Without getting too much into the logical semantics of the argument, Australia does have disadvantage of having highly flammable things with leaves. That's why we gifted them to California a century+ ago ... so they could share the experience.
Looking down on a satellite image you can track the millenium movement of the original arrivals with their magic fire sticks in the far north west of the continent all the way through previously mega flora/fauna areas to the flame buffering mountains on the coastal fringes. A short visual trip across the sea to our neighbours left, right and above shows the effect of poor land management with green leafy uncontrollable stuff everywhere coast to coast.
Oz, unlike the UK, is one big island of metal, so it's a giant heatsoak that seems to have an affinity to fire due to elevated temperatures that close in on combustion flash points.
Then there's the ozone hole that had made its home above Oz and the Antarctic for centuries letting all that heat out like a giant chimney then DuPont decides to be a good corporate citizen and changes it's refrigerants and propellants, the next thing the atmosphere is heating up again....rapidly.
