MATT HART: Each number does have that equal chance of being drawn. But I'm always amazed when you see that sequential numbers, when you see, you know, a 31, a 32, 33, 34, because if I'm marking a coupon, I would never pick those numbers, thinking, gosh, what are the chances that you're going to get those sequential numbers. But they do happen.

And I think that's why I generally go for a quick pick, because I have that bias that I would never mark sequential numbers, but we often do see sequential numbers. And that sort of batch of numbers is just one of the many combination of numbers that are possible. So I haven't been around when a 1, 2, 3, 4, 5, and 6 have come out. But it is one of the potential options.

I think the only funny thing there is that if 1, 2, 3, 4, and 5, and 6 do come out in say a lotto draw, I think there'll be heaps of Division 1 winners, because I think a lot of people have jokingly marked their coupon with a game that has those numbers. The other really interesting thing, if all of the numbers drawn are 31 and under, we generally, as a rule of thumb, will have more Division I winners, because people often mark their coupons with family birthdays.

Sometimes really the margin between the most frequently drawn and the least frequently drawn is not that much. And it can change quite a lot after just one or two draws. You know, what's the most frequently drawn number and what's the least frequently drawn number. The interesting thing about the lottery balls, I think, is that they are highly regulated. They are like our crown jewels. They are under lock and key.

They sit in this room where a government official and one of our team have separate keys to open it. And both have to be there to open the door. They can only be touched with gloved hands. They're regularly washed. And twice a year they go to the National Measurement Institute and are weighed.

And so that is a lab, and someone in a white coat will sit there and they will weigh methodically each lottery ball to make sure they all weigh the same, that no number has a greater chance of being drawn from the machine. So it is quite a process. It's quite bizarre to watch them weighing lottery balls. It takes quite a long time. And they take it very seriously, of course.

But it's sort of one of those really unusual behind-the-scene things, with lottery draws. So it is quite a process. And they're quite expensive balls. So they're not, we didn't just pop down to Rebel Sport and grab some ping pong balls.

These are, they come from a specialized manufacturer overseas. They have a little chip in them, so that when they come out of the machine they can be read by the machine. And they're quite specialized pieces of equipment. They may not look at times, as they're spinning around there.

And I've been to the draws sometimes just to watch them being drawn. And only people with a license can touch these lottery balls, to load them in the machine, to unload the machine. It's not just anyone can do that, only people who've got a special license can do that. And they go through background checks and all sorts of things, just to make sure that integrity of the draw is maintained.
