"It's really important for people to report wallaby sightings to us as soon as possible," said council biosecurity manager Greg Corbett. "Our chance of dealing with these animals is much greater if we can get a dog on site before the scent trail goes cold."
Wallabies are listed as a containment pest in the Bay of Plenty Regional Pest Management Plan and are unwanted organisms in the Biosecurity Act, which means it is an offence to move or release them.
They cause significant damage to native bush by feeding on native seedlings, ferns and grasses.
They can also cause problems for forestry and farming by feeding on pine and eucalyptus seedlings and competing with stock for pasture.
Once established in native bush, wallabies feed on seedlings, altering the species composition and ultimately depriving native birds and animals of food and shelter.
The council is also concerned hunters may be shooting female wallabies and taking the joeys home as pets.
"This is an offence," Mr Corbett said.
"People keeping wallabies as pets may also contribute to their spread as the animals have a nervous temperament and a strong drive to escape from captivity."
Wallabies are grey/brown in colour, with adult animals having a paler grey underbelly. Females weigh up to 5.5kg and males up to 7kg.
Sightings can be reported by calling 0800 780 773.
