WATCH: King Charles confronted by Australian senator in verbal attack
During the visit Charles will meet colleagues Professor Georgina Long and Professor Richard Scolyer, named as Australians of the year 2024 in recognition of their pivotal work on melanoma, one of Australia's most common cancers.
Other highlights of the Australian visit will see the royal couple spending time in the capital Canberra meeting leading figures and paying their respects to the country’s fallen, while in western Sydney they will attend a community barbecue – a staple of Australian culture.
The King and Queen will later travel to Samoa for a three-day state visit and meet world leaders taking part in a Commonwealth Heads of Government Meeting which Charles will formally open.
Take a look at the best photos from their official trip…
The drizzle didn't dampen Queen Camilla's spirits as she arrived in Sydney wearing a royal blue Fiona Clare dress, adorned with the Australian wattle brooch and her Charlotte Elizabeth 'Mayflower' bag.
After the service the royal couple went outside the church to shake hands with the well-wishers, who numbered around two hundred people, with some waiting since 5am to catch a glimpse of the royals.
On Monday, the King and Queen arrived in the Australian capital, Canberra, where they were greeted by Ngunnawal Elder Auntie Serena Williams, a representative of the Indigenous people.
The King was understood to be "unruffled" by the outburst from Senator Lidia Thorp at Australia's Parliament House, who told him, "You are not my King". In Charles' address, he spoke of his affection for the nation and acknowledged the "timeless wisdom of Indigenous people".
The King shook hands with Australia's prime minister Anthony Albanese at Parliament House.
Mr Albanese said of the monarch before his speech: "You have shown great respect for Australians even during times when we have debated the future of our own constitutional arrangements and the nature of our relationship with the crown. Nothing stands still."
The Australian National Botanic Gardens - Canberra
After separate engagements, the King and Queen concluded their visit to Canberra with a walk around The Australian National Botanic Gardens, which boasts the largest collection of Australian plants in the world.
