Do those cities in Australia feel similar to Hong Kong?

Moreover, the pace of life in Australia is very slow, and the pace in Hong Kong is much faster than that in Australia.

Simply put, Hong Kong is like a city, and Australia is more like a village.

As for the temperature you mentioned, Australia has a vast territory, so the temperature difference between major cities is not small. Like Brisbane, it is very hot in summer, about 35-40, similar to Hangzhou. The lowest temperature in winter may be 2-8 degrees, but even so, you basically need a short sleeve and a coat during the day. But cities like Sydney and Melbourne can be relatively cold in winter.

Whether the electricity bill is expensive depends on the income of Australians, and some companies have discounts if they use it more. Personally, I feel that it is hot in summer in Australia. I feel the sun is strong and hot when I go out, and I don't feel so hot when I stay at home without turning on the air conditioner.
