ACT Policing saw a 342 per cent increase in use of force reports in relation to Tasers compared to the year before, from 45 reports up to 199 in 2017-18.

The number of times a police officer used discharged the weapon without authorisation also rose dramatically, from one instance to 10 instances the 2017-18 year.

Overall use of force reports decreased in 2017-18 by about 8.5 per cent, including the use of batons (down 53 per cent), pepper spray (down 24 per cent) and handcuffs (down 17 per cent).

The report suggests the increase in Taser use of force reports could be attributed to more police officers being issued the weapons. A rollout over this year and into next will see an extra 281 Tasers in use.

As at November last year, there was a shared pool of 94 Tasers.

The ACT Coroner's Court will hear an inquest into the death of Anthony Caristo, who died after being Tasered by police at his Waramanga home on November 1 last year.

"Use" in a use of force report includes drawing and aiming the weapon, not just firing it.

The annual report shows reports of alleged corruption breaches have also doubled since 2016-17, with 19 matters reported in the last financial year compared to nine in the year before.

The allegations of corruption were referred to the Australian Commission for Law Enforcement Integrity.

Police officers have also increased dobbing themselves and their colleagues in for conduct breaches, with the internal complaints making up a total of nearly 40 per cent of all complaints received.

But in 2017-18, 73 per cent of all conduct breaches were not established, compared with 57 per cent of breaches the year before.

There has also been an increase in established breaches, from 31 to 62 in the last financial year.

But the report notes the cause of the increases was not fully understood, and that police were working with Professional Standards to analyse the trends and identify any underlying causes.

ACT Policing's controlled operations annual report shows undercover officers bought guns and ammunition in a series of controlled operations, however made no arrests and laid no charges as a result.

In five controlled operations, four of which went ahead, police bought eight firearms and ammunition. They purchased six firearms during just one of those operations.

Analysis confirmed the guns were stolen though no charges were laid.

But police did seize 1289 firearms in the 2017-18 financial year, including the firearm amnesty, 1515 illicit drug seizures and more than $13 million in criminal assets and proceeds of crime.

ACT Policing's anti-bikie gang arm Taskforce Nemesis laid 107 charges related to gang activity, 93 raids and seizing 28 guns from gang members and associates.

The ACT government paid ACT Policing $158 million for delivery of policing services in 2017-18.

The report also notes the impact of a rising population on policing, saying that in five years there had been a 30.8 per cent increase in calls requiring urgent police help.

Overall authorities received 29,291 triple-0 calls, police took 1050 intoxicated people into custody and attended 2697 family violence incidents, according to the report.
