I really have no suggestions because I live in a warm southern state in the US so even in winter I hardly ever have to worry about getting TOO cold. I would LOVE to be in Austrailia in the winter (or anytime for that matter). I've always wanted to visit that country.

I personally enjoy cold weather, it just bites because it's dark at 5:00 p.m. in the winter and I have to ride on the trainer instead of outdoors.

Right now it's just hot, so I have to go early or in late evening to not have a heat stroke. It's just always too stinking hot in the south..but the food is great!
