I have a couple of jackets that I use depending on weather and what I'm doing - they vary from down jackets (I have 2 of those, one thick one, one thinner one), to full waterproof goretex type.
For what you're looking for, I'd be looking at what's available from
Mountain Designs,
Kathmandu and the ilk.
If you're not wanting waterproofing, there's not really much need to look at softshells, as they are semi-waterproof (waterproof for long enough to put another jacket on over the top type waterproof)
It almost sounds like you're looking for a full zip fleece jacket rather than a soft shell, and in that case just look for one that is Polartec - I swear by them, with the oldest one I've got now approaching 20 years old!
Personally, it's just gone cold enough here that I've got my Mardale out, which is very similar to the Buffalo jackets like this
one... might be overkill in Northern QLD, but ideal here on the NSW Northern Tablelands... I've been swimming (kayaking) in November in the Thames before wearing one of these, and still be warm after getting out the water, and because I was warm, it started to dry itself out...
