Trauma therapy in Australia: understanding EMDR, CBT, and what to expect

Something happened. Maybe years ago, maybe more recently. And it's still affecting you in ways that don't quite make sense. You've researched trauma therapy and found yourself looking at acronyms that mean very little: EMDR, CBT, TF-CBT, prolonged exposure. You want to understand what actually works, what each one involves, and how to choose. That's a reasonable thing to want before you book.

The quick answer: EMDR vs CBT for trauma

Both EMDR (Eye Movement Desensitisation and Reprocessing) and trauma-focused CBT (Cognitive Behavioural Therapy) are recognised first-line treatments for PTSD and other trauma-related conditions, with strong evidence in Australian and international clinical guidelines. They work differently. CBT typically involves talking through the traumatic memory, identifying and shifting trauma-related thoughts, and gradually reducing avoidance. EMDR uses bilateral stimulation (eye movements, taps, or sounds) while you briefly recall the memory, helping the brain reprocess it so it loses its emotional charge. Both approaches have strong evidence. The right choice depends on your trauma history, what you're comfortable with, and your therapist's training. A good clinician will discuss both with you before recommending an approach.

Why trauma therapy looks different to other therapy

Trauma fundamentally changes how the nervous system processes safety, threat, and memory. The events that caused harm get stored in the body and brain in a way that keeps them feeling current rather than past. That's why people experiencing PTSD or complex trauma find that talking about what happened in ordinary therapy doesn't always help. Sometimes it makes things worse, because revisiting the memory without specific trauma-informed structure can re-activate the trauma response without resolving it.

Trauma-focused therapies were developed precisely because of this. They contain structured protocols for engaging with traumatic material safely, in ways that allow the brain and body to process and integrate the experience rather than re-live it.

What is CBT for trauma?

Trauma-focused CBT is one of the most studied treatments for trauma, and Australia's PTSD guidelines strongly recommend it for adults, children and teenagers (Phoenix Australia, 2020).

What happens in trauma-focused CBT

TF-CBT typically involves between 8 and 16 sessions and includes several core components:

• Psychoeducation: understanding what trauma is, how PTSD works, and why your brain and body have responded the way they have
• Stabilisation skills: learning techniques to regulate your nervous system, manage flashbacks, and stay grounded
• Cognitive restructuring: identifying and challenging trauma-related beliefs ("it was my fault", "the world isn't safe", "I should have done something different")
• Exposure work: gradually and safely engaging with the traumatic memory, often by writing or speaking the story in detail in session, until the memory loses its overwhelming charge
• In vivo exposure: gradually re-engaging with situations, places, or activities that have been avoided since the trauma

The exposure components can sound daunting. Exposure work is carefully paced and only starts once stabilisation skills are in place.

What is EMDR?

EMDR stands for Eye Movement Desensitisation and Reprocessing. It was developed in the late 1980s and has since accumulated robust research evidence supporting its effectiveness for PTSD. It's also a first-line recommended treatment in major international guidelines.

What happens in EMDR

EMDR follows an eight-phase protocol:

• History taking and treatment planning: identifying the memories and experiences that need targeting
• Preparation: building stabilisation resources and explaining the process
• Assessment: identifying the specific image, beliefs, emotions, and body sensations linked to the target memory
• Desensitisation: this is where the bilateral stimulation happens. While briefly recalling aspects of the memory, you follow the therapist's hand or use tappers/audio that alternates left and right. This appears to allow the brain to reprocess the memory in a different way
• Installation: strengthening a more adaptive belief related to the memory
• Body scan: checking that physical tension related to the memory has resolved
• Closure: ensuring you leave each session in a regulated state
• Re-evaluation: checking progress in subsequent sessions

For single-incident trauma, EMDR can sometimes work in a relatively small number of sessions. For complex or developmental trauma, it usually takes longer and is sometimes combined with other approaches.

How to choose between EMDR and CBT

Both have strong evidence. Some factors that may influence which is right for you:

• EMDR tends to suit people who don't want to talk through traumatic memories in detail. The processing happens internally rather than verbally, and many people find this less daunting.
• TF-CBT tends to suit people who want a structured, skills-based approach with clear homework, and who feel comfortable verbalising what happened.
• Complex trauma (multiple traumas, childhood-onset, attachment-related) often benefits from a longer, integrated approach that may combine elements of both, plus additional stabilisation work.
• Single-incident trauma in adults often responds well to either, sometimes in relatively few sessions.
• Therapist training matters. EMDR requires specific accredited training. Not every psychologist offers it. Trauma-focused CBT is more widely practised but also requires specific training to deliver well.

The honest answer is that the best therapy for you is often the one delivered by a therapist you trust who is properly trained in the modality. That matters more than the specific letters of the approach.

How long does trauma therapy take?

The number of sessions varies. PTSD related to a single incident in adulthood often needs fewer sessions. For complex trauma, particularly trauma rooted in childhood or repeated experiences, treatment is usually longer, sometimes 30 sessions or more, and progresses through stages. There's no fixed timeline. Your psychologist will give you a realistic estimate after a thorough assessment.

Medicare and trauma therapy

Both EMDR and CBT are funded under Medicare's Better Access scheme when provided by a registered or clinical psychologist with a GP Mental Health Treatment Plan. You can claim partial rebates for up to ten sessions per calendar year. Medicare doesn't differentiate between specific therapy modalities, only between the type of clinician providing them. For complex trauma requiring more sessions, options include private health insurance, self-funding, or accessing additional sessions through specific funding pathways such as victims' services schemes.

How we approach this at Unbound Minds

Trauma therapy isn't a one-size-fits-all proposition. The work always starts with a thorough assessment, because the most important question isn't "which modality should we use" but "what kind of trauma is this, what's your current capacity, and what does safe progress look like for you specifically?"

Our trauma work follows a phased approach. First, stabilisation, building the resources you need to engage with traumatic material without becoming dysregulated. Second, processing, using EMDR, trauma-focused CBT, or an integrated approach depending on the picture. Third, integration, helping you rebuild relationships, identity, and meaning after the trauma's grip has loosened.

The preparation phase matters, and we don't rush it. Trying to process trauma before someone has the capacity to do so is unhelpful at best and harmful at worst.

If you're not sure whether what you're experiencing is trauma or something else (such as anxiety, depression, or burnout), our pieces on related topics can help. The difference between psychologists and psychiatrists explains who treats what, and our piece on how to find a good psychologist near you walks through the practical steps of starting.

When to seek trauma therapy

Some indicators that trauma therapy may help:

• Intrusive memories, flashbacks, or nightmares about a past event
• Avoidance of places, people, or activities connected to a past experience
• Hypervigilance, exaggerated startle response, or constant feeling of being on edge
• Numbness or disconnection from your emotions or your body
• Persistent guilt, shame, or self-blame related to a past experience
• Symptoms that have lasted more than a month after a traumatic event
• A sense that something happened to you that's still shaping your current life

You don't need a formal PTSD diagnosis to benefit from trauma-informed therapy. Many people experience significant trauma responses without meeting full diagnostic criteria, and they still deserve support.

We see clients at our two clinics, Kingswood (Nepean Health Hub) and Gledswood Hills (Gregory Hills Health and Business Centre), and by telehealth across NSW. People come to us from St Marys, Glenmore Park, Emu Plains, Cranebrook and nearby suburbs. You can find more on our trauma and PTSD treatment page.

Frequently asked questions

What is the difference between EMDR and CBT for trauma?

CBT works through structured talking, gradually engaging with the traumatic memory and shifting trauma-related thoughts and behaviours. EMDR uses bilateral stimulation (eye movements, taps, or sounds) while briefly recalling the memory, which appears to help the brain reprocess it so it loses its emotional charge. Both have strong evidence and both are recommended in international clinical guidelines.

How many sessions of EMDR do you need?

For single-incident trauma in adults, EMDR can sometimes resolve the core memory in a relatively small number of sessions, though preparation and integration usually require more. For complex or developmental trauma, treatment generally takes longer, often spanning many months or longer, and is delivered in phases.

Is EMDR better than CBT for PTSD?

Neither has consistently outperformed the other in head-to-head studies. Both are recommended as first-line treatments for PTSD. The right choice depends on the type of trauma, personal preference, what you find most tolerable, and your therapist's specific training.

What happens in a trauma therapy session?

Sessions vary by approach but generally include checking in on how you've been since last session, doing a piece of trauma-focused work (which may involve discussing the memory, doing EMDR processing, or skill practice), and ensuring you leave the session in a regulated state. Stabilisation and grounding skills are emphasised early.

Does Medicare cover EMDR therapy?

Yes. EMDR is funded under Medicare's Better Access scheme when delivered by a registered or clinical psychologist with a GP Mental Health Treatment Plan. Medicare doesn't specify which therapy modality is used, only the type of clinician providing it. You can claim partial rebates for up to ten sessions per calendar year.

How do I know if I need trauma therapy?

If you're experiencing intrusive memories, flashbacks, persistent avoidance, hypervigilance, numbness, or a sense that a past experience is still shaping your current life, trauma therapy may help. You don't need a formal PTSD diagnosis. A psychologist can assess what's going on and recommend the right approach.
