Former Australian Ambassador to the United States, the Hon. Arthur Sinodinos AO, delivered a timely and insightful address at an exclusive business luncheon hosted by Business Sydney and Sparke Helmore Lawyers on Tuesday, June 17, at Martin Place in Sydney.
The event brought together an influential audience of industry leaders, diplomats, members of parliament, former ministers, consular officials, senior legal figures, and media executives, all eager to hear from Mr Sinodinos, who now serves as Partner and Chair of The Asia Group’s Australia Practice in Washington D.C.


His presentation drew on decades of experience in public service and diplomacy, including his time representing Australia during the Trump and early Biden administrations.
Opening remarks were delivered by Paul Nicolaou, Executive Director of Business Sydney, who acknowledged a number of dignitaries in attendance with his trademark energy and warmth.
Bill Kritharas, Partner at Sparke Helmore, formally welcomed Mr Sinodinos and reflected on his distinguished career and long-standing contribution to public life.



In his keynote address, Mr Sinodinos explored a range of global trends shaping international policy and security in the 21st century.
While acknowledging the complexity of current global affairs, he emphasised the need for nations like Australia to remain clear-eyed and resilient in navigating an increasingly multipolar world.
Key themes included:
- The rise of misinformation and deepfake technologies, and the importance of remaining vigilant and informed in an age of digital disruption;
- The evolving nature of international partnerships, with a focus on strengthening Australia’s resilience amid broader uncertainty in global leadership;
- The importance of critical minerals, trade policy and industrial cooperation in securing national and regional interests;
- The increased role of technology in modern diplomacy and defence, as countries adapt to shifting geopolitical and digital landscapes;
- A recognition that traditional alliances may require new levels of strategic engagement, with emphasis on shared interest and mutual benefit;
- And the need to build national self-sufficiency and institutional trust in a time of rapid political and economic transformation.


A thought-provoking Q&A session was facilitated by Helen Liossis CPA GAICD JP, a respected governance professional and non-executive director with a distinguished career across public sector leadership, infrastructure, and corporate strategy.
Liossis guided the discussion with poise and insight, drawing out broad questions around defence policy, regional engagement, and Australia’s positioning amid shifting global power structures.
Attendees appreciated Mr Sinodinos’ sharp analysis and measured reflections, informed by his time both in diplomacy and the private sector.



Notable guests included NSW Minister for Industrial Relations, Sophie Cotsis MP, NSW Shadow Minister for Health, Kellie Sloane MP, Deputy Chief Magistrate Theo Tsavdaridis, Consul General of Greece in Sydney Ioannis Mallikourtis, other consular representatives, business leaders, and multicultural media.
The event concluded over lunch, offering guests the opportunity to engage further in informal discussion and networking. It was a timely and valuable occasion to consider the global forces shaping Australia’s future, and to hear from one of the country’s most seasoned political and diplomatic figures.
