Anyone thinking of trespassing at Burnie's port this weekend is being warned they risk $5,000 fines.
A Hellyer College student reportedly behind the "Storm the Pile" Facebook event, which urged the public to invade the restricted area, has pulled the event down.
The abrupt cancellation came after it attracted more than 500 people who indicated an intention to trespass on the site on Saturday.
Police say while it was apparently a joke, they'll now have to divert resources to protect the port.
“Whilst the ‘Storm the Woodchip Pile’ Facebook event may have been created and intended as a joke, the content had serious ramifications as it was encouraging others to break the law,” Inspector Adrian Shadbolt said.
“While Facebook events may be intended to be a joke, Tasmania Police take proposed actions that encourage law breaking and trespass seriously. While this specific event has been deleted, I encourage people to be mindful that the action it promoted is illegal and not to participate.”
“Police will have resources where the event was planned, which diverts resources from policing activities to keep the community safe.”
“I strongly encourage anyone who has an event or group on Facebook that encourages law breaking to close the event or group immediately,” he said.
