Congrats. I know how exciting and agonizing it is waiting for your bengal kitten to come of age. I think your kids will love having a bengal too.
An outdoor enclosure is usually a pretty nice, deluxe thing you can do for your cat. But I don't know what the wildlife situation is where you live or how safe that would be. You'd have to judge that.
For toys, I recommend this place:

I think the best thing you could get for your kitten though is a really big, and more importantly tall, cat tree. Buy the biggest, sturdiest one you can accommodate, and put it in a room where your family spends the most time. Your kitten will love it. I think I currently have 4 such trees
There are quite a few Australians here on the forum, hopefully some of them can recommend some food that is locally available. Barring that there are a lot of good discussions about that in the nutrition section of the forum.
