Introduced by Australian of the Year, Adam Goodes.

Explorer and airline pilot Percy Trezise was captivated by Quinkan rock art fifty years ago when road workers stumbled across an ancient painting.

The Quinkans are now rated among the most impressive and ancient rock art in the world. They became an obsession for Trezise – a passion passed on to his two sons.

Percy recorded stories from the elders and worked closely with legendary artist Dick Roughsey to protect the fragile paintings, hidden amongst the sandstone escarpments near Laura in Far North Queensland.

Now his sons, Matt and Steven Trezise, are at a crossroads as they contemplate their own uncertain future after years guiding visitors into the rock art sites and managing their father's legacy.
