No temperature extremes? With regular forays into the 30s in the warmer months and temperatures in the 40s not being unheard of, I would contest that. This is even more the case in the north of the state. We also have colder winters than most of the rest of mainland Australia (although nothing like many places in North America, Europe, Antarctica, Patagonia, etc or with very high altitudes) Victoria is also very car dependent, meaning more people are less prepared for being outside building/vehicles than in a more public transport/walking/cycling place.
