Also I wanna address this but like. To literally anyone. Uh.
Don't do this. And lemme explain why.
Shortly--there's no telling.
Aboriginal Australians don't live in "tribes"--that's a term with racist connotations. They call themselves mobs, or nations for larger interconnected skingroups, and are typically divided into different clans, or familial groups. That's neither here nor there as it's only partial to her question.
The biggest thing is that Fantasynamegenerator usually doesn't take the actual names used by racial groups, especially Indigenous groups, but rather uses the naming conventions to create new names that sound like they could be from that group. This means that Bilay is likely not an actual name specific to any Aboriginal mob, and even if it is, tracking down which one(s) it would be from is nearly impossible.
Names are treated as something sacred amongst Indigenous Australian cultures, and I highly recommend not adopting any Aboriginal Australian name or even creating a character from any Indigenous group unless you do your due diligence to properly represent that group and ensure that your portrayal is free from racism or misinformation. Most mobs of Australia do not allow free teaching of their languages because they're considered "closed languages"--Aboriginal Australian cultures, by and far, depend on oral tradition as none of them have their own alphabet or writing system. Their power is in their words, and so their languages are very closely guarded and are not shared freely. This applies especially to names, which are considered sacred because they hold power over the individual.
If you insist on making an Aboriginal character, you should pick an English name. Most Aboriginal Australians have an English "whitefella" name they go by when introducing themselves to non-Aboriginal people. Aboriginal names are not shared freely, and for most mobs an individual will have up to six names they go by depending on mob, how they're being addressed, who is addressing them, and the context of their addressment, such as whether or not they're even present or if they're being referred to while absent. There is no singular name an Aboriginal person will go by except their English name, and this is used when interacting with white people only. Anything further, unless you have someone who is Aboriginal that you can personally consult, is cultural appropriation.
That's all. Kthxbye
