my ecology professor is literally teaching that survival of the fittest is about genetic superiority and that evolution is about working towards that 'goal'.

That demonstrates a deep misunderstanding of how evolution works. It is a common misconception in the general public (partly because it is beneficial to right-wing ideology for it to be perpetuated, as you mentioned), but a misconception that even a kinda competent biology layman would know better than to believe. It's nothing short of shameful that an ecology professor is repeating such a thing. To do that as a supposed authority on the subject is actively misleading students, it's worse to teach a falsehood than it is just to leave them ignorant.

I obviously don't know your situation specifically or how things like this work in Australia, but if I were still a student and my prof was saying those things, I would definitely complain about it to the department chair or someone who has the power to intervene. I don't know if your professor is just woefully uninformed/misinformed on the subject they're teaching, or if they're repeating this misconception because they have a reactionary political agenda. But either way it's horrible and shouldn't be allowed to stand imo.
