The Queensland government won't seek a mandate to sell off public buildings in Brisbane, because they're not considered big-ticket assets.

The Liberal National Party went to the March election promising not to sell off public assets without taking any plans to the next election.

But Treasurer Tim Nicholls today clarified the government's position, saying the pledge applied only to "major" public assets.

"That is, things like the power generators, the poles that transmit the power, those assets," he told reporters.

"Those major government-owned assets."
