Magistrate Simon Brown activated two separate suspended sentences of two months for evading police in March, 2018 and added a three month sentence from December last year.

Bradley David Towns also pleaded guilty a raft of offences including possession of firearms and ammunition, burglary and stealing and possession of stolen property.

He has an eight month jail sentence hanging over his head unless he successfully completes a drug treatment order.

Mr Brown said an evading police charge in aggravated circumstances in 2018 which Towns drove at up to 190kmh on the West Tamar highway was one of real seriousness.

The suspended sentences needed to be activated to fulfil the need for general deterrence.

"Those were very serious examples of aggravated evade which was combined with reckless driving which put police and the public at real risk," Mr Brown said.

Three months jail was added for a charge of evading police in December 2019 which was aggravated by the fact of him being a disqualified driver.

Mr Brown said that Towns firearms' offences were "frankly concerning".

"The nexus between guns possession and drugs is a frequent one and you have twice been in possession of a silencer last year," he said.

"Your prior history of drugs and firearms matters in 2017 is a concerning matter."

Towns was disqualified from driving for 18 months.
