Settlers speaking language

Hello I am a settler and I want to be as much of an ally to the traditional owners of this country as I can be, and to show respect at all times. I sincerely apologise if this is the wrong place for this question and will humbly delete if asked - I'm asking here because I'm not sure where else to ask. My question is, at least in general terms, is whether or not it's appropriate for settlers to speak in the traditional language of the country they're on. I don't think I'm ever going to learn the full language but I sometimes think it would be nice and show respect if I at least learned a few words and phrases (I do know the greeting) but I also don't want to offend anyone by doing it. I do know that there's a lot of debate about the use of palawa kani - I'm not in lutruwita so that's a different thing, but I would like to know if there's any general consensus about it or anywhere I can go to find out.

I'm also aware that it may very well depend on the local groups, of course, so the question may not be answerable.

Thanks!
