Sustainable Winegrowing Australia is excited to announce the appointment of Siobhan Toohill as the independent Chair, marking an important milestone in the program’s governance evolution and future strategic direction.
The appointment is the first step in the implementation of governance reforms announced in December 2025, which established the transition to an independent Chair, skills-based Board and dedicated Executive Officer to strengthen oversight, responsiveness and long-term impact across the Australian grape and wine sector.
Ms Toohill brings extensive executive leadership experience in sustainability strategy and risk management and involvement in shaping industry frameworks and tools across climate, nature and social impact. As Chair, she will play a central role in guiding Sustainable Winegrowing Australia through its next phase of development — including oversight of Board and Executive Officer selection, governance establishment, and development of the program’s strategic plan.
Her leadership will support the program’s continued growth, balancing this with the need to remain practical and cost effective, credible and internationally recognised while delivering value to Australian grapegrowers and winemakers.
Sustainable Winegrowing Australia is a national collaboration between Australian Grape & Wine, Wine Australia and the Australian Wine Research Institute (AWRI), providing a framework for continuous improvement, benchmarking and certification across environmental, social and governance practices.
The establishment of an independent Chair and refreshed governance model reflects the sector’s shared commitment to strengthening sustainability performance and ensuring the program is equipped to meet evolving market, climate and regulatory expectations.
“Siobhan’s appointment as independent Chair represents a significant step forward for Sustainable Winegrowing Australia. Her expertise in sustainability leadership and system transformation will be invaluable as the program enters this next phase of governance maturity and strategic impact.” Lee McLean, Chief Executive Officer, Australian Grape & Wine Inc.
“Siobhan’s appointment confirms the sector’s commitment to strong, independent governance and credible sustainability leadership. Sustainable Winegrowing Australia and its members will benefit from her knowledge and guidance across climate, nature and social impact.” Dr Mark Krstic, Managing Director, AWRI.
“This is an important milestone in the evolution of Sustainable Winegrowing Australia. Siobhan’s strategic and governance experience will ensure the program is positioned for long-term impact and aligns with the expectations of members, regulators and the broader community.” Dr Martin Cole, Chief Executive Officer, Wine Australia.
“I’m delighted to take on the role of Chair for Sustainable Winegrowing Australia. The program plays a critical role in supporting the sector’s sustainability ambitions, and I look forward to working with industry to strengthen its impact, accessibility and global credibility.” Siobhan Toohill, Chair, Sustainable Winegrowing Australia.
Ms Toohill’s appointment comes at a time of strong program momentum, with growing national participation and sustained focus on continuous improvement, usability and cost-effectiveness for members.
Ms Toohill is working closely with the Australian Grape and Wine, AWRI and Wine Australia to finalise the appointment of the Sustainable Winegrowing Australia Advisory Board and recruitment has commenced for an Executive Officer for the program.
