A $1250 one-off payment for Queensland public servants won't provide the economic sugar-hit state treasurer Jackie Trad intends, an economist says.
More than 200,000 workers - the bulk of the Queensland public service - will receive the payments on top of annual CPI increases for pay agreements finalised for the three-year period from March 2018.
Ms Trad said the money is in response to Reserve Bank of Australia calls for governments to aid stimulation in the face of capped public sector wage growth.
"The offer of a one-off payment will provide this additional economic support while maintaining the budget balance," Ms Trad said.
The move will cost Queensland about $250 million and most of that money is destined for bill and credit card payments, according University of Queensland economist John Mangan.
"People will pay debt off. It'll do nothing at all," Prof Mangan told AAP.
"That's what always happens when you get these one-off income jolts.
"If it were a permanent pay rise, that would be a completely different thing."
Senior executives and senior officers will not receive the payment, the government said, but nurses and midwives, teachers and administration workers are among those to benefit.
The LNP state opposition and business sector have labelled it a taxpayer-funded bid for votes.
"Any pay increases should be linked to better performances, whether they be in our hospitals, our schools or public transport," LNP deputy leader Tim Mander told reporters on Sunday.
