Kate was born into the wealthy McElhaney family. Her father was a property developer, her mother an upperclass housewife with a love of gin and gossiping with other ginn'd up housewives in Melbourne's affluent eastern suburbs. She attended an all-girls magical primary in the city, before graduating to Penrose at the age of eleven.
It was during her years at Penrose that she got bored with being a good daughter. She discovered a penchant for playing with people's reactions, and took up several bad habits - smoking, sneaking into Greyheme, playing pranks on the professors, skipping classes and drinking on school grounds for the fun of it... but her parents were too wealthy for even the school to disagree with her behaviour, and her excuses were so innocent and her apologies so sincere she was never given more than a warning for her actions.
She first met Alan at an inter-school event, where their scandalous relationship ended abruptly as the pair returned to their respective schools. Two years later, they reunited in Melbourne while at uni, and dated seriously for three years. When it seemed that Alan was ready to pop the question, Kate left him - instead marrying Seth Rice, a man her father approved of. Their relationship lasted three years, and once her divorce was settled, she took to casually seeing Alan once more.
She made her way to Headmistress of Penrose, through money and sabotage, but always kept tabs on Alan. Their twisted romance was talk of the halls more than once at Penrose, and though they tried being serious again - nothing ever worked out.
In late 2008, Kate started seeing Alan's best friend, Matthew Longhurst, after he dared her to try and hook up with him. The pair fell in love accidentally, and married in a surprise wedding on the Murray. Matt's much younger half-siblings Aiden and Valerie moved in with them shortly after the wedding.
Kate changed her surname again from Longhurst to Belmont, when her husband chose to use his mother's maiden name rather than the surname he was born with. After a very difficult pregnancy, the pair had a daughter, Hazel, who would have been followed by a second daughter, Rylea, but this time the difficult pregnancy was too much for Kate to handle and the baby was lost as a result.
The Belmont's problems escalated further still when Matt was hit by a tram in the Melbourne CBD, and has been in a coma since. Matt's brother Adam took custody of Aiden and Valerie, as Kate began to lose interest in the world outside of her work, her daughter, and the desperate hope that Matt would wake up. She moved with Hazel back to Melbourne and rarely comes to Narrie, as the memories in town are too painful for her most days.
