Queensland public sector unions are linking a high amount of early voting in the upcoming state election to dissatisfaction with Premier Campbell Newman.

The unions say public servants are voting to send a message to the man who betrayed their trust.

The Electoral Commission of Queensland has received more than 22,500 votes since pre-poll voting opened on Monday.

Together Union secretary Alex Scott has told the AAP that many of those were public servants wanting to get in early.

“We know there'll be more job cuts to come if (Premier) Campbell Newman gets re-elected as he seeks to privatise disability services, corrective services and parts of our health and education system,” Mr Scott said.

The union is keen to remind Queensland voters of Mr Newman's pledge before the 2012 election that public servants had nothing to fear from the LNP.

After getting into power, he slashed 24,000 government jobs.

“It's vitally important that Queenslanders judge Campbell Newman by his track record and not by his election promises.”

Similar criticism of Mr Newman’s short-term memory came from Fairfax Media outlet The Brisbane Times this week.

It has run a story pointing out a speech by Mr Newman in 2011, in which he questioned the need to continue mining so much coal. 

“It would be a great idea if rather than digging up huge piles of black stuff out of the ground a few hundred kilometres north of here to keep those lights on, perhaps it would be better in the long term for our children, our grandchildren and the generations to come that we set things up a bit differently,” Mr Newman – as Brisbane Lord Mayor at the time – said in the Australia Day address.
