Lindsay Oxlad
A life of service to better transport
An abridged version of the eulogy delivered by Andrew Leedham, Life Member TPA on behalf of TPA, ATRF, TAS and ITE-ANZ
For more than four decades, Lindsay Oxlad profoundly shaped the way transport planning and policy is understood and practised in Australia. An engineer, transport planner, transport modeller, policy adviser, mentor and trusted colleague, Lindsay’s influence extended well beyond the projects he worked on or the roles he formally held. His legacy lives on in the standards he championed, the people he supported, and the institutions he helped strengthen across the transport profession. Lindsay dedicated almost 40 years of service to the South Australian Public Service, working across the State’s road and transport planning functions, now part of the Department for Infrastructure and Transport. Over a career spanning more than 45 years, he became widely respected not only for his technical depth, but for his integrity, intellect, generosity and unwavering commitment to the public good.
A distinguished career across engineering, planning and policy
Lindsay’s professional journey covered an extraordinary breadth of roles and disciplines. He worked as an engineer, transport planner, transport modeller and policy adviser with both State and Commonwealth Governments. Prior to his retirement from the South Australian Government in 2016, he served as Manager of Road Transport at the Department of Planning, Transport and Infrastructure. In this role, he led a specialist team responsible for developing strategic transport planning models, shaping medium - and long-term transport policy, and overseeing High Productivity Vehicle road and route access across South Australia.
Throughout his career, Lindsay built and applied a remarkable range of skills. He was deeply experienced in project and risk management, corporate governance, strategic planning, transport and land use integration, transport modelling, and policy analysis. Colleagues often remarked on his ability to navigate the complexities of government decision-making while remaining grounded in evidence, clarity and purpose.
Academically and professionally, Lindsay’s credentials were extensive. He held a Master’s Degree in Engineering (Transport and Traffic) and a Bachelor’s Degree in Civil Engineering. He was a Registered Professional Engineer, a Chartered Professional Engineer, an APEC Engineer, a Chartered Member of the Chartered Institute of Logistics and Transport, and a Fellow of Engineers Australia, the Australian Institute of Company Directors and the US Institute of Transportation Engineers. Yet for all his qualifications, those who worked with him knew that Lindsay never relied on titles alone - he let the quality of his thinking and the strength of his arguments speak for themselves.
Advancing transport modelling and evidence-based decision-making
One of Lindsay’s most enduring contributions to the transport profession was his leadership in advancing transport modelling as a core component of sound policy and investment decision-making. At a time when modelling was often met with scepticism - particularly in environments dominated by hands-on engineering and construction perspectives- Lindsay remained steadfast in his belief that robust modelling was essential to understanding future demand, testing options and justifying major infrastructure investment.
During his time in the South Australian Public Service, he worked tirelessly to build modelling capability within government. He helped establish teams from the ground up, fostered close collaboration with universities, and later supported the engagement of consultants to develop and apply the state-based travel demand model, MASTEM. His vision was not modelling for its own sake, but modelling as a rigorous, transparent foundation for better decisions - particularly for major road and public transport projects requiring strong economic and policy justification.
This work was not always easy. Lindsay often worked among peers who were, as he himself would jokingly acknowledge, more comfortable with “dirt and rocks” than abstract models. Funding was limited, and new approaches were not always welcomed. Yet through persistence, conviction and, when required, forthright advocacy, he helped change minds. What was once questioned has since become standard practice: transport modelling is now recognised as essential to developing strong business cases and guiding long-term infrastructure strategy. That shift is a central part of Lindsay’s professional legacy.
Leadership, mentorship and high standards
To work with Lindsay was to understand that his trust had to be earned. He set high expectations and held himself and others to them - not out of ego or inflexibility, but out of a deep commitment to quality, credibility and public value. As he saw it, transport decisions carried long-term consequences for communities and economies, and therefore demanded the highest possible standards.
One colleague, who worked closely with Lindsay over many years, reflected on this approach:
“Lindsay never failed to express critical advice and guidance on project conduct and outcomes. He was typically forthright on project delivery, including both consultant and departmental inputs. You knew exactly where you stood with his delivery expectations.”
Others recalled that while Lindsay could be demanding and meticulous, he was also generous with his time, thoughtful in his guidance and deeply invested in helping colleagues grow. Many described him as a wise mentor, particularly for those working in planning and policy roles, and a strong supporter of the next generation of transport professionals.
Former Director General of Transport Derek Scrafton remembered Lindsay’s exceptional project management skills during the rebuild of the North Adelaide Swimming Centre in the 1980s, as well as his ability to work effectively with Ministers and Departmental CEOs. It was a skillset not everyone possessed, and one Lindsay exercised with quiet confidence. At the same time, colleagues fondly recall his ready laugh, twinkle in the eye, and ability to bring warmth and humanity to even the driest technical discussions.
A deeply engaged professional community contributor
Lindsay’s commitment to the profession extended well beyond his formal government roles. He was an active and long-standing member of several key professional and technical organisations, including the Australian Institute of Traffic Planning and Management - now the Transport Professionals Association (TPA) - the Australasian Transport Research Forum (ATRF), the Transport Australia Society (TAS), and the Institute of Transportation Engineers – Australia and New Zealand (ITE-ANZ). Through these bodies, he gave generously of his time, insight and resources.
Within AITPM/TPA, Lindsay played a particularly important role in the early development of the Transport Modelling Network. As a member of its inaugural national committee, he helped lay the foundations for what has since become the principal professional home for transport modellers across Australia. His contributions were both practical and strategic, shaping the network’s direction, standards and culture. Today, its strength and influence stand as a lasting testament to his involvement.
He also served on multiple AITPM national conference committees, reviewed countless technical abstracts and papers, and quietly provided financial support to conferences, state branch activities and Transport Modelling Network events. Those gestures reflected a deep and genuine commitment - not just to technical excellence, but to sustaining a vibrant, connected professional community.
At events, Lindsay was a familiar presence, often seated near the front. He was rarely without a question - always thoughtful, always well considered, and invariably designed to test the rigour of what was being presented. As many speakers can attest, there was usually a glint in his eye and a faint smirk as if to say, “Let’s see how you go answering that.” Yet there was never malice in it. His questions were an expression of care for the integrity of the profession and a desire to see work that was sound, credible and worthy of its consequences.
The man behind the professional
Colleagues and friends consistently described Lindsay as fiercely intelligent, deeply curious and meticulous, yet also warm, humorous and generous of spirit. He was often labelled a perfectionist and, at times, challenging to work with. But almost invariably, people added that any difficulty was outweighed by the respect and satisfaction that came from working with someone so deeply committed to quality and the public interest.
Many remembered his extraordinary work ethic - sending emails late at night or in the early hours of the morning long before remote working became the norm. Others spoke of him as a gentle soul with a big heart, a fun-loving traveller, and a devoted family man. Across all these reflections ran a common theme: Lindsay always acted in the best interests of the organisation and the community he served. He had no hidden agenda, only a steadfast desire to achieve the right outcome.
A lasting legacy
By the time he retired from the South Australian Public Service in 2016, Lindsay Oxlad had become a pillar of the transport engineering and planning community in South Australia and beyond. His leadership helped shape not only major projects, but the standards by which transport work is conceived, assessed and delivered.
Through his commitment to evidence, integrity, mentorship and professional service, Lindsay made the transport profession stronger, more credible and more connected. Above all, he genuinely wanted to make the world a better place. Through his work and his example, he undoubtedly did - leaving the profession, and the communities it serves, better than he found them.
Beyond his professional life, Lindsay was, above all else, a devoted family man. He was very proud of his three children - Helen, Vanessa and David - and their partners, and spoke of them often. He greatly valued time spent with his grandchildren, who were a quiet source of joy for him throughout his life. Family mattered deeply to Lindsay, providing perspective and balance, and those who knew him understood how important his role as a father and grandfather was to him. In this way, his legacy endures through the values, care and integrity he passed on to those closest to him.
