You, as a teacher of, what, more than 30 years, spent how much time teaching in a remote Aboriginal community?
I ask this because there are many teachers that ask to be posted to them.
One that I have visited several times is Jigalong, about 80 km east of Newman in WA. The teachers live in a compound, for their own security. I suspect you would not have the bottle to be posted to such a place.
