In Australia, genetically modified products are heavily regulated and controlled under the Commonwealth's Gene Technology Act 2000 and subsequent legislation, by the Office of the Gene Technology Regulator.
In Choice's 2016 article "Are you eating genetically modified food?", it notes that:
"There are only two commercial GM broad-acre crops grown in Australia – GM cotton and GM canola. These are both found in many margarines and frying oils."
"There are no GM animals or fish being grown or raised for food in Australia; however, meat, dairy and eggs from animals fed imported GM feedstock are available to consumers in Australia."
As of August 2018, this information is confirmed by the Agriculture and Food Division of the Western Australian Department of Primary Industries and Regional Development.
Before a genetically modified food can be sold in Australia and New Zealand, it must be approved as safe to eat by Food Standards Australia and New Zealand (FSANZ), who provide a list of approved genetically modified foods.
And once approved, these foods must be labelled per the Food Standards Code.
