Further $100m donation to ANU scholarships

He's already given millions to bring Australia's top students to ANU and now Graham Tuckwell will help house them too.

The multimillionaire securities trader and wife Louise are building on their $50 million gift in 2013 to pay for two new residential halls to be built at the Australian National University, at a cost of about $100 million.

Revenue from the halls, which will each house about 400 students, will be used to fund the Tuckwell scholarships in perpetuity.
