Offenders could face fines of up to $110,000 for dumping household waste in Meroo National Park near Burrill Lake.

Danielle Mckenzie was walking through bushland in the park over the weekend when she stumbled across the pile of waste on a four-wheel-drive track.

The rubbish included household items, such as a plastic table, toys, bed frames, doors, buckets, figurines and a Australian flag.

Danielle said also among the junk were framed paintings, photographs, pieces of wood, a timber cabinet and a fishing tackle box.

She said an area nearby had been cordoned off with warnings about asbestos that had been dumped.

“We stumbled across it while walking from the aboriginal caves to Wheelbarrow Road,” she said.

Meroo National Park ranger Meghan Kempster told the Times individuals can face on the spot fines of up to $4,000 and, if the case goes to court, illegal dumpers can face fines of up to $110,000 and more for businesses under the Protection of Environment Operations Act.

She said the Meroo rubbish was household waste and the case was under investigation.

Anyone who finds rubbish in the bush should contact relevant authorities, such as Shoalhaven City Council, NPWS, or Police, immediately so it can be dealt with an an investigation launched.

Ms Kemspter said illegal dumping was usually a way for people to avoid paying tip fees, but she said the fines far outweighed the cost of tipping waste.

She said dumping was unsightly, could attract vermin and often spread weeds into national parks.

“It also often leads to the closure of roads in hot spot areas,” she said.
