You are welcome.
Nursery rhyme? If there is one about a cat and a fiddle (fiddle is fiol in DK BTW. Just a bit of info for the nerds) I don't know it. Or it has been forgotten over time. I assume it's pretty old.
As to what M&F may come up with of activities for their children:
Well, Bella and Christian, who are older and by now must be at least reasonable proficient in English, will of course be easier to keep busy.
They could easily be brought along to see a performance of some sort. Perhaps a dance show, Bella might like that.
Christian may take part in sport of some sort. Soccer springs to mind. Or try one of the local sports, predominantly those that are popular in Tasmania.
As for the younger children. A trip to the zoo must be considered a must to experience the local wildlife I'd say. I'm sure Vincent will feel an urge to shout at some animals after a couple of days in Tasmania.
A bit akin to when the cows come on grass here in DK.
Have you got some kind of family friendly events going on here in December the family can look at? - While entertaining the photographers just like at the Hubertus Hunt.
Are there some kind of semi-official events going on in this month where M&F and family can be invited as guests. - Because then we may get a show like in Greenland.
Or is there a boat they could name or ribbon they could cut? Then we could have a show like on Samsø.
Apart from that I'm sure we'll see the family out and about in Hobart. Bella is soon reaching the "shopping-age".
And I can well imagine the oldest doing something on their own with their Australian cousins.
