Australian households are being urged to take extra care when disposing of waste after authorities detected a hazardous biosecurity breach.

Officials say contaminated material was found in a household bin, raising concerns about the spread of pests and diseases.

The incident has prompted renewed warnings for residents to separate and dispose of biosecurity-risk items correctly.

Authorities are reminding travellers and the public not to discard restricted food, plant, or animal products in regular household rubbish.

Improper disposal could threaten Australia’s agriculture, environment, and food security if dangerous pests or diseases are introduced.

Residents are encouraged to report suspicious items and follow biosecurity disposal guidelines to help protect the country.
