There is a very good online retailer in Gore...

G5 $1320 (incl gst)
5700 $1749 (incl gst)
These are NZ models. I got my A40 from them last year.
There is another online retailer
http://www.etown.co.nz/
G5 $1145 + gst ($1288 incl)
5700 1421 + gst ($1598 incl)
These are 'grey market' models imported from Asia... still exactly the same models as NZ but without a local warrenty. I got an A70 for my father from there.
There is quite a good thread on the Australian forums on digitals for weather photography

Agree with NZStorm re the polarising filers - I'm a big polarisor fan, both of my SLRs have polarisors in their camera bags ready to go. Although I can put one on my A40, I find I can compensate by using a little manual under-exposure...
Also think about batteries - many digital camera use rechargable lithium-ion packs which are expensive to buy ($80-$140+) if you want to have a spare pack. One of the main selling points of the A40 and A70 for me was the AA battery size which means I can get a couple of sets of rechargable 2000 mAh NiMH batteries without damaging my Visa.
Add on another $100 for some memory for the camera. 128mb CF cards can be picked up for around $80. Many cameras come with small capacity cards (eg 8 or 16 meg). Also check out the price for the media that the camera takes... the likes of compact flash (CF) cards are cheap, SD is more expensive, and Sony memory sticks must contain lots of gold and titanium and other assorted rare metals.
Cheers,
