In 2013 the Ethics Olympiad was created by Matthew Wills the then Head of Philosophy and Ethics at Hale School in Perth Western Australia based on a similar competition in the US called a US Ethics Bowl. School-based teams are scored by judges on their responses to ethical questions. In 2020 the Ethics Olympiad moved online due to the impact of COVID-19 restrictions and is now run annually for Senior, Middle and Junior schools. 
Since 2019, the Ethics Olympiad has been conducted in capital cities in Australia and New Zealand. Schools enter a team of 5 students or two teams of 5 students. Team scores are collated over three heats and then the top two schools play-off for the Gold and Silver medal while the third-placed team receives the Bronze medal. In 2020 due to Covid restrictions the event went back online using Zoom. This made it possible to run International Olympiad Finals.
