At least that's the brutal assessment of Australian prime minister Bob Hawke, played by Richard Roxburgh, in the episode Terra Nullius, which follows the relatively newly wed Charles and Diana on their 1983 tour of Australia.
According to the script, Roxburgh's Hawke has been looking forward to this moment, as he believes it could prove an opportunity to stoke the flames of republicanism already burning Down Under.
But then the pair arrive with their bouncing baby boy, Prince William, and despite a rocky start, the tide appears to turn.
"She's a superstar," Roxburgh's Hawke plainly states to O'Connor's Charles, as the pair watch their wives stroll amongst sprinklers on a clipped green lawn.
"No offence."
The episode shows Charles conceding the point, and begrudgingly chalking it up as a win for his future; the couple had been told that this tour was intended to put republicanism to rest, and it appears as though Diana has done it.
It might not be far from the truth.
An editorial in the March 24, 1983, edition of the Canberra Times declared that "even for committed republicans, and for the many migrants who have no special reason for caring for the British Royal Family, this visit has a reassuring significance".
"This time there cannot be any speculation of a Royal Governor-General; Prince Charles is now obviously too close to accession to the throne.
"This means that during this tour the community can enjoy the spectacle, think a little on the value of a Head of State totally removed from government and political life, and generally be rather more relaxed than at any time since 1975 about considering whether now it wants change."
