Support for Australia Day on 26 January has surged, yet again, with more than three-quarters of Australians backing it in, including 83 per cent of Australians aged 18-24
The IPA is a right-wing think tank that pretty much exists to mislead the public, so take this data with a grain of salt.
Yeah I could tell but it looks like the polling was done by independent polling company:
The IPA has today released a new poll of 1,011 Australians, undertaken by independent marketing research firm Dynata, on their views about our national day.
So I assume how it works is, they get this company to ask a bunch of questions on a bunch of topics they want to push, if the poll results come back negative for them (eg. more people are concerned with climate change than before) they just discard it, and if they come back positive they then publish it
