In a few days I'll be hitchhiking across Australia from Perth to Melbourne (and then up to Sydney).
Now I've heard it can get surprisingly cold in the outback at night. But I don't know if that's just in the centre or just in the cold season.
Most people I would imagine would include the Nullarbor Plain as being in the Outback. But it's also on the coast.
I know it's already hot in the cities in Australia so I'm expecting this route to be be 40C+ during the day, but should I expect warm or cold nights?
