'A real tragedy': Home and Away stars pay tribute to co-star after death in hospital

She held on for three long weeks, fighting after the crash that killed her parents and sister on Boxing Day.

But on Wednesday morning, Jessica Falkholt lost her battle, with a spokesperson from St George Hospital announcing her death at 10.20am.

At Palm Beach, on the Home and Away set that kick-started a promising career, castmates fell silent, remembering a whole family wiped out in an unimaginable tragedy.

It was a poignant moment for the cast and crew of the TV program that was celebrating its 30th anniversary.

A party was planned, then cancelled out of respect to Jessica and her family.

James Stewart, who acted alongside Jessica, said it was a "bittersweet and subdued" day.

He described his castmate and friend as "really formidable and really bubbly, and she was really kind to everyone."

Pia Miller's character, Kat Chapman, was killed off on the show in a car crash.

"Farewell wonderful Jess," she wrote on Instagram, alongside a striking picture of Jessica.

Jessica Falkholt won acclaim playing Hope Morrison.

In the soon-to-be released Australian thriller, Harmony, she was the star.

"Jessica was a brilliant actress and the film will show the world her talents when it is released," a spokesperson from the film's production company, Cowlick Entertainment, said.

There was no comment today from Jessica Falkholt's extended family, who maintained a vigil at St George Hospital for three weeks.

Jessica was a public figure but they're insisting they want to grieve for her in private.

For three weeks, hope persisted, but it was not enough.

"A massive future. It's such a tragedy. A real tragedy," James Stewart said.
