Saw the other baby carrier postings lately and did some searching and found this one. It can be used to carry a baby in 3 positions - front/hip/back - up to about 20kg, so it's quite versatile and it's also 100% cotton.
It gets good reviews on both Amazon and ProductReview.com.au (http://www.productreview.com.au/p/ergobaby-organic.html). Local retailers seems to price these at about $180 from a quick Google search.
You have to click on the "Amazon.com" option in the "More Buying Choices" panel on the right hand side to get it delivered to Australia. The green one is the cheapest at $84.06 USD, brown one and blue one are about $10 and $15 more expensive respectively. Shipping was around $11 USD to Sydney for me, there was an automatic discount of about $5 when I checked out.
If you don't mind, my referral link is below :)

Can you still use this on non-organic babies ?
