Introduction: The Population Paradox
Imagine an Australia of tomorrow—how many people will call it home? How will we share resources across our vast continent? What legacy will we leave for future generations? These questions formed the heart of a groundbreaking scientific gathering in 2012, when Australia's brightest early-career researchers converged to tackle one of our nation's most pressing yet neglected issues: shaping a visionary approach to our population future.
"No scientific 'optimal' population size for Australia exists. Instead, our future depends on understanding the intricate interplay between population trends and the values we hold dear as a society." 6
Australia's Population Context: The Numbers Behind the Story
A Nation in Demographic Transition
By December 2012, Australia's population reached 22.9 million people 5 , with distinct regional variations in growth patterns. Western Australia emerged as the nation's growth hotspot, expanding at 3.5% annually 5 —more than double the national average.

The Think Tank Approach: A New Way of Thinking About Population
Breaking Down Silos
The 2012 Theo Murphy High Flyers Think Tank intentionally blended diverse expertise 6 . Economists debated with ecologists, social scientists conversed with technologists, creating emergent insights impossible within narrow disciplinary boundaries.
Interdisciplinary Teams
Small working groups tackled population challenges from different angles
Vigorous Debate
Participants engaged in passionate discussion about wide-ranging possibilities 6
Consensus Building
Foundational principles emerged through collaborative deliberation
Core Values for Population Planning
The Think Tank identified six core values that should guide Australia's population decisions 6 :
Equity
Fair distribution of resources and opportunities across society
Sustainability
Meeting present needs without compromising future generations
Opportunity
Creating conditions for all Australians to flourish
Diversity
Valuing cultural, biological, and experiential variety
Key Recommendations: A Blueprint for Informed Democratic Dialogue
National Conversation
The Think Tank's flagship recommendation was the initiation of a comprehensive national conversation on Australia's population future 6 . This grassroots-oriented approach would use various mechanisms to bring communities together to deliberate on Australia's future.
- Established by universities and researchers
- Open to broad cross-section of communities
- Engaging urban and rural Australia 6
Science in Public Discourse
The Think Tank identified three critical areas where science could enhance population discussions 6 :
Exploring Future Scenarios: The Four Critical Questions
Who Will We Be?
Examining Australia's future identity in terms of age structure, cultural composition, and regional distribution 6
Demographic TransitionHow Will We Share?
Addressing economic and distributive implications of population trends 6
Resource AllocationWhat Will We Do?
Focusing on economic participation, productivity, and work in future Australia 6
Technological TransformationHow Shall We Live?
Addressing environmental dimensions and settlement patterns 6
Ecological SustainabilityThe Scientist's Toolkit: Essential Resources for Population Research
| Tool/Resource | Primary Function | Application in Population Research |
|---|---|---|
| Census Data | Provides comprehensive demographic snapshot | Understanding population composition, distribution, and characteristics 7 |
| Estimated Resident Population (ERP) | Measures population changes between censuses | Tracking quarterly and annual population trends 1 5 |
| Natural Increase Calculations | Tracks births minus deaths | Analyzing demographic transition and fertility patterns 7 |
| Net Overseas Migration Statistics | Measures migration impact on population | Understanding international migration contributions to growth 5 |
| Population Modeling | Projects future demographic scenarios | Informing long-term planning and policy development 6 |
| Cross-disciplinary Frameworks | Integrates multiple perspectives | Addressing complex population challenges holistically 6 |
Conclusion: Toward an Informed Democratic Future
The 2012 Theo Murphy High Flyers Think Tank offered a visionary approach to population questions that remains profoundly relevant today. By rejecting simplistic numerical targets and embracing complexity, diversity, and democratic deliberation, the Think Tank provided a template for how societies might grapple with fundamentally value-laden demographic choices in scientifically informed ways.
"Science has played a remarkably small part in public debates on Australia's future population." 6
Perhaps most importantly, the Think Tank reminds us that population questions are ultimately about what kind of Australia we want to create together. The quality of our demographic future may depend less on how many we are, and more on how wisely we choose to live together.
The values of equity, sustainability, opportunity, diversity, justice, and agency provide a moral compass for Australia's ongoing national conversation about population.
