Oh Nuddle, another German on here!!! How long have you been in Australia and where do you live?
I personally didn't want a timber one. I have one I got from ebay made by JDBug. It's the one that looks like a Motorbike. I thought it looked cool and as mentioned earlier you can add pedals later once they can balance.
If you prefer timber, there are ones that have a "handle'' which I think is quite handy for the time that your little one doesn''t want to ride anymore and you have to carry the thing. With metal one, you can just carry by the frame (and they're usually lighter) but the timber ones are a little more awkward to carry. Also have a look at the larger bike shops is your area. They might carry them (I rang around to save me from running around) so you can have a look and even let your kiddo sit on one.
