Amy Sherwin could be the most famous Tasmanian you've never heard of... but a memorial project led by former Greens leader Dr Bob Brown aims to change that.

Her remarkable rags-to-riches story unfolds in the 19th century, when a girl from the bush became Australia's first global opera star... known as the "Tasmanian Nightingale." 

• Guest: Dr Bob Brown, President of the Amy Sherwin Fund and former leader of the Greens 
• Producer: Eddy Diamond
