In this extended episode we share a recording from the opening plenary session at Digital Twin Week 2021. Moderated by Gavin Cotterill (Consulting Director Asia Pacific, PCSG), this dialogue followed a keynote presentation from Romilly Madew AO (CEO of Infrastructure Australia) that shared key outcomes and recommendations from the recently released Australia Infrastructure Plan, including gits call for the nation's infrastructure to be 'digital by default'. This panel session was a response to that aspiration, with three industry leaders coming together to unpack what that might mean. The panel guests were Richard Morrison (Practice Lead Information and Communications Technology ANZ, AECOM), Meredith Hodgman (Associate Director Places and Partnerships, KPMG) and Henry Okraglik (Global Director Digital, WSP).
