doog,
Put like you just did it does sound as if it were so. Reality however, is drastically different from every angle. Australia's birthrate is not down, it's the birthrate of the producing wedge of the Demographic pie that is down because of the demands on them. The hangers-on breeders & users are well ahead of the cycle.
I don't know how true some of the statements are regarding the last record intake of migrants but I read that there were a mere 35 trades people among the so-called refugees.
Those sort of figures aren't showing the light at the end of the economic tunnel, they show the lights of the economic train heading for derailment !

Care about Australia ? watch this !

This history of immigration to Australia is very interesting

Every interloper gets a welcome package, priority assistance and centrelink for their 4 wives and 17 children.
Regular Aussies get told "Shuddup!"
While being expected to blindly support things which are not in their interests, from a expected fear of woke name calling.

Wow, the patriotic Left gets more conspicuous by its absence in the comments.
Now, why would that be I ask ?

Some people may identify as immigrants
They may think this country is made up of immigrants
Immigrant Nation!

Others however may take offense at being labelled an immigrant.
I am not necessity what you decide I am.
Not everything was the same in all of Australia.

People in Melbourne have had a much greater ethnic mix than other capital cities.
We do not all live in Melbourne or Western Sydney.
But they went and made the whole entire contry Melbourne and Western Sydney, right out into the regional areas as well.

Immigrant nation my arse.
When I went to school, here was 2 Chinese girls and one from PNG.
The rest of the school was white and I lived in a capital city too.
Not my fault they packed the country like sardines with foreign people, then decided to burn the flag, and relabel the country as a multicultural immigrant nation.

I didn't make the changes, and I didn't change in order to accommodate the newcomers.
I don't have to change who I am to support the hive mind.
