Well Patchetts Pies look to be Sydney Based, I have scoured Woolworths and Coles and can't see any.
I did go to a shop 'Paddy's Butchers' on Cobham Road, Melbourne but got charged $88 for 3 pies, 3 cadbury's bars, 500g of sausage, some Bisto gravy and some Black Pudding.
The Pies weren't overly clever, but I doubt if I'll go back.
