Police officers in the ACT are already subject to three oversight bodies, the Australian Federal Police Association says, making it both unnecessary and unfair for them to also be subject to the ACT's new integrity commission.

Throughout last year's debate in the lead up to the commission's introduction, both ACT Policing and the association that represents its officers argued they should not be subject to the new local watchdog.

Chief Minister Andrew Barr wrote to both Prime Minister Scott Morrison and former prime minister Malcolm Turnbull, requesting for changes to federal laws to allow local police to be included.

ACT Policing is a branch of the Australian Federal Police, contracted to the ACT government for local law enforcement, which means its officers can't answer to the territory's commission.

The bill for the commission passed in November with an amendment that would allow ACT Policing to be included a year after the commission starts operating in July this year, to give time for the federal government to get on board.

Now Australian Federal Police Association president Angela Smith has called for ACT Policing to be overseen by the new National Integrity Commission, in the same way the local force is covered by the Australian Commission for Law Enforcement Integrity (ACLEI).

"The National Integrity Commission, the federal body, will probably expand the remit of ACLEI and it should boost that, so ACT Policing will still come under the National Integrity Commission. We're federal government employees, we're not ACT government public servants," Ms Smith said.

She said if ACT police officers were covered by the ACT commission, while other AFP officers were covered by its national counterpart, it would create a double standard for officers with the same employer.

"There could be multiple investigations on foot for ACT Policing which is putting them under an extra level that the rest of the AFP is not under and that's really unfair," she said.

"ACT Policing are not employed by the ACT government, they are all employed by the AFP. They're federal government employees, you can't carve out ACT Policing just for the benefits of an ACT integrity commission."

The union also dismissed claims from Chief Minister Andrew Barr that the federal law enforcement commission currently watching over Canberra's police wasn't communicating enough with the territory government.

"It's a contracted service, they're AFP officers, they're employed by the federal government. That's almost like it's dipping into the detail it doesn't really need to dip into," she said.

ACT Policing currently provides reports on complaints to the ACT government twice a year, in line with the purchase agreement. The next report to go to Minister for Police Mick Gentleman is due next month. A spokesman for ACT Policing said verbal briefings are provided from time to time, as well as a professional standards summary provided to the minister periodically, noting any trends or developments.

In 2017, ACT Policing promised to share more details of misconduct and corruption investigations to head off the government's attempts to include the force in the new watchdog's remit.

Corruption allegations rose steeply in ACT Policing in 2017-18, with 19 complaints made compared to nine in the year before, according to the force's annual report.

Three corruption complaints were found not to be established, two weren't proceeded with under discretionary powers and 27 complaints are yet to be finalised, including those brought forward from previous years.
