Sean Coughlan Royal Correspondent Welcome to Royal Watch. King Charles and Queen Camilla have finished their Australian tour, with big crowds greeting them outside the Sydney Opera House on their last day, and are now in Samoa for the Commonwealth summit. More on the indigenous senator who heckled the King below. ‌ Meanwhile back in the UK, we’ll hear about a project close to Prince William’s heart. And that’s not just his football team Aston Villa.

What legacy for the royal tour?   What makes a royal visit a success? When does it become a more complicated story? Buckingham Palace will have been delighted that the King and Queen got such a warm welcome from crowds gathered in the Australian sunshine. ‌ The royal couple covered a wide range of engagements over a few days - everything from formal meetings with politicians, to social housing projects, meeting the indigenous community, attending a naval review and a community barbecue.

There were times earlier this year when it would have been seen as an achievement that the visit went ahead at all.

Those big media moments go round the planet so far and so fast - the kind of lightning-bolt event that gives nightmares to spin doctors. With a few shouted words it opens up the whole debate about republicanism and the treatment of indigenous people.  ‌ With the Australia trip over, the palace will be hoping that the gentler, warmer welcomes will be remembered - rather than any protest. The King is now in Samoa for the meeting of Commonwealth leaders - with some countries planning to raise the issue of reparations over the transatlantic slave trade.
