He will be just one of three young West Australians and 1000 young delegates worldwide to attend the One Young World Summit in Dublin in October.
Founded in 2009, the UK-based One Young World gathers the brightest young people from around the world, empowering them to make lasting connections to create positive change.
All delegates are leaders in their community and debate, formulate and share innovative solutions for the pressing issues the world faces.
Past Summit counsellors have included Bill Clinton, Archbishop Tutu, Sir Richard Branson, Bob Geldof and Jamie Oliver.
Mr Williams is passionate about building stronger, healthier and happier communities.
As chief executive of Community Solutions, he works with local communities to respond to community challenges.
‘The Summit is a huge opportunity for someone born and bred in Mandurah to help create a global network of young leaders,” he said.
After the Summit, delegates are then known as One Young World ambassadors who work on their own initiatives or lend the power of the network to those initiatives already in existence.
The 26-year-old hopes to help bring the 2017 One Young World Summit to Australia.
