My name is Heather Lateral, and I'm the coordinator or founder of "reverse advent calendar" in Australia.

You start with an empty box, and instead of taking something out every day, you put something in, so food or toiletries and Christmas treats for 20 days.

And at that point, the box is usually pretty full, and the box is then donated to a food related agency, where it can then be given to a family in need.

I was really seeing the power of it and the impact on my family, but really just planted this seed in me that there was something bigger in this, and I really wanted to see more people do it.

So I put on Facebook. Would any of my friends like to join me?

And I thought maybe I would find four friends that would join us that year, but the response was incredible.

We ended up with over 70 boxes.

I loved it, like it was amazing and I just loved seeing how much other people got from it and then seeing the combined boxes come together to know what a difference it would make.

Which blows my mind to think that from one box in my family, in just four years, it's become 4000 families or individuals across Australia.

They will have more food in their tummies and also that feeling of that they've been cared for.

We hear stories like moms who because of that food, they're able to free up a bit of their own money to purchase their children a Christmas present.

One asylum seeker family where the dad was able to choose not to work on Christmas Day because they could afford, because of a box, be able to be with his children on Christmas Day.

People often say, it's such a busy time at Christmas, you know, how are you managing?

But I find it energizes me. It just gives me so much joy and excitement.

But I would love to get to a point where anybody in Australia who wants to get involved and feel the reverse at that kind of box would be able to access one and do it.
