nah, it's a thing in new zealand, the maaori like to tatto their face to look more scary... australians don't do this, they are more stealth killa because the land is so dry not many people to run into on an average walk in any direction, so their favourite weapons are spear, spear with woomera (a lever to launch speers harder), heat and resin hardened clubs (modern colloquial they are "yulbe" or "you'll be fucked if it hits you" and of course boomerang, but that's for killing birds and small animals
