Run a Google search and you will find some but I think you have to buy large numbers of kits to do any good. I googled it once and the minimum was around 500 I think. Then you have to check Australian Customs to see if you need a licence to import large quantities into the country - maybe that no longer exists.
Also check with the Australian consulate or embassy in China as they will have a list of businesses registered. Unless you are setting up a retail business or planning on mass producing pens I wonder if it is worth the effort.
Best of luck
