Former prime minister Malcolm Turnbull and Canva co-founder Cameron Adams have joined Rich Lister Mike Cannon-Brookes and government innovation funds on the share register of Australian solar disrupter SunDrive.

Mr Turnbull said he participated in the latest funding round for the pre-revenue solar start-up because he believed SunDrive’s technological breakthrough in solar cell manufacturing could be a “game changer” for the photovoltaic industry.
