The price on AAA eneloops has just dropped, according to CamelCamelCamel:
http://camelcamelcamel.com/Sanyo-eneloop-Pre-Charged-Recharg…
Note this is actually for packs of eight AAA Eneloops, but when shipping is added, the per-battery price doesn't get good until you buy at least sixteen batteries, hence the title.
Price for eight batteries is US$16.35 + US$8.48 delivery = US$24.83 = about AUD$23.93 according to Google
Price for sixteen batteries is US$32.70 + US$10.97 delivery = US$43.67 = about AUD$42.09 = AUD$2.63 per battery.
Note these prices assume you use a 28 degrees credit card, otherwise you will probably be paying a surcharge for the currency conversion.
The link to the right is a direct link to the Amazon page for this deal, but please use the CamelCamelCamel link above, and spread a little bit of the joy their way for offering such a nice (and free) service. (No, I'm not affiliated with them).
And finally, yes, you can probably get these batteries a little cheaper off an Ebay seller. This deal is for people who want to be sure they are getting genuine Eneloops, and not worry about the possibility of getting fake ones.
Edit 7PM 1/9/12:
There is now a newer deal for AAA Eneloop batteries, and it is slightly cheaper if you only want four or eight batteries:

These are glitter Eneloops, too.
Price for eight is $22.83 delivered, from ShoppingSquare, which is about $1.10 cheaper than this deal. You can also buy four for $11.90 delivered. However, this Amazon deal is still cheaper if you want 16 or more batteries, or if you have something else you want from Amazon and combine the shipping.
Lots of votes, which is good, but no comments?
I was hanging around to answer questions, but as there are none, I'm off to bed.
