The cost of renting space for Queensland’s ministerial office workers has doubled since moving to the privately owned, 260 meter 1 William Street, or as some know it, ‘Big Willy.’

The building was commissioned by the former Newman LNP government, and was engaged in a 15-year agreement to pay more than a billion dollars in its rent.

The Palaszczuk government said it had to fill the building with 5000 public servants as the private sector was not willing to pay the high rent prices resulting in higher costs to taxpayers.

The LNP has argued it was built at no cost and facilitated Queen's Wharf, which created jobs.
