Overall, Australians are very much split in their opinion when it comes to the monarchy. Roughly half (54%) agree that following the end of Queen Elizabeth II’s reign, Australia should end its formal ties to the British monarchy. However, 46% disagree. Respondents under the age of 50 are more likely to agree – 65% of 18-29 year olds and 59% of 30-49 year olds agree that links should be severed, compared to 49% of 50-64 year olds and 53% of those over the age of 64.

This poll is from the end of 2022, before the release of Prince Harry’s book “Spare.”

What’s significant about this is that opinion polls in Australia (and New Zealand) have shown an increase in support for the monarchy post the end of Queen Elizabeth’s reign. This is to be expected given the amount of positive media exposure the monarchy has had. However, that exposure has waned and clearly support for a republic is back on the rise.
