Premier Peter Gutwein last week announced the legislation would be introduced to Parliament in May.

The government has said the legislation would provide confidence in the community, but many think there will be adverse implications.

In 2017, the government announced a plan for the legislation, but it was later withdrawn.

Planning Minister Roger Jaensch said the assessment process would draw from and improve upon the existing Projects of Regional Significance process.

"It provides a more clearly defined process, with set time frames, and co-ordinates a greater range of permits and approvals," he said.

"It will provide for the assessment of development proposals of significant scale, impact or complexity, including projects that cross municipalities or require assessment under multiple acts."

However, the Tasmanian Conservatory Trust's Peter McGlone said the proposal makes a mockery of the Tasmanian Planning Scheme, with section 60(l) of the major projects legislation setting out the ineligibility criteria.

"Virtually any development big or small could be declared a major project," he said. "Unlike previous versions the current draft does not identify any specific type of development that is ineligible and our legal advice is that the ineligibility criteria are so hard to meet that virtually no development would be ineligible."

The government said not all projects could be considered major and could not be taken off a council, because the assessment process was developed for projects that are significant in terms of their impacts, complexity and importance.

A minister may refer a project for consideration, but it is still be required satisfy the eligibility criteria before it can be declared as a major project, a spokesman said.

"Once the minister declares a major project, the actual assessment is undertaken by an independent expert panel, specially convened by the Tasmanian Planning Commission, in conjunction with statutory regulators," Mr Jaensch said.

"The Major Projects Legislation will provide confidence to the community that complex development proposals will undergo rigorous assessment by independent experts with opportunities for public input."

Mr McGlone said 28 days advertising is not enough.

"You've got 28 days to work out what what your position is, find experts that can represent you in the hearings, lawyers, potentially, and then turn up in the hearing, and have your say that's, that's it that's the all you ever have," he said.

Mr Jaensch said the consultation period was twice as long as that for a standard development application.
