Indonesia's Customs agency has seized 210 tonnes of "toxic" garbage at the port in Surabaya and is preparing to ship eight containers of material back to Australia.
The containers were shipped to Indonesia from Brisbane on June 12, and were supposed to contain paper for recycling, but also contained mixed plastic waste and other contaminants.
The head of Customs at Tanjung Perak port, Basuki Suryanto, says his officials found electronic waste, remote controls, soft drink cans, cables, styrofoam and other materials in the containers.
