Geraldine supports several animal welfare and environmental organizations through the donations of her art. Closest to her heart is Friends of the National Parks Foundation (http://www.fnpf.org) in Borneo, Indonesia, which focus on the conservation of orangutans and other Indonesian wildlife. When FNPF worked on rescuing and rehabilitating orangutans, Geraldine had the exciting opportunity to visit the rehabilitation centre. That experience became the catalyst for her mission to raise funds and awareness for endangered wildlife.

"I remember how heavy and steamy the air was as I walked toward one of the enclosures. The heaviness eased when my eyes met the most loving, big brown eyes I had ever seen. That love shining from her eyes will stay with me forever - the key to unlocking the personality and sentience that I burn to express through each of my portraits."

Stirred by this life-changing trip, Geraldine founded the “Riding for Rangas” annual charity bike ride in 2009 (biennially since 2013) to raise funds and awareness for FNPF. Riders sponsor to complete the challenging 300km distance in two days.

Geraldine has accepted many invitations to donate her works to significant animal conservation groups and campaigns such as Humane Society International, ENDANGERED Art4Apes Fine Art and Photography exhibition, Sketch for Survival in conjunction with Explorers Against Extinction, Sea Shepherd, Silvery Gibbon Art Auction and Borneo Orangutan Society.

The spring of 2019 and the summer of 2020 was the most catastrophic Australian history of bushfires and the consequent loss of a staggering 480 million animals and 18.6 million hectares of habitat. Prompted by this and unable to sit still, Geraldine took it upon herself to set up an online Facebook silent auction of one of her koala drawings to raise funds for the Port Macquarie Koala hospital in NSW. Through the connection of social media, Geraldine's page was discovered. She was invited to participate in "100 Artworks for a Koala - Konservation Project" through the nonprofit organization Living With Koalas. 100 Australian based artists will provide original artwork relating to koalas. An auction led event on an international scale, funds generated will be used for awareness programs and school visits and funding LWK koala food tree nurturing and planting. Originally planned for 2020, the event will go ahead after Covid restrictions have eased.
