I've got a pretty reasonable handle on the towns and rivers and other geographic features of the bits of the east coast of Australia that I've travelled around. If someone mentions a town, I've probably got at least a vague idea of where it is. This is almost exclusively because as I've driven around, I've seen signs that tell me which town I'm driving through, or could turn left to reach, which river I'm crossing, and which mountains are around abouts. It's knowledge by osmosis.
On the other hand, I can tell you two fifths of bugger all about the lands of the peoples who were here before the Poms decided to send their criminals over here. I decided that this was a distinct gap in my knowledge, and went looking for instructive materials. One of the first things I found was this map. I haven't shown it here, because I think that might be breaching copyright, but you can look at it at that site (or download the pdf here for detail). The first thing that will hit you is that it's a mug's game to try to memorise who lived where, or even all the names of the nations - just like no-one thinks anyone is going to memorise all the towns and rivers in the country.
So want I want to see is signs on major highways and arterial roads, the same places that have signs for towns and other landmarks, letting me know which traditional territory I'm in now. So that same osmosis can work for me. So that we can all become familiar with the local peoples.
You may be wondering why I care about what may seem to be just historical lines on a map. It's because it isn't about where people lived, it's about who people are. When we refer to those people who were here before, we use white man's words to describe them - Indigenous, Aboriginal, Torres Strait Islanders. We do it because we don't actually know who they are. Most people (myself included) don't even really understand the structure of their identities, much less know the names of them. I know that they identify loosely with large groups, such as Koori and Murri, but I can't even rattle off these broad identities (beyond these two) without looking it up, never mind more specific national identities. Fixing this is on my to-do list, but me learning about it isn't going to change much. I want to see this information floating out there, everywhere, so that if a person takes the time to tell me (or anyone else) who they are, the names they use won't fly away the way unfamiliar terms tend to do. They'll mean something, they'll ring a bell.
I'm also not looking for some grand gesture of massive funding to go out and put a bazillion signs all over the place. Just a commitment to make it happen over time. To start somewhere and keep going until the sign telling me that this is Tharawal land is as familiar as the one telling my I'm driving down Mt Ousley. This isn't history, this is who people are, here and now, and it's shameful that none of know the first thing about them.
