I had to look up the speech to check if this was an accurate representation or whether that ellipsis was doing a lot of work, and while it's not verbatim, it's very much close enough:
In the 2021 census, more than half of Australian residents, 51.5% were born overseas or had one parent born overseas.
51.5%.
Is that what supported by the Australian electorate? Is that what Australia wants?
The whole "we need to make it easier for bosses to fire workers" thing also seems like it should have tanked..
