About Sun Cable
Sun Cable was founded by David Griffin, Mac Thompson, and Fraser Thompson with a vision to revolutionize the renewable energy sector.

In its journey, Sun Cable attracted attention from major investors, including Australian billionaires Mike Cannon-Brookes and Andrew Forrest. The project promised not only to supply clean energy but also to position Australia as a leader in renewable energy exports.
However, the path was not without challenges. In 2023, Sun Cable faced financial difficulties, leading to its collapse. This pivotal moment opened the door for Mike Cannon-Brookes, co-founder of Atlassian, to acquire the project. His acquisition marked a new chapter for Sun Cable, ensuring the continuation of its groundbreaking vision.
Sun Cable's story is a testament to the potential of renewable energy and the importance of visionary leadership in overcoming obstacles. The company's journey underscores the transformative impact of sustainable energy solutions on a global scale.
