There is one in our local deli that claims 3% Australian. Truly disgraceful issue, but apparently "we " will not pay for Australian grown and processed.
Currently buy Bertochi 400 gram prepack, which is 98% Aussie and gives us 4 serves. Also has a good shelf life.
One of our local butchers Desmonds Meat Service, Taylor street Kadina smoke their own bacon and hams from locally sourced pork, excellent quality, well worth a visit if passing through.
Same argument as any imports though. Why do we need a $1.50 tee shirt from Bangladesh? sold in K Mart, Big W, etc. We really do not, just another importer getting rich on the back of some sort of misery. Try to read the usually misleading labels and buy Aussie. We now have a bit less bacon so that we can afford Home Grown.
Take note that Ham is also mostly the same imported stuff.
Many years ago I was told by a butcher's company that the only way to guarantee the meat was Australian grown was to see the bone in it. A lot of our pork comes from Canada and apparently our quarantine rules prohibit the import of meats with a bone in.
I also stay clear of frozen vegetables where the packed says packed in New Zealand. Some time ago a TV show did a story on foods from SE Asia being repackaged in NZ and then shipped to Australia.
