A YOUNG Gympie man who provided police with an easy catch on April 19 asked Magistrate Maxine Baldwin on Monday if he should try to be smarter in future.

The response drew laughter from some in the public gallery as Patrick Wass Davis, 22, left the courtroom, at the conclusion of his case.

Mrs Baldwin fined Davis $750 when he pleaded guilty in Gympie Magistrates Court to possessing cannabis, seeds and utensils.

The court was told police were able to see the prohibited items through Davis's open front door when they knocked on April 19, seeking his help in solving a burglary nearby.

Police had gone to Davis's Rifle Range Rd home at 12.05am, looking for possible witnesses to the burglary.

Seeing the front door half open, police knocked and called out "Police" in their attempts to rouse residents.

They saw a water pipe and a bowl with a small quantity of cannabis, less than 1gm.

A short time later, Davis returned to the house after helping his brother, who had been a victim of the burglary.

Mrs Baldwin warned him of more serious trouble ahead and would end up in jail if he continued to use cannabis.

"I like the weed," he said in reply.

"Well, you're going to have to move to another state," Mrs Baldwin said.

"Go to Canberra."

Fining Davis $750, she warned that this was "probably the highest level" of fine which could be imposed, before other penalties were imposed.

"If you're going to live in Queensland, you have to find something you like better than marijuana," Mrs Baldwin said.

"Or just be smarter?" Davis asked, before leaving the courtroom.

In another matter before the court on Monday, Brooke Rose Leonard, 21, of Green Valley Dve, Rainbow Beach, pleaded guilty to possessing cannabis and a pipe, as well as scissors and an electric grinder used to prepare the drug.

She was placed on a $550 good behaviour bond for five months for the April 15 offence.
