Take your dogs and leave early. The Cats and birds will work it out...
If you live in the hills, surrounded by scrub or Forrest, why would you stay? I'd leave early, and not take the chance. Fires travel too quickly, roads get congested or closed, it can become dark during the daytime, and people panic when they make the decision too late.
Our forecast is 44 degrees with winds up to 40km/hr tomorrow. Luckily we live in town, it's flat, and we are surrounded by an irrigation district, so the chances of a bushfire here are very remote.
All the best.
