This annoys me.
I think this confusion started when Trevor Goddard played the role of Kano in the Mortal Kombat movie.
Which he played with a British accent anyway. Since the guy had a fake Australian accent. The thing about Trevor Goddard is he always claimed to be from Perth Western Australia to further his career, it was found after his unfortunate death that he was actually from the UK. His IMBD profile says this.
"While Goddard's official biography listed his place of birth as Perth, Australia, and the year as either 1966 or 1965, his parents, Eric and Clara Goddard, of Bexhill-on-Sea, East Sussex, in July of 2003 came forward to state that Trevor was in fact born in Sussex, England, his date of birth was in 1962, and that Trevor's claims to being a reformed criminal from Australia were in a fact a fabrication. He was able to fool many into believing his London accent was an Australian one, and edged out many authentic Australian actors for roles.
His portrayal of the 'Kano' character in the Mortal Kombat movie directly influenced the evolution of the character in later Mortal Kombat video games. For example, in Mortal Kombat: Deadly Alliance, Mortal Kombat: Deception and most recently in Mortal Kombat: Armageddon, the character of Kano had a characteristically Australian accent and personality, as exemplified in the Mortal Kombat 1995 film."Personally this guy always shit me, because his accent sounded like an American pretending to be an Australian.
As far as i'm concerned Kano is british, he never at any point sounded Australian in the first place.
