Fiona MacDonald knows that time is running out, but she's not sitting still. Against all advice, the former TV personality set off earlier this year on a "Thelma and Louise" style road trip around Australia with her sister Kylie Thynne. Almost two years ago, at the age of 64, this bubbly extrovert was diagnosed with motor neurone disease, an illness which robs its victims of speech, mobility and eventually their lives. It's a disease with no cure. Determined to make the most of what time she has left, Fiona is raising awareness of the disease and money for MND research as she circumnavigates the country. Australian Story follows the sisters on this heart-warming, funny and emotional journey of a lifetime.
