Have you ever tried to seriously get around in the wet season?

40 - 50 degrees, 80 - 100% humidity, Flood plains wet and boggy so vehicle access difficult, easily cut off if it rains hard and floods the creeks so a 2 - 3 day wait for the creeks to drop.

I'll walk kms in 35 - 40 degrees but above that it starts to take it's toll.

That's just my experience.
