The Australian Relationship Stress Index (2025)
Where Love Is Breaking — And Where It’s Holding — Across the Country
Relationships are not breaking down the same way in Sydney as they are in Perth, Brisbane, Gold Coast, Adelaide, or Darwin.
Each city produces a different psychological, financial, lifestyle and cultural pressure.
This Index is the first national analysis of:
- Housing affordability stress
- Career load vs emotional labour
- Income volatility
- De facto vs marriage trends
- FIFO/remote work
- Generational wealth expectations
- Migration + mobility patterns
- Household financial imbalance
and how these pressures affect relationship stability.
The result is a national ranking of relationship stress — a powerful tool for couples to understand not only why relationships fail, but where they fail, and what can be done proactively to protect assets and emotional well-being.
The Stress Index Model
Our model measures 7 dimensions:
- Housing Stress – mortgage pressure, rent strain, family deposits
- Income Stability – volatility, seasonal work, job security
- Lifestyle Pressures – social expectations, burnout, culture
- Mobility & Transience – moving, relocation, relationship churn
- Family Influence – intergenerational wealth pressure
- Emotional Labour Load – invisible work imbalance
- Structural Relationship Risks – FIFO, defence, blended families, etc.
Each city receives a 0–100 score.
80+ is “High Risk.”
60–79 is “Moderate Risk.”
<60 is “Stable Environment.”

City-by-City Relationship Pressure Profiles
Let’s break down the profiles
Cairns — The Seasonal Instability Zone
Stress Score: 69/100
Cairns couples experience:
- Income fluctuations from tourism
- Periods of unemployment
- FIFO/remote arrangements
- Family property used as deposits or accommodation
- Younger average de facto relationships
Psychological Profile:
Security fears, unpredictability, and role imbalance.
Why do Cairns couples break up:
One partner becomes the “stable one,” while the other struggles financially, leading to resentment.
BFA protection:
Perfect for documenting contributions, protecting family property, and managing seasonally unstable income.
Adelaide — The Intergenerational Pressure Belt

Adelaide couples often deal with:

Canberra — The Structured Stability Trap
Stress Score: 58/100
Canberra couples often appear stable because of:

What Causes High Separation Risk Across Australia?
Patterns across all cities show the same drivers:
🔹 1. Financial Pressure
The #1 predictor of separation.
🔹 2. Unbalanced Emotional Labour
Invisible mental load destroys relationships quietly.
🔹 3. Mobility + Transient Lifestyles
Relationships need stability.
🔹 4. Unequal Contributions
Both financial and emotional.
🔹 5. Family Intervention
Parents contributing to deposits → MASSIVE later disputes.
🔹 6. Property Market Stress
Boom cities = boom separations.
