Lol @ mate.

I'm always cautious when writing other people languages. I did it a few times with eveuncovered in Finland a few times and I buggered it up. She sets me straight though.

I googled australian slang and mate sounded good😂🙈

Mate works...I use it a lot. It's usually used for males, not so much female's but can be. I use cobber a lot too. It means companion, friend. Again, most commonly for males.
