Strategy and Governance Experience

"My career has included roles at two global consultancy firms – first Arup, and now Integral Group – providing strategic advice in the areas of building performance, environmental design and sustainability. I’ve been fortunate to have worked on a diverse range of projects, from single dwellings to large-scale urban renewal, and my work has taken me to Asia, North America, Europe and the Middle East, with a four year stint living in London.


My current role is National Head of Sustainability at Integral Group, providing strategic advice both to external clients and collaborators as well as internally within the organisation at the executive level. I am accountable for the sustainability business unit’s P&L, which involves strategic business planning, management of people distributed across the east coast of Australia, and reporting to the global executive team. I am also responsible for the Australian region’s Sustainability R&D strategy, identifying meaningful initiatives and partnerships, managing interactions with global R&D activities and supporting dissemination of outcomes."

Career history demonstrating experience and insight that you will bring to the leadership of APHA

"I have served as a Board Director for a number of years within my current organisation (Integral Group), and currently hold an executive role as Head of Sustainability. These roles have equipped me with skills and knowledge in governance, strategy development and implementation. 

My approach to these roles focuses on developing a genuine understanding of key objectives, finding alignment amongst disparate views and realising potential through action.
Most recently I have been tasked with developing the operational strategies for the Integral Group Australia regional business, which I have undertaken through a series of facilitated workshops, staff engagement exercises and guided translation of vision to objectives to actions.

Please provide an example to demonstrate your strength as an influential leader that is able to drive change and outcomes? 
"I would describe my style of leadership as ‘people first’, recognising that effective capacity building and empowering changemakers starts with people, rather than technical knowhow. I’ve used this philosophy to re-shape two successful sustainability businesses, developing a united purpose, rethinking our approach to market and enabling diversity in team, projects and clients. 
A recent example of driving change is the development of a Passive House Playbook, which Integral Group were engaged by Development Victoria to create. I adopted a Regenerative approach in facilitating a series of multidisciplinary workshops, focusing on the potential of PH rather than starting from business-as-usual roadblocks. Through this approach, we were able to collaboratively create a pathway to PH at scale that is technically feasible and (just about) cost-neutral.

Why does this opportunity attract you?  "A couple of days ago I heard Clare Parry say that Passive House is powerful because it focuses on aspects we traditionally do terribly but that have tremendous impact when done right. And that resonates with me. Passive House sits at the intersection of many of my interests – wellness, performance, capacity building, physics – so the opportunity to contribute to the success of APHA, and unlock what I see as huge potential in the market, is incredibly enticing."

General Board Member


The building industry accounts for almost 40% of all global carbon emissions worldwide. The buildings we design today will still be operational by 2050. Reaching net zero will require huge changes to our houses, offices, and schools and the way we live in them.
