Greens leader Meredith Hunter said Mr Quinlan's centrepiece plan to abolish stamp duty and replace it with a ''broad-based property tax'', had been Greens policy for some time, but Canberra Liberals' deputy leader Brendan Smyth said the review would not cut taxes.

Mr Smyth was also critical of the timing of the release of the report.

''The government has had this review for five months, we've had it for five hours,'' he said.

''A lot of the devil is in the detail and coming to an opinion but from what I can see, at the start of this process, we had the highest taxing government in the country and at the end of this government, we will still have the highest taxing government in the country. At the end of the day, it means that the territory taxpayer is going to be paying at least what they are paying now and we have the highest taxing government in the history of the ACT.'' Mr Smyth, whose party did not make a submission to the review process, would not say when the Liberals' would release a tax policy to take to the October territory election.

But Ms Hunter threw her support behind Mr Quinlan's plan.

''It's time that we looked at our taxation system,'' she said. ''We need to ensure that we're going to have constant revenue streams into the future, so this recommendation around moving stamp duty to a land tax, a broader base of tax, we welcome that.

''The territory needs to be looking at this and leading on this because if we left it until there was some sort of nationwide move, we would never get anywhere.

''This was one of the reforms or recommendations put out by the Henry tax review and the Greens supported it since it was part of that tax review.''

Both the ACT Property Council and the Tax Institute also welcome the plan.

''I think the ACT government has gone a long way to at least putting on the table, the need for reform in these areas,'' Institute senior counsel Robert Jeremenko said.

ACT Property Council executive director Catherine Carter broadly welcomed the review, but was unhappy at its endorsement of the controversial ''change of use'' charges. ''The panel observes what the Property Council has been saying for years, that some of the ACT's current taxes are either not stable, do not deliver growth commensurate with the growth in the economy, or are highly inefficient and are unsustainable in the long-term,'' Ms Carter said.
