Let me tell you a little bit about light and fire, the traditional way.

Well, firstly, our old people call our Gambia.

When we rub those fire sticks together, we're putting our energy into them.

And when that first spark appears, we give it life without breath.

And when you blow on the envy, you put your spirit into that fire.

And now you're a part of that fire.

So this place that we're walking into is sacred land to us.

You see by a monger, flying next to Gorgah, and they are part of our sacred mountains from the far south coast.

Tales from Australia of our changing relationship to nature and the environment.

We've come together to revive our traditional practice of cultural burning to heal the land after our country's most catastrophic bushfires.

Here at Crackland, all the insects will start lurving, everything will start here in that fire.

And we're bringing the rest of the community with us.

We've always known that the landscape was managed with fire because when the invaders arrived, they saw smoke everywhere.

This country has known fire for thousands and thousands of years, but not the kind of fires we're seeing today.

The last day of the decade has been 24 hours of bushfire and tragedy in Australia's southeast.

The entire communities have been absolutely traumatised and there could be worse to come.

Those fires? We're now calling them the Black Summer bushfires.

The bushfires season from hell. They burnt across the country for more than six months in 2019 and 2020.

Smoke and ash.

Up to 12,000 fires requiring 200,000 fire-fighting shifts, killing billions of native animals.
