The new head of Queensland's chief corruption and crime fighting body is stamping his authority on the organisation, signalling a crackdown on police using excessive force and vowing to maintain the organisation's independence.

Alan MacSporran became chairman of the Crime and Corruption Commission (CCC) one month ago.

The barrister and former public prosecutor is the first permanent chairman of the CCC in more than two years.

Speaking for the first time since his appointment, Mr MacSporran said he hoped to bring stability to the role and described the organisation's independence as "absolutely critical".

"It has no credibility if it is not independent and able to robustly investigate matters and that under my chairmanship is a focus," he said.

"I'm determined that this organisation be seen to be entirely independent."

Police discipline system in MacSporran's sights

He said his first priority would be to look into the police discipline system, with an emphasis on recent allegations of excessive use of force by officers.

"My impression is that by far the greater majority of serving police officers do their job extremely well in difficult, challenging circumstances," he said.

"It is, however, the few that transgress and behave in the way you've seen depicted in the media recently that have the greatest potential to destroy public confidence in the service and the system generally.

"So it seems to be that the CCC in particular needs to be more proactive and ... if appropriate on occasions, take over investigations and closely monitor the outcome of sanctions that are imposed on occasions for behaviour of that kind."

He said current disciplinary processes allowed for a police officer to be dismissed, but the sanction can then be suspended.

"It seems to me that it is illogical if there is a police officer who has behaved so badly to warrant dismissal to have that sanction suspended and they remain in the force on good behaviour as it were," Mr MacSporran said.

He said he had raised his concerns with Police Commissioner Ian Stewart.

Political donations inquiry on agenda

Mr MacSporran is also waiting for a request for an inquiry into political donations.

The State Government made an election commitment to look into any connections between political donations and the awarding of Government contracts.

The Attorney-General Yvette D'Ath is understood to be writing the terms of reference for a potential inquiry, which the Opposition has already branded as an attempt to politicise the CCC.

Mr MacSporran said the Government was yet to approach him.

"If and when it happens we'll look at it, because our jurisdiction, which is governed by the terms of our act, requires us to look at all complaints that come our way, but we have a reasonably high threshold test to satisfy before we can launch investigations," he said.

"Our definition of corrupt conduct means we have to be reasonably satisfied that the evidence produced to us is capable of amounting to corrupt conduct.

"It doesn't matter who sends it to us, we look at it, apply the same test, if it does amount to corrupt conduct we investigate. If it doesn't we don't."

He dismissed the Opposition's concerns that the inquiry could be a "witch-hunt".

"I can understand entirely the sentiment, but the difficulty is that people should stand back and let us do our job," he said.

"If a complaint comes our way, we will assess it on its merits, independently objectively and thoroughly."
