Depression
Depression is one of the most common mental health conditions in Australia, affecting an estimated 1 in 7 people at some point in their life. It's more than ordinary sadness — it's a persistent state that affects how you think, feel, and function, and it can make even small tasks feel overwhelming.
Depression is highly treatable. With the right support, most people see meaningful improvement. This page covers what depression looks like, what tends to cause it, and how treatment works.
Recognising it
What are the symptoms of depression?
Emotional & cognitive
- Persistent low mood or feeling "empty"
- Loss of interest in activities you used to enjoy
- Feelings of worthlessness, guilt, or hopelessness
- Difficulty concentrating or making decisions
- Irritability or restlessness
- Recurring thoughts of death or suicide
Physical & behavioural
- Changes in appetite or weight
- Sleeping too much or too little
- Fatigue, even after rest
- Slowed speech or movement, or restlessness
- Withdrawing from friends, family, or usual activities
Not everyone experiences all of these, and intensity varies. Some people also experience unexplained aches, digestive issues, or headaches without immediately connecting them to their mental health.
Understanding why
What causes depression?
There's rarely a single cause — it tends to develop from a combination of factors.
- Biological
- Genetics, brain chemistry, and hormonal changes can all play a role.
- Life circumstances
- Grief, relationship breakdown, financial stress, job loss, or chronic illness.
- Psychological
- Long-standing patterns of negative thinking, low self-esteem, or unresolved trauma.
- Social
- Isolation, lack of support, or ongoing conflict.
- Other conditions
- Depression frequently co-occurs with anxiety, chronic pain, and other health conditions.

Common questions
Frequently asked questions
Is depression the same as feeling sad?
No. Sadness is a normal, temporary response to a specific situation. Depression is a persistent state that affects mood, thinking, and functioning over an extended period, and usually doesn’t resolve on its own the way sadness typically does.
Can depression go away without treatment?
Some mild, situational low moods can improve on their own with time and support. Clinical depression, however, often persists or worsens without treatment. Most people see meaningful improvement with the right therapeutic support.
How long does treatment for depression take?
This varies widely. Some people notice improvement within a few sessions, while others benefit from ongoing support over several months. Your psychologist will work with you to set a plan that fits your situation.
Do I need a GP referral to see a psychologist for depression?
No — you can see a psychologist directly. A GP referral is only required if you want to access a Medicare rebate through a Mental Health Care Plan.
What's the difference between a psychologist and a psychiatrist for depression?
Psychologists provide talk therapy and cannot prescribe medication. Psychiatrists are medical doctors who can prescribe medication and may also provide therapy. Many people see a psychologist for therapy and, where needed, a GP or psychiatrist for medication.
Is online therapy effective for depression?
Telehealth psychology sessions have been found to be effective for many people with depression, offering more flexibility and access, particularly for those in regional areas.
