THE AUSSIE AFFAIR HE TRIED TO HIDE

While in Oz, the heir began a secret romance that would end in tragedy

King Charles reportedly once said that Lady Dale "Kanga" Tryon was "the only woman who ever understood me", but even while their love affair was scandalising English high society, the royal was also sleeping with the woman who would become his queen.

It was an epic tug of war between Kanga and Camilla Parker Bowles that played out during the 1970s, and while Camilla eventually won the battle royal for King Charles' heart, and is now his queen, many don't know that for years he kept both women as mistresses, and reportedly "bounced from the bed of Camilla to that of Lady Tryon, then back again".

The passions bubbled under the surface even after Charles married Princess Diana in 1981, with the women continuing to dislike each other.

So how did a little-known Australian woman from a wealthy Melbourne family end up marrying a peer and falling in love with a prince?

Kanga met Charles in 1966 while the teenage prince was studying for two terms at Geelong Grammar School in Victoria, but the legendary affair didn't start until after she married blue-blooded banker Lord Anthony Tryon in 1973.
