René grew up surrounded by forests in the province of Utrecht in the Netherlands and Nelleke grew up in Apeldoorn. Her father was the director of national parks for the region which included the parklands ‘de veluwe’ and ‘de apenhuel’, so both spent a lot of time in nature. But it was the beautiful tropical, yet cool climate of the Atherton Tablelands that drew them to this area. Since arriving in the early sixties, they have spent a lot of time in the Queensland bush, camping by rivers, fishing and of course fossicking. They have always adopted a ‘leave only footprints behind’ approach to the natural world around them.
Today, they live in a single bedroom bali style home with large sliding doors that rarely close. They live in harmony with insects, snakes, spiders, bats, possums and wallabies. They have always taken a keen interest in the world around us and the environment that we live in.
René and Nelleke’s daughter Ghis takes that approach to another level. She and her husband live off the grid on a farm and actively observe sustainable living practices in everything they do. Since taking over management of The Crystal Caves in 2014, Ghis has improved the day to day efficiency of the operations starting with a new track lighting system that replaced hundreds of 150 watt incandescent spotlights to 4 watt led lights that reduced the electricity output to a third. The roof was insulated with wool batts and energy efficient air conditioners replaced old models. Over the years, many renovations have taken place and any building materials that come out of the building are donated to the local men’s shed or recycled into fixtures and fittings in the shop. All our display benches are made from an internal wall framing and our glass display cases are from a closed down décor shop in Spence street, Cairns.
In 2023, we signed up to the ecoBiz program which is funded by the Queensland Government to support businesses to further improve their energy, water and waste efficiency and we are getting down to the nitty gritty of the little things to continue to care for our planet.
