ABC reports that John Rau said Queensland has increased the limit for housing free-range birds from 1,500 a hectare to about 10,000 birds.

While there is no jurisdiction to stop the eggs entering South Australia, he said he hopes shoppers will support South Australian producers who are working towards a limit of 1,500 hens per hectare.

"What we're talking about here though is to develop our own South Australian label for free-range according to our criteria, which we would hope consumers would recognise and make their buying choices around looking for products with that South Australia free-range label on it."

The South Australian Government hopes to finalise labelling laws for free range eggs in the coming weeks.
