Welcome to the Sweden board, Sammy!
Well, there are always a lot of Swedish supporters in Australia, most of them are always living there, but I think a few only come for the tournament.
So this is the reason why the Swedes get great support every year. So far I could unfortunately only follow the Australian Open on television (I live in Germany), but there have been many Swedish fans every year.
So I am sure it will be the same this year and of course, they will also cheer for Robin!!! It would be strange if it won´t be like that...
I hope this answer could help you
Have a great time!
