Attorney-General Elise Archer tabled the bill in the House of Assembly on Thursday.

"The bill I have tabled amends the act to ensure there is a right to external review by the Ombudsman of decisions of Ministers and Ministers' delegates as to whether or not information should be provided under the act," Ms Archer said.

"Both this government and the previous Labor-Green government had held the view that RTI decisions made by a ministerial delegate were reviewable by the Ombudsman. However, a recent Supreme Court decision clarified that this is not the case."

Ms Archer said the bill would amend the act without unintended legal consequences.

"The responsible action the government is taking to amend the act, together with additional funding provided to the Office of the Ombudsman in this year's Budget, demonstrates the Government's ongoing commitment to improving the openness, accountability and transparency of the operations of government in Tasmania," she said.

A Greens spokeswoman said the party would be looking at the bill closely to see what improvements can be made.

"We want to see the strongest possible Right to Information laws in Tasmania," the spokeswoman said.
