Despite his efforts of philanthropy and activism, the King fails to resonate with young Australians and their values, according to new polling released by the Australian Republic Movement (ARM).

The Pure Profile poll found fewer than 25 per cent of Australians aged 18 to 24 believe Charles represents their values, despite his activism on climate change and other social causes expected to endear him to younger audiences, according to the ARM.

The finding comes as Prime Minister Anthony Albanese announced he will affirm allegiance to King Charles III at his coronation this weekend, even though it is voluntary.

Despite the Australian Constitution Act outlining that a prime minister only needs to take an oath of allegiance when sworn into the House of the Parliament, Mr Albanese is said to be affirming what is considered “appropriate as the representative of Australia”, albeit while maintaining his view that the nation should have an Australian head of state.

This raises the question as to why Mr Albanese will swear “true allegiance”, even though he rebukes the nature of the constitutional monarchy, going as far as to have appointed Matt Thistlethwaite as Assistant Minister for the Republic last year.

The ARM has called on Mr Albanese to not declare his loyalty to the British King but “instead make an anti-pledge”.

ARM co-chair Craig Foster said Australia’s democratic values enable us to be able to decide who should represent us.

“It’s time our head of state was an Australian, chosen by us, accountable to us and serving all of us,” Mr Foster said.

This view is held by many Australians, according to the ARM, yet the failure of the republic referendum in 1999 suggests there are still Australians who believe the country should continue as a constitutional monarchy.

Australian Monarchist League member Jeffrey Fong implores Australians to consider the upcoming coronation as “an opportunity to come together in a spirit of unity with our Commonwealth brethren”.

“I value the stability, tradition and national unity the monarchy affords our country, which would be threatened by a partisan politician as president,” Mr Fong said.

The Monarchist League believes the “current system of governance best defends the democracy of this country” and ensures “politicians are unable to exercise absolute power”.

The historic ceremony on Saturday is the first in almost 70 years and will be filled with traditions passed on through the centuries. 

The Archbishop of Canterbury revealed that the liturgy to be used in the coronation will invite those “who so desire, in the Abbey, and elsewhere” to recite "The Homage of The People". The acclamation declares that the people will pledge their loyalty to the King and his successors. This will be echoed at Westminster, where the coronation has taken place for more than 950 years.

Channels Seven, Nine, Ten and the ABC will televise the event live, with the earliest start at 4pm (AEST).
