Having resided in a country town for about 15 years, racism or discrimination (depends on what you see it being in the circumstances) was rife.
For example, an (Australian) man coming to live in the town (with wife and 2 children) was denied work, not because he didn’t have the qualification, but because as one woman made clear, he might ruin the tractor on their farm. What it really was about was racism of country versus towns people. When he finally got himself a job, his then employer praised his abilities. Still, within a year the family moved back to Melbourne, as the ongoing racism continued. Taunting the children ,and the wife in shops, that they ought to go back where they came from (Meaning Melbourne), etc, finally was too much for them to bear!
Racism doesn’t mean it has to be against a person of different colour of skin!
It is not just against Indigenous people!
I have never known such a bunch of egoistic, racism lot of people as in that town!

Having lived in Melbourne for about 18 years in total, besides visiting it about weekly in an additional 15 years, I for one found no such kind of discrimination/racism! Perhaps that most people all are in the same situation that you are or you know someone who is from a different area and hence people help each other out.
When visiting Adelaide, for the first time in 1980, I found the people there very spontaneous, very warm towards newcomers, and absolutely no trace of racism, etc.

Remarkably the very towns dying out because people are moving out, rather then moving in could reverse this tend to some degree by not being racist!
