Nice thought, but I'm OK with paying what's due. I will try to find the best option though.
I've been looking at eBay recently, trying to buy some musical intruments, and have seen a similar (probably slightly larger) sized parcel, for which the auction quotes £40 for postage to Australia. I think that would be a really decent price. I've sent the seller a message, asking what his shipping method is, and explained the situation. I'll also bid on his auction if the price remains reasonable.
Unfortunately, the market for these toys is quite limited in Australia, and the prices tend to stay very high, often higher than retail for the more desirable gear. It could be worse though.
