I know this is a very specific question, but it's difficult to figure out!
I've heard the beef here is often grain-finished (depending on rainfall and the seasons), and this is a selling-point for many suppliers.
But what about lamb/goats? On the whole, is it likely they would be grassfed? I'm talking Woolworths/Coles/local butcher meat.
They're not short on space. I can't say anything definitively, and it almost certainly depends in general on circumstance and season perhaps, but as a rule I don't think any country corrupts its livestock in quite the same way as the US so there's not much to worry about.
Lamb doesn't respond well to intensive farming so is one of the meats that's messed about with least. I'd have thought there's a stronger chance of it being grass fed and approaching organic than any other standard meat.
I'd echo what others have said that most lamb is left on pasture year round. I love this time of year in the UK with all the spring lambs in the fields!
A lot of lamb/sheep (and goats) graze on land that's unsuitable for agriculture or for cattle, so they're left to it.
Woolworths & Coles - will be grain finished.
Local butcher - ask. They are all going to be different. Any good butcher will be able to tell you. Go to the Sydney markets and ask, I can guarantee that you will find 100% grass fed no worries at all. If you were in Adelaide I could help you out.
PS - Suz - Paleo Oz - will be able to help you out, she is in Sydeny.
UPDATE - Sorry, I mis-read the question - Australian lamb is not usually grass fed at all (sorry, I just quickly read the question and thought you said beef). My answer stands for beef, but lamb you should be fine, even with Woolies and coles. My bad :)
