Curtly James Hodge, 19, pleaded guilty in the Launceston Magistrates Court on Tuesday to multiple charges in relation to petrol station drive-offs, credit card fraud and resisting arrest.

Along with a co-offender, Hodge used a credit card belonging to another man to buy taxi trips, groceries and alcohol in Prospect on October 22, eight days after he was released on bail for other offences. He then missed three appointments which were conditions of his bail.

He was in the back seat of a Ford Focus on November 20, the day after it had been stolen from an address on Joffre Street, Mowbray. The car was used to carry out petrol station drive-offs at BP on Wellington Street and Woolworths petrol in Kings Meadows.

The car was driven to a fire track behind the Dover Street housing complex in Mowbray later that day and police attended, spotting Hodge nearby.

When attempting to arrest him, Hodge fought back against police and was "thrashing about" when they tried to handcuff him. He was in possession of methylamphetamine and cannabis.

By committing the offences, Hodge violated the terms of a suspended sentence handed down in August last year for firearms offences.

Hodge has been homeless for much of his adult life, the court was told.

Defence counsel Mark Doyle said Hodge presented a complex case for the courts, but his young age meant there was still time to provide the support he needed to turn around his offending ways.

"He had the most difficult of upbringings and really we are seeing the consequences of that upbringing in terms of his behavior and addictions," he said.

"He is a man who still has much time to change his life if he can put in the work."

Hodge will be sentenced in the Magistrates Court on Thursday.
