The Great Barrier Reef (GBR) is under pressure from climate change and other threats, and part of the solution is to raise awareness of the GBR and its threats beyond a local audience (Great Barrier Reef Marine Park Authority, 2019). Reef HQ Aquarium (the national education centre for the Great Barrier Reef Marine Park Authority) implemented a virtual marine education program focussed on the GBR in 1998. The program uses videoconferencing technology to connect real-time marine biology experts to participants around the world. We report on > ten years of participant trends for this program to assess whether the program is a mechanism for increasing community educational outreach. Since 2005, the program increased the Aquarium's community and educational outreach by 4.8% by connecting an additional 83 388 participants from 19 countries worldwide. While the videoconference technology has evolved overtime, the program content remains a unique, interactive virtual experience that has proven to be an effective way for an informal learning institute to increase their outreach on a national and international level, particularly as there has been a transition to online learning and educational programs due the recent global Coronavirus pandemic.
