Gambling addiction: the signs, why it happens and the help that works

What gambling addiction is

Gambling addiction is when you cannot stop gambling even though it is causing you harm. That is the definition used by healthdirect, the government-funded health advice service, and it is the same condition clinicians call gambling disorder or pathological gambling.

The line is harm, not how often you bet. Most people who gamble never develop a problem. It becomes one when gambling starts to damage your finances, relationships, work or health, and you keep going anyway.

It is not a character flaw. healthdirect describes gambling as a form of addiction that changes brain chemistry in ways similar to alcohol or drug addiction. That is why willpower alone often is not enough, and why proper treatment exists.

Signs of gambling addiction

The signs below come from healthdirect's self-check. You do not need all of them for gambling to be hurting you.

People close to you may notice different things first: frequent borrowing, unpaid bills, more arguments and changes in mood. If several of these sound familiar, that is a good reason to talk to a counsellor, even if you are not sure you would call it an addiction.

How the PGSI score works

The self-assessment on Gambling Help Online uses the Problem Gambling Severity Index (PGSI), the same tool Australian researchers use. Your answers add up to a score from 0 to 27, which falls into one of four bands.

The bands are the ones the Australian Gambling Research Centre reports. A score is a starting point for a conversation, not a diagnosis. Only a health professional can diagnose gambling disorder.

How common gambling harm is in Australia

Gambling harm is common, and you are far from alone. The Australian Gambling Research Centre surveyed 3,881 adults between August and October 2024 for its national pilot study.

The study's weighted population was 20,879,708 adults, so 2.6% works out to roughly 540,000 people in the high-risk group, in our calculation. The AIHW also reports that 6.0% of adults said they had been harmed by another person's gambling, mostly a family member, friend or colleague.

Why gambling becomes addictive

There is rarely one cause. healthdirect points to several factors that combine:

• Escape. Some people start gambling heavily to get away from other difficulties, such as stress, grief or isolation.
• Brain chemistry. As above, the changes are similar to those seen with alcohol and other drugs, which is why stopping can feel so hard.
• Product design. healthdirect notes that gambling products are often designed to make you feel like you are winning when you are not.
• Culture. Gambling is widely accepted in Australia and treated as a normal part of social life.

The maths is part of the picture too. GambleAware NSW says poker machines return 85% to 92% of all money bet over their lifetime, so a machine keeps 8 to 15 cents of every dollar put through it on average, however a session feels. Our guide to how pokies work explains why wins and losses are random from one spin to the next.

Treatment and help that works

Gambling addiction responds to treatment, and most options cost nothing.

CBT helps you spot the thoughts that drive gambling and build ways to handle urges and triggers. Motivational interviewing helps you work out what you want to change and why. Our gambling addiction counselling guide lists the free services in each state and what a session involves.

Cutting off access while you get help

Treatment works better when gambling is harder to reach. BetStop, venue exclusion, bank blocks and blocking software each close a different door, and our self-exclusion guide explains what each one covers. For a step-by-step plan covering money, urges and slips, see how to stop gambling.

Pundit tip: you do not have to be sure you are addicted before you call. Counsellors talk to plenty of people who are simply worried, and an early call is easier than a late one.

If you are in crisis

If gambling has left you feeling hopeless or thinking about harming yourself, call Lifeline on 13 11 14 or text 0477 13 11 14, any time. If you or someone else is in immediate danger, call 000.
