Yes, perhaps next year?
We have seen Bella and Christian acting like pros in front of a lot of people quite anumber of times now.
And last summer we saw Vincent and Josephine comfortably facing very enthusiastic crowds of up to several hundreds who looked different from themselves and in strange surroundings. And next year they'll no doubt have a rudimentary grasp of English for them to understand that all those strange people just want to say hello and are glad to see them.
So I think it will be a fairly safe bet to say the family will go to Australia next year. - I just hope that at least M&F this time will drop by New Zealand as well.
It's difficult to make predictions, especially about the future...
