Welcome home (mate). The most common language spoken in Australia is English, but I would not suggest trying an Australian accent unless you have practiced it a lot. (The "mate" is optional and is part of a stereotypical Australian accent. It would sound like "'Welcome 'ome, mate!" if you want to stay stereotypical.)
