But the exact figure around the allocation of an additional 125 officers is still unclear with the government failing to clarify if the 15 officers earmarked for Launceston includes the four recruits who started in April.

Police Association of Tasmania president Colin Riley said it had raised concerns about staffing levels in Launceston with Tasmania Police and successive state governments for decades.

"In simple terms, without enough police numbers on the streets of Launceston, the people of Launceston ... are not safe enough," Inspector Riley said.

The association is calling for 31 of the 125 new police recruits to be allocated to the Northern District, which includes the North-East of the state from Launceston to George Town and St Helens, with 20 of those officers to be posted to the Launceston station.

The Examiner sent questions to Tasmania Police and Police Minister Mark Shelton's office about how many of the additional officers had been earmarked for the North and, more specifically, Launceston, but a government spokesman responded for both.

The spokesman for Mr Shelton said factors considered as part of the allocation model included population and demographic, capability, crime trends, safe staffing levels and policing demands.

"A further nine police officers will be allocated to Launceston from this week's graduation," the spokesman said.

Today's recruit graduation means 40 of the extra 125 positions have been filled.

Tasmania Police's 2018-19 Corporate Performance Report revealed an almost 23 per cent increase in offences in the Northern District.

Inspector Riley said proactive policing was only possible if front-end officer numbers were sufficient.

"In Launceston, our members' time to undertake these important tasks has been greatly reduced for a number of reasons," he said.

"Launceston has had a large number of "difficult" serious crimes to investigate and resolve which takes greater resources away from proactive intervention strategies to reactive resolution strategies."

Inspector Riley said the allocated strength of police numbers in Launceston was insufficient, but the effective strength or "boots on the ground" was even lower.

"The effective strength doesn't include those on sick leave, workers compensation, maternity/paternity leave or educational courses," he said.

"Our members increasingly undertake the primary functions of other government agencies, as those agencies' capacity to respond outside working hours diminishes."
