Cameron Walker forced to 'completely scrap' plan during Royal Tour - go behind the scenes in Australia

Hundreds of well-wishers had greeted the royals in Sydney yesterday, as the King and Queen attended church.

While on the media bus to Canberra Airport, Cameron greeted GB News members and proceeded to reveal what was in his lunchbox.

Ahead of the King and Queen's arrival at Canberra Airport today, Cameron shared another sneak peek behind the scenes.

Pictured alongside members of UK and Australian media, he explained the royals would arrive within the next half an hour or so.

"There are school children from lots of different schools in Canberra, who have come here and lined up, hoping to chat to the King and Queen, if they go and greet them."

Cameron explained it was the middle of the night in the UK, so they wouldn't be appearing live on GB News at that point in their day.

"There's a lot of waiting around for a royal engagement but it's always worth it in the end," he said.

Having arrived in Canberra, King Charles and Queen Camilla visited Australia’s Parliament House for a Ceremonial Welcome and Parliamentary Reception.

The King delivered a speech at the event, but it was interrupted by Victoria Senator, Lidia Thorpe, who chanted: "You are not our King, this is not your land!”

In another behind the scenes video, outside Parliament House, Cameron explained he was working to a "very, very tight deadline", as he reported on the protestor's unexpected outburst.

"I had to completely scrap what I was planning to do today to send back to Breakfast, and basically start again."

The correspondent explained the team would then board a flight back to Sydney, before speaking to Andrew Pierce live on Britain's Newsroom.

A royal source told GB News: “Their Majesties were deeply touched by seeing and hearing the very many thousands who’d turned out to support them, and are only sorry they didn’t have a chance to stop and talk to every single one.

“The warmth and scale of the reception was truly awesome. While they are grateful to all the crowds, Their Majesties particularly enjoyed hearing individual stories of those who’d made such a special effort to be there.”

Cameron later shared a glimpse of the Sydney skyline from the air ahead of the aircraft landing in the city.

"We jumped on a flight straight after we filed for Breakfast, back to Sydney, because we've got to do some more lives for Britain's Newsroom," he said.

"Then we're going to go to sleep because it's another grilling day in Sydney tomorrow for the King and Queen, and us who have to follow them around, covering them."

Cameron Walker reflects on day ahead of full day of royal engagements in Sydney

After a busy day with unexpected breaking news, Cameron shared his final message of the day, standing in front of a fireworks display by Sydney Opera House.

"Look at that. We have just finished our last live and a firework display has just started outside the Sydney Opera House. It's been an incredibly long day but it's been an incredibly rewarding one. Really really fun.

"We recorded a couple of 'as lives' which is where it looks like it's live to you guys at home but it's not, it's recorded ahead of time, so programmes can play it out when we are asleep, because obviously Australia is a different time zone to the UK.

"Tomorrow, another full day of engagements in Sydney. Not sure if there are going to be more fireworks, we will have to wait and see."
