May 8 is a date that many Australian's refer to informally as "Mates Day". It has even been suggested as a better date to celebrate the greatness of Australia, in preference to the current Australia Day that does not have the same meaning to all Australians.
May 8 is a great opportunity to focus on friendship and being a good mate.
The Mates Day badge design features two interlocking sparkly rings, one is silver and the other gold - just like the song:
Make new friends, but keep the old
One is silver and the other gold.
A circle's round, it has no end
That's how long I want to be your friend.
