their names and addresses were spotted in the trash.

Their personal details were discovered by eagle-eyed park rangers who tracked them down.

And now they have received written warnings from Government.

But future offenders will not be so lucky -- they face being fined up to $1,000.

Dumping of such waste at beaches, bus stops and other public places is also illegal, and similar fines will be meted out.

The warning came yesterday from the Department of Agriculture and Fisheries.

A spokesman said workers have been forced to work overtime on weekends emptying trash drums at beaches and parks.

People had been dumping sacks of household garbage in the drums, causing a massive build-up of waste.

He stressed the drums were meant only for park and beach users.

"A few red-faced offenders have already received written warnings after their names and addresses were spotted in some of the garbage and they were tracked down by park rangers.

"If the problem persists, other persons who are tracked down will be prosecuted.'' The spokesman said all public parks and beaches were being used as dump sites.
