Queensland’s most powerful public servant has spent more than $2900 on limos but his office says his expenses are cheaper than Labor’s.

The Queensland premier’s director-general has spent more than $2900 on limos and $14,000 on external catering since the Liberal National Party came to office two years ago.

Jon Grayson has chosen to hire limousines instead of taxis on 16 occasions since mid-2012.

His taxpayer-funded MasterCard paid for the services of Hughes Limousines, based at Fitzroy North in Melbourne, and Driven By Limo, based at Yagoona in Sydney’s west, right-to-information documents obtained by AAP show.

The expenses added up to $2906, with one trip costing $380.51 in May 2014.

The documents also showed $14,000 was spent on external catering over a two-year period.

But a spokesman for the director-general said his expenses covering April 2012 to May 2014 were a third cheaper, or about $11,000 less, compared with the last 26 months of Labor’s time in office, when Ken Smith and John Bradley were in that role.

“All expenditure falls within departmental guidelines and is subject to rigorous audits,” he said in a statement to AAP.

“The director-general uses the most efficient and reliable option of quickly getting to and from meetings and this is often pre-booked travel.”

Mr Grayson’s office also received a warning in February 2013 about an overdue bill of $71.65 for milk, asking for payment within seven days.

“We would appreciate your arranging for the account to be settled, in full, by the end of this week,” an email seen by AAP says.

Opposition Leader Annastacia Palaszczuk said the revelations about $14,000 spent on hospitality was outrageous following the sacking of 14,000 public servants in 2012.

“Jon Grayson earns almost $700,000 a year and he sees fit to dip into the public purse for coffee and cake,” she said in a statement.

“This is outrageous and out of touch.”

Mr Grayson has previously been mired in another controversy, relating to his shareholdings.

In May, he divested his shareholding in Gasfields Water and Waste Services, a company with links to disgraced NSW Labor powerbroker Eddie Obeid’s nephew Dennis Jabour.
