I'm afraid not Katie,
It's traditionally obtained from a supper type trailer, a caravan (a famous Harrys Meals de Wheels or something like that I think it isin Sydney, though Harrys near the Finger Wharf I also think is pretty well anchored these days)that someone sets up to feed the night club and late pub leaving staggerers or the local greasy spoon Cafe and what it looks and tastes like at stage probably does not matter too much - but probably better than raw chicken I feasted on one night out of a refrigerator when in a similar state of decay.
Pies are probably the el cheapiest ones you can get and a load of peas can have that mush appeal after a few - best to mix it all in.
You can get some super Pies by themselves from boutique Bakeries and even specoalist Pie shops, Beef and Burgundy, Cheese and Bacon, Curried Chicken and even a curried prawn one I found a few days ago.
here you go
www.harryscafedewheels.com.au and there's now four locations but Wooloomooloo is the original and rightly so a national treasure -

And I'm not too sure whether Harrys does the pie floater as think it was originally an Adelaide delicacy
