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.)
You can say "Dobrodošli kući" in Bosnian, which translates to "Welcome home."
welcome home
Usually a simple G'day will do it.
The only Australian word for 'welcome' is welcome.
You could say "welcome back" or "glad to see you home."
welcome back
you say Akwaaba( which means welcome). Ghanaians normally say welcome in general. so when you want to welcome someone home, just say "Akwaaba" pronounce (A-kwa-a-ba).
