Like (eg.) RMIT or CQU doesn't open any doors in Vietnam, India, or Indonesia, but all their advertising (which often includes calling out immigration) essentially devalues the reputation of Australia's education system in those countries.
It's the same thing in Canada and the UK.
For example, a Masters in Project Management [0] or Information Technology [1] from CQUni that ends up costing AUD 80k-100k in tuition, fees, and living costs isn't opening any doors professionally in the old country nor in Australia.
But they won't.
Same goes for Canada and the UK.
