Hey guys, I would like to give you a few details about shipping to Australia. First of all, it is very very easy. Customs let a lot of stuff through with no problem. In the last month, I have brought in about 20 knives from the states, including 8 from Busse and Scrapyard. I find that the best way to send is to get the person to pay extra for international express, it takes about 5 days. For normal airmail, it is much cheaper but the wait can be from 2 weeks to 6 weeks. Out of the dozens I have brought in over the 6 months, I am yet to lose in. Several have taken 6 weeks to arrive though.
Now for our rules, double edged are a no no. Especially anything looking like a dagger. Tomahawks with a spike, forget it. These things can be brought in with a special permit though and will be held by customs until the permit is approved. Also, no need to mark gift or reduce the value on the item because Australia brought in a new law that states the value can be less than $1000 AUD in a single package and not attract extra taxes or duties.
Oh and big point to note..only use USPS, whether express airmail or the cheaper and slower priority mail. Another good one is USPS international letter post for a small folder like an emerson. It is a hard cardboard envelope and costs about $5US to send to Australia. I no longer buy any knives at all from Australia, unless it is secondhand off a mate.
