I would argue it is because White people are shameless enough to go into Australian politics.....
https://www.bbc.com/news/world-australia-61432762Australia election: Why is Australia's parliament so white?
"Australia is one of the most multicultural nations in the world, but it's a different story in the country's politics, where 96% of federal lawmakers are white.
Some 49% of the population was born or has a parent who was born overseas. In the past 20 years, migrants from Australia's Asian neighbours have eclipsed those from the UK.
But the parliament looks almost as white as it did in the days of the "White Australia" policy - when from 1901 to the 1970s, the nation banned non-white immigrants.
Compared to other Western multicultural democracies, Australia also lags far behind. "
