas have, overnight, become a major credit risk through no fault of their own.

"This financial crisis for many landowners lies 100per cent squarely on the shoulders of Mr Madden.

"The very least he could do is sit down with them and listen to their concerns."

A spokesman for the minister said the request for a meeting was "under consideration".

He said it was the Government's job to balance the need for new homes and the growing population.

The spokesman said the Government was engaging with the community to get the balance right by holding information sessions with community groups and calling for submissions about the draft urban growth boundary report.

"The Government has put its planning vision on the record ... the Liberal-National Party have no policy ... and no clue on how to protect our livability and manage growth."
