My native language is Australian. So the proper way to greet someone in Australian is, "G'day mate, how's it goin?" Translated: "Good day friend, how are you?"

With proper I think you mean formal, right? Formal way in Dutch: "Goedemorgen/goedemiddag/goedenavond, prettig/aangenaam kennis met U te maken. Mijn naam is ...insert name..." Goedemorgen = Good morning Goedemiddag = Good afternoon Goedenavond = Good evening Prettig(aangenaam) kennis met U te maken = Nice(it's a pleasure) to meet you Mijn naam is .... = My name is ....
