No one enters a marriage thinking it will end, yet for many Australian couples, divorce becomes an unavoidable part of life. According to the Australian Institute of Family Studies, nearly one in three marriages ends in divorce. The Australian Bureau of Statistics also reports that over 56,000 divorces were granted in a single year, showing just how common marriage breakdowns are.
Understanding the reasons for divorce can help couples tackle problems early, strengthen their bond, and avoid the financial and mental health strain that often comes with separation.
This guide to the top 12 reasons why marriages fail in Australia sheds light on the most common causes and offers insights on how to build lasting, healthy relationships. Let’s get into it.

What Are the Common Reasons for Divorce in Australia?
Every marriage has its share of challenges, but certain patterns keep showing up when relationships fall apart.
In Australia, these issues are shaped by social norms around independence and equality, cultural expectations of family life, and the country’s no-fault divorce system, which has been in place since the Family Law Act 1975. This law is a key reason why divorce is so accessible in Australia, as it allows couples to separate without having to prove blame.
Understanding why so many Australian marriages end can help couples see the warning signs early and give them a chance to work through their issues. Here’s a closer look at the 12 most common reasons for divorce in Australia and how they play out in real life.
1. Infidelity and Cheating
Infidelity is one of the most painful reasons for a marriage breakdown. In Australia, where trust and honesty are highly valued, an affair can shatter the foundation of a relationship.
The emotional fallout is often intense, anger, sadness, and deep confusion can overwhelm both partners.
The no-fault divorce system in Australia means couples don’t need to prove blame, but the betrayal of an affair often makes it impossible to stay together. Rebuilding trust after cheating is incredibly difficult, and for many couples, the relationship never fully recovers.
Statistics from the Australian Institute of Family Studies show that infidelity is a key factor in nearly 20% of divorces. This betrayal doesn’t just end marriages. It leaves a lasting mark on everyone involved.
2. Lack of Communication
Good communication is the foundation of a healthy marriage. In Australia, where open conversation is valued, poor communication can break even the strongest bonds.
Small issues that aren’t talked about can snowball into constant arguments or complete silence. Common communication problems include not listening, dismissing feelings, or shutting down altogether.
When couples stop sharing their thoughts and feelings, the connection fades. Without open communication, the relationship can slowly fall apart, often ending in divorce.
3. Financial Problems
Money troubles are one of the most common reasons for marital breakdown in Australia.
Financial stress can turn even small disagreements into major conflicts. Disagreements over spending, saving, and managing debt can create constant tension between partners.
For some couples, different views on money or hidden debts become impossible to work through. Rising living costs and job insecurity only add to the pressure.
Examples of financial stress leading to divorce include one partner overspending while the other wants to save or sudden job losses that make it hard to pay the bills. Financial issues are often at the heart of divorce applications in the Family Court of Australia as couples struggle to find a way forward.
4. Domestic Violence and Abuse
Domestic violence and abuse can destroy a marriage from the inside out. In Australia, this abuse can take many forms: emotional, physical, sexual, and even financial.
These actions create a climate of fear, not love.
Emotional abuse can involve constant criticism, manipulation, or controlling behaviour. Physical abuse includes hitting, pushing, or other violent acts.
Financial abuse often involves controlling a partner’s money to limit their freedom, while sexual abuse violates personal boundaries and autonomy. These forms of abuse break down trust and safety, making it impossible for a marriage to survive.
Under Australian law, including the Family Law Act 1975, family violence is taken seriously. Many people find that leaving an abusive marriage is the only way to protect themselves and their children.
Leaving an abusive marriage can be a difficult step, but it’s often the only way to ensure safety.
5. Drug and Alcohol Addiction
Drug and alcohol addiction can tear apart even the strongest relationships. Substance abuse often leads to broken promises, financial hardship, and family violence, all of which are major triggers for divorce in Australia.
In fact, substance abuse is recognised by Australian family law as a serious issue that can undermine the well-being of a spouse or children. Around 3.4% of Australians report problematic drug use, while about 20% drink alcohol at risky levels (AIHW).
These patterns can quickly destabilise marriages, turning everyday life into a cycle of stress and conflict.
For many couples, the only way to protect themselves and their children from the chaos of addiction is to separate and seek a divorce through the Family Court of Australia.
6. Incompatibility and Growing Apart
Sometimes, people change and grow in ways they didn’t expect. In Australia, where personal growth and independence are highly valued, these changes can slowly pull couples apart.
Differences in career paths, hobbies, parenting styles, or even simple daily routines can create emotional distance. When two people no longer share the same dreams or values, living together can feel lonely and unfulfilling.
This slow drift apart is a common reason for divorce in Australia. Many couples find that, over time, they have less and less in common.
Ultimately, they realise they’re living separate lives under one roof, and divorce becomes the only way forward.

7. Unrealistic Expectations
Unrealistic expectations can quietly erode even the strongest marriage. Many couples enter marriage with dreams of constant happiness, easy solutions, and a perfect life. But real life rarely matches those expectations.
In Australia, the idea that marriage should always be effortless or conflict-free can lead to deep disappointment. When partners feel let down, resentment and distance grow.
Over time, these unmet expectations become a major factor in divorce, as couples realise their dreams don’t match reality.
8. Lack of Intimacy
A healthy marriage depends on both physical and emotional closeness. In Australia, the pressure of busy lives often means couples neglect their connection.
When partners stop being affectionate or lose that sense of closeness, it can lead to a slow drift apart. Lack of intimacy is often a silent but powerful reason for separation.
9. Mental Health Issues
Mental health challenges like depression, anxiety, and other conditions can weigh heavily on a marriage. Untreated, these issues can create distance, frustration, and sadness, making daily life feel overwhelming.
In Australia, one in five adults will experience a mental health condition in any given year, according to the Australian Institute of Health and Welfare (AIHW). These struggles can make it hard for couples to maintain a supportive, fulfilling relationship.
For many couples, mental health issues contribute to a breakdown in communication and intimacy, leading to emotional distance and, eventually, divorce. Recognising these challenges and getting help early can make all the difference.
10. Family Pressure and Interference
Family pressure and interference can add strain to any marriage. In Australia, close-knit families often expect couples to live up to certain roles or cultural traditions.
When in-laws or family members impose their opinions, it can create tension and resentment. Cultural expectations, like gender roles or family obligations, can clash with what couples want for themselves.
Over time, these conflicts can pull partners in different directions, making it hard to stay united and causing marriages to break down.
11. Work-Life Balance Struggles
Work-life balance can make or break a marriage. In Australia, long work hours, busy schedules, and financial pressures can leave little time for nurturing a relationship.
When work commitments take over, partners may feel like they’re last on each other’s priority list. This neglect can erode closeness and create feelings of resentment.
Over time, poor time management and constant stress can push couples further apart, leading to emotional distance and divorce.
12. Cultural and Religious Differences
Australia’s rich cultural diversity can be both a blessing and a challenge in marriages. Couples from different backgrounds often face difficulties balancing family traditions, religious beliefs, and shared values.
Indigenous Australians and multicultural families may also experience unique pressures and cultural expectations that can strain their relationships. Studies and community reports have shown that cultural and religious differences are a common factor in many divorces, even though exact figures are hard to track.
When couples find it hard to find common ground, these cultural and religious clashes can create emotional distance and conflict. For many, divorce becomes the only path forward when values and beliefs can’t be reconciled.

Frequently Asked Questions (FAQs)
What are the 14 grounds for divorce in Australia?
The “14 grounds for divorce” were part of Australia’s old divorce law, but they were scrapped in 1975. Today, there’s only one ground for divorce:
Irretrievable breakdown of the marriage, shown by 12 months of separation.
Issues like abuse, drug use, or alcohol problems can be relevant in family court matters (like custody or property), but they’re not legally required for a divorce in Australia anymore.
What is the most common reason for divorce in Australia?
The most common reason for divorce in Australia is poor communication skills leading to a relationship breakdown. Other key reasons include financial matters, instances of infidelity, and conflict resolution failures that create psychological harm or a lack of trust.
When you know it’s time to divorce?
You might know it’s time to file an application for divorce if there’s a complete breakdown in communication, repeated aggressive behaviour, or no chance of rebuilding a meaningful relationship.
Seeking marriage counselling or professional advice can help confirm this decision, especially if there’s a pattern of social behaviour problems or affective issues.
What is a 70/30 split divorce in Australia?
A 70/30 split divorce usually refers to the division of assets and marital assets in a financial settlement, where one partner receives 70% and the other 30% of the combined asset wealth. The Family Law Court looks at proper arrangements for child care and financial matters before approving these special circumstances.
What is the #1 reason marriages fail?
Poor communication and lack of active listening are the top reasons marriages fail. Other major factors include instances of infidelity, abusive behaviour, and adjustments to divorce that strain a marriage certificate’s promise of lifelong support.
