> Australia’s unusually harsh sunshine results mainly from its location in the Southern Hemisphere. The elliptical orbit of the Earth places the Southern Hemisphere closer to the sun during its summer months than the Northern Hemisphere during its summer. This means that the summer sun in Australia is 7 to 10 percent stronger than similar latitudes in the Northern Hemisphere. Air currents high in the atmosphere sometimes bring ozone-depleted air from Antarctica’s ozone hole to Australia, letting even more UV through. And Australia’s sunny weather and relatively pollution-free air provide little additional protection from harmful UV rays.
Thanks, I learned something today! Does this apply to other countries such as Chile, Argentina and South Africa?
Stronger != Closer

Thanks, we know already.
> Earth’s closest approach to the sun, called perihelion, comes in early January and is about 91 million miles (146 million km), just shy of 1 AU. The farthest from the sun Earth gets is called aphelion. It comes in early July and is about 94.5 million miles (152 million km), just over 1 AU.

So It’s more that Australia is pointing at the sun while the entire earth is closer, and also, the rest of Southern Hemisphere too
