‘Billionaire biffo’ shines light on hugely ambitious $30bn solar project

The row between Mike Cannon-Brookes and Andrew Forrest over Sun Cable reveals the technical, economic and even geopolitical hurdles to completion

Behind the “billionaire biffo” between Mike Cannon-Brookes and Andrew Forrest over the future of Sun Cable is a project that has analysts dubbing “visionary” but also “extremely ambitious”.

In Australia’s first big business story of the year, Sun Cable was placed into voluntary administration on Wednesday. That signalled the company won’t be able to meet debt payments without another injection of funds said to be $60m, with Forrest the one not “aligned” with other investors in a willingness to dig deep again.
