Apparently the answer is yes. From the AFR:
Everyone knows John Kinghorn pocketed $650 million from the controversial 2007 float of Rams Home Loans.
What is less known is that he is in the process of giving away almost half the money.
Following what was dubbed the worst initial public offering of the decade, the RAMS founder sank $300 million into the Kinghorn Foundation, turning his family charity into one of the largest private foundations in Australia. Now, he wants to help cure cancer.
He has given $25 million and his name to the Kinghorn Cancer Centre, an initiative of the Garvan Institute and St Vincent’s Hospital, which opens to the public next month.
He plans to donate substantially more to the centre’s next big project: a gene-mapping facility to help predict disease, more precisely diagnose individual cancers and better tailor treatments to patients.
Good on him.
