In the first video of a new series, we visit the High Country. Travelling out to the far NSW side, our first goal is to climb Mt. Kosciuszko, detailing all the different ways it can be done, some easier than others. And at the same time, explore exactly how this was named after a key figure in Polish history with seemingly no relation to Australia.

And although this is the highest point on the Australian mainland, it's far from the highest in Australian territory. We explore how the other high points compare - but they are a lot harder to get to.
