Now that is kind of funny!! Selling them cheaper on Ebay then on the website, lol, nice catch!!
As for selling Bellows/shipping to Australia, sorry, but I would not even know how to do that.
Never shipped anywhere but USA and Canada.
I can second the macro rail mentioned above! But, if you check Ebay you can typically pick up a nice Spiratone (older but excellent) 2-way rail for ~$50US or so. Macro rails are a must IMHO for macro photography, they really make focusing soooo much easier and faster too!
