You are correct, no doubt. The consumer does make the market.
I do try and buy Australian made things. I shop at the local small green grocer and the local butchers, but not always just most of the time.
I actually drive a falcon. Nice car on the highway. I even bought an Australian Guitar which is a Cole Clark, great instrument.
As for clothes it is very hard to buy Australian made, but I own a suit that was made from Australian Merino wool shipped to Italy and made into a suit and then shipped back to Australia and sold to me, nice suit, but go figure why we couldn't have made it in Australia because it is not a cheap suit.
