The three new drivers of the Australian economy

*  craft beer
*  burger joints (other than the fast food chains)
*  salmon (farming and eating)

As it happens, I pretty much approve of all three (with a reservation about the number of burger joints).  

PS:  my daughter observed last weekend that she could live purely on salmon (pan fried with crispy skin), mashed potato, and garlic beans.   I then cooked that for dinner.   [My wife is a fantastic cook, but I do make the best mashed potato.]
