Cancer-stricken King Charles 'tells aides to supercharge plans for tour of Australia this autumn': Monarch is 'raring to go' and 'feeling positive' after he went on Easter Sunday walkabout amid treatment

King Charles is 'raring to go' for a two-week state visit to Australia after his cancer treatment started positively.

The monarch could return Down Under in just months with Queen Camilla at his side as he prepares for a trip in October.

Charles, 75, is said to be feeling 'optimistic' after he was able to meet with the public on Easter Sunday.

And he has reportedly told aides he is 'supercharging' plans for a two-week trip where he would also visit New Zealand and Samoa.

'The King is raring to go after a significant amount of time off due to his cancer diagnosis,' a source told The Sun.

'He knows he can’t hang around and is feeling extremely positive after tests meant he could attend the Easter Sunday service and spend time meeting the public, which he has missed.

'He’s over the moon with the way treatment has gone and supercharging plans for Australia, New Zealand and Samoa.'

Charles is reported to be feeling 'over the moon' after his cancer treatment has started well.

A source told the paper that he had responded 'very encouragingly' and doctors have since been able to adjust their guidance on what he can and can't do. 

They added that 'the road ahead is looking positive' - although they maintained 'caution is the watchword'. 

But the upcoming tour would have significant differences to the Royals' usual trips - and would include 'significant down-time', insiders say.

The Australian tour is seen as one of the most important for the King, with the late Queen visiting the country 16 times in her reign. 

And more than a year since her death, she remains the only reigning monarch to have visited.

On Tuesday, the King announced the appointment of Sam Mostyn as the next Governor-General of Australia. She will officially take her place in July as the British monarch's representative.

It comes just days after sources claim the King was left feeling 'optimistic' after meeting with royal fans as he arrived alongside the Queen for an Easter Service at Windsor.

While his doctors are keeping a close eye on his health insiders told the paper that he is 'itching to take the reins' and return to his role as King.

And they claim he wants to follow in his mother's footsteps - following her mantra that 'he needs to be seen to be believed'.

No upcoming trips have been confirmed, Buckingham Palace has confirmed to MailOnline.

The King hopes to be back for the Trooping the Colour in June and the 80th anniversary of D-Day in France the week before, The Sun reports, but this is expected to come after his traditional post-Easter break. 

On Sunday the monarch was in high-spirits this morning as he made a 'gentle' return to public life in his most significant appearance since being diagnosed with cancer.

The 'happy' monarch was seen smiling and waving at well-wishers as he arrived in his maroon state Bentley limousine for the service being held at St George's Chapel. 

The King's cheery appearance provided reassurance to the public after he took a step back from his official duties following his diagnosis in February.

Despite the boost to public morale, however, the Royal Family's Easter service looked markedly different to previous years.

Last year, during his first Easter Service as King, Charles led the Firm - including William, Kate and their children - on foot into the service, while this year he arrived by car to shield him from infection during his treatment - as per doctor's orders.

The Prince and Princess of Wales were not in attendance this morning as they continue to recuperate in private after Kate shocked the world with her cancer diagnosis.

In an emotional video, just over a week ago, the Princess asked for privacy as she revealed she would be undergoing preventative chemotherapy. Shortly after, Kensington Palace confirmed that the Waleses would not be attending church on Easter Sunday.
