More than 150 million pieces of rubbish
The CSIRO study estimates more than 150 million pieces of rubbish litter Australia's sand and shores.
The most common item was plastic following rapid growth in global plastic production.
"More than three-quarters of what we find in terms of rubbish is plastic,'' Dr Hardesty said.
This had a disastrous effect on some 600 marine species who then consumed what researchers have termed "plastic food".
Dr Hardesty said she had found cigarette lighters, toothbrushes, pill bottles and bottle caps in the stomachs of birds.
"We open turtles that have died and see that they're jammed full of plastics,'' she said.
"I've found over 200 pieces of plastic in a single bird."
