Mateship means being a good friend. It's like having a really close friend that you can depend on no matter what happens. You know that they will be there for you when you need them, and you will be there for them too. It's not just about having fun with your friends, but also being supportive and helping each other through tough times. It's about being loyal and respectful to one another. Mateship is very important in Australia, and it's a big part of what makes Australian culture unique.
