The only incorrect implementation of Australian-style Chicken Parmigiana is one where the chicken is not schnitzel. https://en.wikipedia.org/wiki/Schnitzel

Since every Pub and Restaurant serves some sort of Parmigiana (even the Vegan ones -Eggplant and Vegan Cheese) are acceptable substitutes), it is a good way to determine if the food is any good. Of course since Eggplant and Vegan Cheese always tastes terrible, Vegan Restaurants and Pubs are proof to this rule.

If you order a Parma at a dodgy pub and it is terrible, you can be happy that you didn’t order anything more complicated.

A whole, un-tenderised chicken breast, covered in a spattering of breadcrumbs, a slice of Devon, pizza sauce and some tasty cheese is not a Parmigiana, even though it is often served as one.

That said, the best tasting Parma I have ever had was at a local industrial estate café. It was a deep-fried schnitzel with a slice of sandwich leg-ham, left-over Bolognese (with the meaty bits and onion strained out) and shredded pizza-blend, on a bed of takeaway-shop chips and a salad consisting of fist-fulls of random vegetables from the salad bar.
