When Daniel John Pritchard takes drugs he "acts impulsively" like he did one morning in August when he exposed his genitals to a woman walking at Henley Lake.
But what was most concerning about the incident was he had a loaded rifle nearby, Judge Barbara Morris said at sentencing for the 43-year-old recently.
Pritchard previously pleaded guilty to indecent exposure, possession of cannabis and unlawful possession of a .22 and ammunition.
Prior to sentencing he also pleaded guilty to defrauding a former employer by using a work fuel card he retained at the end of his employment, to pay for $821.38 fuel for his own vehicle.
The labourer had been remanded in custody with interim name suppression for a psychiatric report.
