Earlier this month, Liberal councillor Mitchell Griffin took to social media to speak out against the dumping of rubbish at the Metford site.

"This has become a site which is commonly visited by people dumping items, and undertaking anti-social behaviour," he said.

"As recent as Sunday (March 15), I witnessed four male teens damaging an abandoned vehicle which was left in the reserve.

"This has now been reported to the police.

"We have seen items discarded such as mattresses, cream gas cylinders, and wooden pallets.

"These items are discarded alongside and in the wetland, a wetland which flows in to Four Mile Creek.

"This is a creek that flows on through Tenambit, Chisholm and out to Morpeth.

"Since reporting this illegal dumping to council on Sunday afternoon, I understand that our local investigator from the Regional Illegal Dumping Squad is now investigating."

Council has operated a tip voucher system whereby each household is provided with a tip voucher every year, which allows them to dispose of up to 400 kilograms of waste at Mount Vincent Waste Management Centre.

However, only around half of the vouchers are used every year.

Late last year, councillors signed off on a 12-month bulky waste collection service trial with a report to be delivered on competition.

Cr Griffin said he hoped Maitland Council would find a solution to encouraging residents to correctly dispose of their rubbish.

"It is very tricky for the community, we have an externally run bulk kerbside pick up, but I am hearing from residents that it is very expensive," he said.

"A review of this service is due back by the end of the year and I look forward to seeing the recommendations from this.

"In the interim, people do need to be mindful of their waste.

"Our wetlands are used recreationally by the community, and is inhabited by kangaroos, birds, fish and other wildlife."

Council also runs a number of other free waste services including Mattress Musters, Drum Muster, Household Chemical CleanOut and free problem waste disposal at the Community Recycling Centre.
