The style is described as a combination of indigenous dot painting and op art illusions with surreal qualities. As of 2008, Murdoch exclusively showed his work at the Bowraville Art Gallery.
Describing Murdoch"s work, gallery curator Darren Green has said “there is nothing else like it in this world."
Although not a qualified teacher, Les has also been involved in a mentor program through the Junuy"s Aboriginal Youth Project where he has personally encouraged aboriginal youths to pursue their love for art
