Fellas what distinguishes an Aussie donk from the Chinese gear?

I have seen some Aussie made jobs are stamped or have the logo on a sticker. Some of those square "crate" types that look like the bottom of a milk crate, engine tops are identical to there Aussie made jobs but don't say so.

What's an easy way to tell when you are looking at pictures on the Trading Post, Ebay etc?
