My suggestion is that if you can fit toys in with your other effects without huge expense then anything you can bring that will keep them entertained here is a good thing - and will save you time and effort trying to duplicate it all after you arrive. Actually your children probably won't want to spend much time on their bikes and skateboards during the hot summer months here, and depending on where you will be living, it might be difficult to find somewhere in your neighbourhood for them to ride around safely too.

By the way, while you're packing, I would be tucking a big jar of vegemite into a spare corner (if your kids like it) as it is very hard to find here and the few 150gm jars I have ever seen here cost a bomb! Hope this helps.
