Have a look at Wildearth's range - they are Qld based

eg Black Wolf has quite a lot of synthetic bags that may suit
Here's a -5 rated one with zipper venting for feet (comes in 0 deg too) at $149

My kids use various Black Wolf and Roman synthetic bags for scouting
-5 rating for winter
Fleece liner for when it's a bit colder, but this is bulky so not for a backpack trip (if base camping may use a swag as well)
It unfolds to be a camp blanket too

I agree with Wayno and I think for kayaking a synthetic bag is likey to be a prudent choice, as it'll retain warmth if it gets a bit damp, whereas a down bag will be useless if it gets wet..
