The Queensland Government has caved in to pressure over a controversial pay rise for state politicians.

The Government has been under fire over the hefty wage hike stemming from a law that links their pay to that of their federal counterparts.

MPs would have pocketed an extra $57,000 a year, with Premier Campbell Newman receiving an additional $118,000.

Acting Premier Jeff Seeney says he is not comfortable with those amounts and says Parliament will revisit the issue.

"Almost inevitably there will be a change, but it can only be changed by the Parliament," he said.

"So between now and when Parliament sits, we will be considering what changes need to be made to produce an outcome that's a little bit more comfortable that what's been produced today."

"We will fix it, but we will do it properly."

Mr Seeney has flagged setting up an independent tribunal to set politicians' pay.

Until today, ministers had defended the pay increase.

A decision allowing the rise was handed down by the Remuneration Tribunal, which ruled the Bligh government's 2009 freeze on MP salaries was unlawful.

Mr Seeney last week announced the rise would be cost-neutral because he was cutting MPs' allowances and reducing the money paid to political parties.

Opposition Leader Annastacia Palaszczuk says Mr Newman's pay rise would have seen him get as much as the US president.

"Every LNP Member has essentially won Gold Lotto," she said.

Together Union spokesman Alex Scott says he wants a guarantee the increases will be overturned, not just reviewed in Parliament.

"The Queensland community is outraged by the Premier's pay rise, they're outraged by the Acting Premier's pay rise," he said.

About 100 union protesters staged a noisy demonstration outside a meeting of state cabinet in Brisbane on Monday.

Independent MP Peter Wellington had earlier said he would not accept the pay rise and instead use it entirely in his electorate.
