" Here in Perth just over the hills there are millions of sheep grazing and yet I have to pay a fortune for lamb chops and I bought a small T bone steak the other day for $20 . "
Lamb chops don't come from sheep. Wool, lambs, and petfood are the only thing sheep provide. I used to enjoy mutton 30 years ago but it is not often available nowadays.
If you bought a T-bone steak from a sheep it must have been mighty small.

On a more serious note if the dudes in parliament think that breaking up Coles and Woolworths will give the public lower prices then they should rethink their 'thought bubbles'. I'm old enough to remember when there thousands of small grocery shops spread around on almost every street corner. They were always more expensive than the emerging 'supermarkets'. The rats loved them and 'Expiry Dates' were unheard of or ignored.

The larger the store the more likely you will be getting fresher products at a lower price. Milk I buy from Coles always has 7+ days to expiry but smaller stores? Not so reliable. "Woolies Metro" in a few central city locations are more expensive. That's the price people pay for convenience.
