Marriage is a major commitment that brings together not only two people but often families, finances, and long-term plans. Yet, not all marriages last a lifetime.
Many people ask what percentage of marriages end in divorce because they want to understand how common divorce actually is. The trouble is, a lot of what circulates online is outdated or simply wrong, and one figure in particular, the claim that half of all marriages end in divorce, gets repeated so often that most people accept it without question.
By looking at the most current statistics, patterns, and reasons behind divorce in Australia, we can give you a clearer, more accurate picture of why some relationships end and what couples can do to protect themselves.
Is It True That Half of All Marriages End in Divorce?
No. This is one of the most persistent myths in relationship statistics, and it’s never actually been accurate, not in Australia, and not even in the United States, where the figure originally came from.
The “50%” claim traces back to a rough projection made in the US during the 1970s and 80s: if divorce trends at the time continued indefinitely, roughly half of marriages might eventually end in divorce. That was an extrapolation, a guess about the future based on short-term patterns, not a figure based on actually following real couples over time. It was never an accurate description of Australia, and it stopped being an accurate description of the US decades ago too.
In Australia, the real figure has consistently sat well below that mark. Based on long-term cohort analysis from the Australian Bureau of Statistics, around 28% of marriages entered into in 1985 to 1987 were projected to end in divorce, rising to about 33% for marriages entered into in 2000 to 2002. Current estimates for more recent marriages generally sit in a similar range, closer to one in three than one in two.
What Percentage of Marriages End in Divorce in Australia Today?
Australia’s divorce rate has been gradually declining for years. According to the latest data released by the Australian Bureau of Statistics, covering 2024 (the most recent year available), there were 47,216 divorces granted in Australia, with a crude divorce rate of 2.1 divorces for every 1,000 people aged 16 and over. This continues one of the lowest sustained divorce rates recorded since the introduction of no-fault divorce in 1975.
When people ask what percentage of marriages end in divorce, there’s no single, perfectly precise number, since divorces can happen many years after a marriage begins, and today’s newlyweds won’t have a final answer for decades. But based on the cohort data above, the best current estimate remains that roughly one in three Australian marriages eventually ends in divorce, not one in two.
It’s also worth understanding what’s not captured in these figures. Fewer Australians are marrying compared to previous generations, with the marriage rate falling from around 9.3 per 1,000 people in 1976 to about 5.5 per 1,000 in 2024, and many couples now choose long-term de facto relationships instead of marriage. These relationships aren’t included in divorce statistics, so the official numbers only reflect legal marriages that ended through the courts, not the full picture of Australian relationship breakdowns.
At What Stage of Marriage Do Most Divorces Occur in Australia?
Statistics show that the median duration of marriage before divorce is now about 13.2 years, according to the latest 2024 figures, a slight increase on previous years. Many separations happen within the first decade, often due to pressures around finances, parenting, and adjusting to shared responsibilities.
This means that when people ask what percentage of marriages end in divorce, much of the answer lies in the early to middle years of married life. The median age at divorce has also risen alongside this, now sitting at around 47.1 years for men and 44.1 years for women.
Although some marriages end after 20 or more years, most divorces still take place before that milestone. The pattern highlights the importance of the first stages of marriage, when couples face many major changes at once.
How Does Australia’s Divorce Rate Compare Internationally?
Australia isn’t unusual in seeing a decline. Globally, research compiled by Our World in Data shows divorce rates rose sharply across many developed countries between the 1970s and 1990s, before plateauing or falling in a number of them since, including the UK, where the share of marriages ending in divorce within the first five years has roughly halved since its 1990s peak.
Australia’s own divorce rate compared with the United States shows a similar pattern, with Australia generally maintaining a lower rate than the US across recent decades. As in Australia, much of this global shift is linked to people marrying later, more cohabitation before marriage, and changing social attitudes toward both marriage and divorce.
How Do Age and Timing Impact Divorce Percentages in Australia?
The age at which people get married can affect the risk of divorce. Couples who marry very young generally have a higher chance of separating, while those who marry later, now a median of 32.8 years for men and 31.2 years for women in 2024, tend to have more stable relationships. This helps explain what percentage of marriages end in divorce in different groups.
The timing of life events also matters. Major changes such as the birth of children, buying a home, or career pressures can place strain on a relationship.
Couples who manage these challenges with strong communication may be less likely to divorce, while those who struggle may contribute to higher divorce figures.

What Social or Financial Factors Influence Divorce Percentages?
When we look at what percentage of marriages end in divorce, social and financial pressures remain major influences. Money issues are one of the most common sources of conflict between couples. Disagreements about spending, saving, or debt can slowly damage trust in a relationship.
Social expectations also shape divorce patterns. Shifts in gender roles, career goals, and parenting responsibilities can create tension if couples cannot agree on how to share the load.
Other pressures, such as mental health struggles, substance abuse, and family conflict, can also increase the chance of separation. Rising living costs have also led some couples to delay formal divorce and property settlement for financial reasons, even where the relationship has already broken down, sometimes remaining separated while still living under the same roof for a period.
Australia’s culture has become more accepting of divorce over time, which means couples may feel less social pressure to stay in unhappy marriages. While this greater acceptance supports personal freedom, it also affects how divorces are recorded and interpreted over time.

How Can Couples Protect Themselves if Divorce Becomes Likely?
Understanding what percentage of marriages end in divorce, and how much of the “50%” narrative is myth rather than fact, can help couples prepare with realistic expectations rather than fear. Protecting a relationship isn’t always about avoiding divorce at all costs, but about making informed decisions. Open communication, financial planning, and counselling are tools that can strengthen a marriage.
If separation does occur, seeking legal guidance can help couples understand their rights and responsibilities. Our guide on the key stages of the divorce process in Australia walks through what to expect from application through to a finalised divorce order. Family lawyers in Australia assist with issues such as property division, parenting arrangements, and financial settlements.
Early advice can make the process clearer and help ensure that both parties, and their children, are considered fairly.
Moving Forward With Confidence
Asking what percentage of marriages end in divorce is more than looking for statistics. It’s about understanding the patterns behind relationships and learning what factors make some marriages stronger than others.
While data shows that roughly one in three marriages does end in divorce, not one in two, it also shows that most marriages last, and that the trend in Australia has been moving toward greater stability, not less, for several decades now. With the right support and preparation, couples can feel more confident about the future, no matter what it holds.

FAQs
What percentage of married couples get divorced in Australia?
While statistics fluctuate year to year, roughly 30% of marriages in Australia ultimately end in divorce. According to data from the Australian Bureau of Statistics (ABS), the annual crude divorce rate sits at approximately 2.1 divorces per 1,000 people.
Is divorce 50/50 in Australia?
No. There is a common misconception that property and assets are automatically divided 50/50 after a separation. Under the Family Law Act 1975, Australian courts do not apply a 50/50 starting point. Instead, they evaluate each case individually using a four-step process to achieve an outcome that is legally “just and equitable” based on contributions and future needs.
What is a 70/30 split divorce in Australia?
A 70/30 split refers to an uneven property settlement where one party receives 70% of the total asset pool and the other receives 30%. This type of significant division is relatively rare and is not a standard formula. It only occurs in specific circumstances where a court or agreement deems it necessary—such as when there is a massive disparity in future earning capacities, long-term health needs, or primary care responsibilities for young children.
What is the most common reason for divorce in Australia?
Australia operates under a “no-fault” divorce system, meaning the court only requires proof that the marriage has broken down irretrievably (with a 12-month separation period) rather than looking at why it ended. However, family law practitioners report that the underlying drivers leading to separation typically include poor communication, financial stress, constant conflict, infidelity, and domestic or emotional abuse.
