some where in preston

Preston is in melbourne

There's also a Preston in the UK and vocab is similar, although the male police officer's hat shows that it's not UK

Its not like I'm a dialect expert, and as someone else mentioned the vocabulary sounds very similar to that used in the UK, my first thought being Scotland. Also, I wouldn't know the distinction between the hats of police officers in different countries. That's why I put "wherever" as a broad cover. The point was that the cops didn't arrest him, not the exact location.

As an aussie, that's certainly aussie ;P
