The reliability of a witness who was duped into allegedly being the getaway driver for two robbers has been questioned in court.
In his closing address, crown prosecutor John Ransom said driver Jake Rowe-Brown's evidence was corroborated with police statements and CCTV footage from the Plough Inn, but defence lawyer Patrick O'Halloran questioned the former ice addict's reliability.
Mr Rowe-Brown took the stand during Billy Galvin Gordon Riley's Launceston Supreme Court trial.
Mr Riley has pleaded not guilty to attempting to rob two French tourists with Brereton James Jones while armed with a replica gun and pogo stick in October 2017.
Jones has pleaded guilty to the crime.

On the day of the robbery, the court heard Jones called Mr Rowe-Brown and said: "no mucking around, I need a lift".
When Mr Rowe-Brown picked up who he said was Jones and Mr Riley from a South Launceston address he saw Jones put a pogo stick against the house.
The police officer who found the pogo stick also told the court it was against the house.
It was alleged Mr Rowe-Brown drove the men to the Plough Inn.
CCTV of the pub's carpark was played to the jury, with Mr Ransom saying it showed Mr Riley wearing the same "thug life" singlet described by witness Chantel Dance.
The footage was "very powerful, independent corroboration" of what Mr Rowe-Brown told the court, Mr Ransom said.
Defence lawyer Patrick O'Halloran told the court the key aspect of the Crown's case was Mr Rowe-Brown's evidence, but he was a young man at the time of the crime and addicted to ice.
Mr Rowe-Brown told the court on the night of the robbery he dropped Mr Riley at his Kings Meadows house but, after being challenged by Mr O'Halloran multiple times, he conceded it didn't happen.
"He can not and has not given accurate evidence," Mr O'Halloran said.
The trial before Chief Justice Alan Blow continues.
