ANTI-URANIUM chants "export Newman, not uranium" outside the Queensland Government's executive building on Monday morning went unheard by the people they wished would hear them most.

The Newman Government's Cabinet, which usually meets at the George St building, met in Kedron for a disaster management briefing instead.

Wilderness Society campaign manager Tim Seelig said Cabinet's decision last week to allow uranium mining in Queensland had united environmentalists, Aboriginal advocates, social justice groups, unions and many other groups in the state.

He said groups had joined forces to "greet them with a very clear message that Queenslanders are strongly opposed to uranium mining".

Mr Seelig said a disaster management meeting was a good place to be because this backflip would result in disasters.

"They'll need emergency services if they're going to mine uranium," he said.

"Uranium mining itself is toxic, dirty and dangerous.

"There is no clean way of mining it, no clean way of transporting it, no clean way of using it.

"From start to finish it's a disaster.

"There is nothing good about uranium mining, it doesn't create many jobs, it doesn't generate a lot of money.

"It just creates a lot of heartache, misery and environmental social disasters."

Overnight, vandals spraypainted the word "tyrant" and nuclear radiation symbols on Premier Campbell Newman's Brisbane electoral office.

Mr Newman told reporters uranium mining would result in more jobs and investment in Queensland.

He said he would not abandon the move or be intimidated by such acts.

Queensland Nuclear Free Alliance campaigner Robin Taubenfeld said the protestors wanted to send a firm signal to the Newman Government.

"We will be a force to reckon with every step of the way as the state and industry attempts to open uranium mines in this state," she said.

Ms Taubenfeld said she would not condone vandalism but she could understand why people were frustrated by the back flip and lack of democratic process.

"Uranium mining in this state would leave our land and our waters scarred and scorched in perpetuity," she said.

"An act of painting on a building, that can be washed off, the legacy of toxic uranium will be ongoing forever."
