Anneka Rice says the Challenge Anneka reboot is all about communities coming together to help worthy causes, but usually 'all hell breaks loose'.

ANNEKA RICE: It's all about community. I mean, that piece we've just seen sort of sums it up, doesn't it? It's all about communities coming together.

And with Challenge, what happens, we take on a cause for a charity usually that is just too big, costly, complicated, impossible for them to achieve on their own. It would take months. They would never be able to afford it. And we do a lot of pre-planning and we scope it out, and we work out how we're going to do it.

And then we literally throw down the gauntlet and say, all those people who've pledged to help, what if we had this window? Let's try and make it happen. And then all hell breaks loose. And we try and do this huge project, which might take literally months, and we try and get it done in just a few days.

- Yeah, it's incredible.
