BIG Brother is watching - your rubbish.

As part of a trial launched by the State Government yesterday, cameras in rubbish trucks will spy on the contents of household green waste bins in an attempt to prevent hazardous material from being put in the wrong bins.

Residents who put inappropriate items - which have previously included gas bottles, toilet cisterns, car seats and engine parts - into their green waste bins will be alerted via a two-step process.

Initially, stickers will be placed on the green bins advising them of what can and cannot be added.

If the camera continues to detect banned items from an individual bin, a bright orange sticker will be placed on the bin, informing the householder of what they are doing wrong.

Almost 10,000 homes will participate in the three-month trial.
