In 1997 one of the great mysteries of Australia's Kimberley region was finally solved when the mysterious rock paintings, described and documented by pastoralist Joseph Bradshaw during his 1891 Prince Regent River expedition, were eventually located. In Joe's footsteps, over 100 years later, John Bradshaw embarks on A KIMBERLEY ADVENTURE with fellow rock art enthusiasts Adrian Parker and Chris Done to view the elusive galleries that have remained an enigma for decades; their location, still to this day, a closely guarded secret.
