Officer In Charge Sergeant Darryn Morris said while the case was unusual, it was no less serious.
"Due to the fact it is a petrol engine (the esky) falls under the ambit of a motor vehicle under the Traffic Act," Sgt Morris said.
"Some people aren't aware that if they're riding a wheeled object, the footpath is also deemed a road under Queensland legislation."
"It is a serious issue due to one, the amount of alcohol he had on him at the time and two, in relation to those using these motorised devices that can cause serious injury to themselves or other people."
What the esky contained:
• 10 tallies of beer
• Two bags of cask wine
• Up to six cans of bourbon
