We have consciously been focusing on buying more Australian food products, except for rice which I don't believe should be grown in Australia. OK, maybe tropical Darwin environs might be ok, but they tried and the magpie geese ate all the rice.
R uses cans of tomatoes often enough when cooking. We were buying cheapish ones and upon reading the label, we realised that they were imported from Italy. We are now buying Australian canned tomatoes and pay maybe 70 cents more. I can't understand the economics of growing tomatoes in Italy, canning them and sending them by ship to Australia and they are seventy cents cheaper on our shelves than ones we grow and can ourselves.
I make an exception for NZ and buy their cheaper powered skim milk. They are almost us. I am Closer Economic Relating. Even so, the cheaper price still doesn't make much sense.
We try to only buy Australian oils for cooking with. Malaysian oil is cheaper, but are we are buying Australian oil. We use peanut oil, olive oil and canola oil and a little sesame oil. You can't get Aussie sesame oil.
Olive oil is an interesting one. A huge amount of imported olive oil is muck and not virgin as it is labelled. There are efforts to clean the industry up, with a certification scheme possibly operating by now, but we will only buy Australian olive oil now. Australia is the ideal country to grow olives.
The argument over no brand name against brand name was lost for us a couple of decades ago when one of those tabloid current affair shows counted the number of baked beans in a brand name tin, as against a no name tin. There were many beans less in the no name. Every so often we give something a try, and it is not as good and often imported. I was buying no brand name sugar, still Australian though, until one lot had black bits in it and we have reverted to CSR sugar.
We have only bought free range eggs for a long time now. We now only buy free range pork and we are looking to only buy free range chicken soon.
I do get importing luxury food items. Aussie caviar is never going to take the world by storm, let alone us, but why do we need to import basic foodstuffs that grow well here in Australia? You whistle and I will point to Woolworths, Coles and latterly Aldi and Costco.
