I think it will prolly depend on where the hearing takes place, if it's in the country then he's in big trouble.
Not necessarily
Recently in a well known SE Qld country town, a young guy was at work when police with a warrant arrived at his house to bust him. Due to a tip off, they were expecting to find a small marijuana plantation. They did.
However, unbeknown to the guy at work, a guy who’d recently moved in had decided to do a cook up. As the cops entered the isolated bush house, the cook turned, saw the cop, and dropped a flask on the bathroom floor. It smashed with contents splashing over the bathroom floor. Also found in the bedroom of the guy at work, were three items of interest: a sawn-off 12guage, a semi automatic rifle, and a crossbow.
The house was cordoned off and a Haz-chem team brought it to clean up.
A lengthy interview followed aimed at determining whether the guy at work had any prior knowledge of the speed. It was decided he didn't and he wasn't charged with the speed offences.
His conservative parents (old friends of ours) spent a frantic month arranging legalities and references.
In the end he was fined $2,000 with no conviction recorded. If this had of happened in the city I’m sure all efforts would not have kept this 21 year old out of jail. But in a town where almost everyone owns a gun and dope is common, this is probably close to the norm.
