King Charles has reportedly ordered aides to step up plans for his two-week state visit to Australia.
Charles, 75, is said to be "over the moon" and "raring to go" after starting cancer treatment in the winter.
He is hoping to return to Australia with Queen Camilla in October and wants to visit New Zealand and Samoa. However, a stop in Fiji has been ruled out.
It is expected the royal tour will feature "significant downtime" to allow the King to lead the Commonwealth Heads of Government Meeting.
A Palace insider told The Sun: "The King is raring to go after a significant amount of time off due to his cancer diagnosis.
"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.
"Although his doctors are keeping an eye on his health, he's itching to take the reins and get back to his public role as Head of State.”
Charles also wants to be at the Trooping the Colour and the 80th anniversary of D-Day in France in June.
It comes after the King thrilled hundreds of royal fans at Windsor after making a public appearance on Easter Sunday.
He was cheered and applauded as he emerged from St George's Chapel with the Queen to cries of "Happy Easter!"
Urged by one bystander to "Get well soon!" Charles quipped "I'm doing my best!" as he brushed off guidance and shook hands with the crowds.
