Queensland Premier Anna Bligh on Friday suggested to make some changes on the federal government's proposed mining tax to protect the growing Liquefied Natural gas industry.

It was reported that Santos Limited withdrew its plans to build a $15 billion plant in central Queensland due to mining tax concerns.

The Queensland Gas Corporation explained it will continue to review the impact of the federal government's proposed resource tax on its development project Gladstone liquefied natural gas plant in the central region.

According to Ms. Bligh, a fair deal is a must for the new industries.

“We need to see a package that treats it in a different way than those companies that have been in operations for forty and fifty years, she stressed.

“All of the capital investment is up front.”

Ms. Bligh argues that international companies cannot make decisions easily until they are certain about the costs of their businesses and investments.

A Santos spokesperson said that a 40 per cent tax on super profits will threaten the company's “stable fiscal regime” and calls on the government to rethink its decision on the proposed tax.

Gavin Jackman of Santos Ltd said a decision on its LNG plant in Gladstone will be announced in the middle of the year.

"It will be later than originally expected and that's in part so that we can take the time to understand what this tax means for the project," he said.

Santos and QGC will focus on securing environmental approvals for their development projects and will anticipate a decision by the end of the year.
