Gillie and Marc’s passion for wildlife and conservation lead them to immediately accept their invitation to paint one of 45 public sculptures as part of Taronga Zoo’s Wild Rhino exhibition that ran from February to April in 2013. The exhibition introduced 45 Rhino sculptures to the streets of Sydney, each of them adorned with an artistic flair from a local artist. All profits from the auctioned sculptures went to Taronga Zoo’s Rhino breeding and conservation programs. Their contribution focuses on the nature between humans and animals; as zygotes in the womb all animals (including humans) look the same. Gillie and Marc also wanted to draw attention to the estimated figures that annual Rhino death rates will soon overtake their birth rates.
