Andrew Moffat

Andrew Moffat’s 12 years as a Director of Vision Australia – the last eight as Chair – have given him deep insights into the strategic and operational challenges of the disability sector, during a time of profound change for organisations and the clients they serve. Andrew has led large commercial businesses, but the for-purpose sector – with its complex interplay of stakeholders and often unquantifiable outcomes – makes leadership in this space especially demanding. The creation of the NDIS, aged care model changes, and responding to COVID added further challenges during his tenure as Chair.

Andrew studied both Law and Commerce degrees at the University of Melbourne, then moved to London to begin his career as an investment banker. Andrew worked with governments, private companies and financial institutions to secure funding for businesses and projects across the world, including for renewable energy businesses in India and Germany. After returning to Australia in 2005 – now with three children – Andrew became a commercial banker at two of Australia’s major banks, arming him with an understanding of financial and strategic challenges for Australian businesses.

Andrew’s for-purpose governance experience began when he joined the board of a large UK blindness organisation in 2001, and this role naturally fed into his Vision Australia leadership once back in Australia. Before leading the whole organisation, Andrew served as Chair of the Vision Australia Foundation and Chair of the Audit, Finance and Risk Committee, giving him close exposure to the financial challenges of the sector, and how to manage them effectively. Andrew has also taken leadership roles in the sport sector, as Chair of the Coaching and Development Commission of the cycling governing body, and as President of Australia’s leading fencing club.

In 2012, Andrew established his mediation practice. He is brought in when disputes emerge, sometimes within, and often between, organisations. Andrew’s experience of the for-purpose world – often characterised by huge passion for mission, but too little resource and infrastructure – has led to his appointment in many disputes within the sector. Andrew is now a Senior Fellow of the Melbourne Law School, teaching Mediation in the Juris Doctor and Masters programmes.
