Day Walks around Sydney in the extreme hot weather

Residents of the Greater Sydney Region, visitors and guests past and present, what are your favourite walks to deal with these outrageously hot conditions and still enjoy being out in the bush?
I usually head for the Blue Mountains or somewhere along the coast. We spent last Saturday afternoon scrambling up a very steep track beside several waterfalls and cascades in rainforest at Macquarie Pass near the Southern Highlands. It was very pretty to look at but uncomfortably warm, even in deep shade.
I have to get into the bush for at least half a day every weekend or I go stir crazy. Right now we have unrelenting extreme temperatures and zero rain (as with many other places). Don't usually have any trouble planning walks, but currently I'm stretching the limits of my imagination and experience to come up with day trips where I can stay relatively cool. With predicted temperatures for Western Sydney this Saturday and Sunday around 42 degrees it's starting to look like Mission Imposssible

Actually some Tasmanian snow would be really good about now
