The organiser of an electronic waste day expects the amount collected this year to pass 1000 tonnes.
The third 'e-Day' began at 9am on Saturday in 40 centres.
Some 2000 volunteers are collecting and recycle obsolete and broken computer equipment, mobile phones and digital cameras.
National organiser Laurence Zwimpfer says 950 tonnes of electronic waste was recycled last year and he expects the amount to grow this year as people become more aware of the value of e-waste.
He says computers and their monitors are full of valuable glass, copper and other metals that should be re-used.
