Jocelyn Moorhouse and PJ Hogan are two of this country's most celebrated movie directors. The success of their debut films had Hollywood calling and they have since worked with some of the biggest names in film.

They are also the parents of four children, two of whom have severe autism. And the experience of raising those children has shaped their personalities and careers.

Jocelyn gave up her career to concentrate on her son and daughter's therapy. She didn't expect to direct again.

But in 2015, 18 years after making her last film, she made a triumphant return with The Dressmaker.

In this intimate portrait, the family speaks candidly about the challenges, heartbreak and unexpected joys of living with two severely autistic children.

When 21-year-old Menindee farmer Kate McBride came across thousands of dying fish in her beloved Darling River she was determined to tell the country what was happening.

She posted the pictures on her family's Facebook page and the images went viral.

"I don't think there's a way to put into words what seeing millions of dead fish on the river that you've called home for your whole life is," she remembers. "It was just pure devastation… these animals were suffering."

By the time truckloads of fish were disposed of at the town dump, Kate was emerging as a fierce advocate for the health of the Darling River and a leader to watch.

She's been documenting local health concerns about water supplies from the river and is pushing for a Federal Royal Commission.
