Ipswich mayor Paul Pisasale says an investigation by Queensland’s corruption watchdog will show he hasn’t done anything wrong.

The mayor of Ipswich has called for clearer electoral donation laws while insisting the Queensland corruption watchdog will clear him of any wrongdoing.

The state government said in June that allegations Paul Pisasale had received up to $150,000 in undeclared donations had been referred to the Crime and Corruption Commission (CCC).

On Friday, the commission confirmed it would investigate unspecified allegations relating to the mayor.

Mr Pisasale says he has not been made aware what allegations are being investigated but will co-operate fully with the inquiry.

“What I believe is that what I’ve done is right and I can assure that (the investigation) will show that to be the case,” he told AAP.

Mr Pisasale said that in order to stop confusion, the electoral donations system for state and federal governments should also apply to councils.

“At the moment it’s all over the place and it’s all different and I don’t want anyone else to go through what I’ve had to go through,” he said.

“Why don’t they all have the same rules?”

A statement from the CCC on Friday said all allegations should be treated as unsubstantiated until a final outcome is reached.

It added that no further comment would be made while the investigation was under way.

Councillors are legally required to update their register of interests but do not need to declare donations of less than $200 to the Queensland Electoral Commission (ECQ).

It has previously been reported that Mr Pisasale’s election campaign fund, Forward Ipswich, has received more than 30 separate donations worth $150,000 since the 2012 council poll.

Under state laws, a councillor who fails to complete or update a register of interest can be fined up to $9350.

Those who intentionally fail to complete or update a register of interests can be fined up to $11,000 and be disqualified for holding office for four years.
