1. What OCD is and how it is diagnosed
OCD is a clinical condition characterised by two core features. Obsessions and compulsions. Obsessions are recurring, intrusive thoughts, images, or urges that cause significant distress. Compulsions are repetitive behaviours or mental acts performed to reduce that distress or prevent a feared outcome. The DSM-5 classifies OCD as its own diagnostic category, separate from anxiety disorders, reflecting how distinct its presentation and treatment pathway are.
People often use "OCD" loosely to mean being tidy or organised. Clinically, OCD is defined by the degree to which obsessions and compulsions consume time, cause distress, and interfere with daily functioning. A person with OCD is caught in cycles that feel impossible to break without help. OCD affects a significant proportion of the population at some point in life, making it one of the more common conditions a registered psychologist encounters in practice.
OCD does not look the same in every person. Common themes include fears of contamination, fears of causing harm, unwanted sexual or violent intrusive thoughts, symmetry and ordering compulsions, and checking rituals. Some people experience primarily mental compulsions rather than visible behaviours. Accurate identification of the OCD subtype shapes the treatment plan, which is one reason a structured psychological assessment matters before therapy begins.
2. Evidence-based treatments for OCD. ERP and CBT
Exposure and Response Prevention (ERP) is the first-line, gold-standard psychological treatment for OCD. ERP involves gradual, structured exposure to feared situations or thoughts while supporting the person to refrain from carrying out compulsions. Over time, this process reduces the anxiety associated with obsessions and breaks the compulsion cycle. International clinical guidelines recommend ERP as the primary evidence-based intervention for OCD.1
ERP is delivered within a Cognitive Behavioural Therapy (CBT) framework. CBT addresses the thought patterns that maintain OCD cycles, while ERP provides the behavioural component. Together, they form a structured, time-limited approach where sessions follow a deliberate sequence rather than open-ended discussion. The therapy is active. Between-session tasks are a core part of the work, not optional extras.
Acceptance and Commitment Therapy (ACT) is sometimes used alongside ERP, particularly when a person's relationship with intrusive thoughts is a central difficulty. ACT supports the development of psychological flexibility, helping a person relate to distressing thoughts without being controlled by them. Constanza Tirado Subiabre draws on CBT and ERP in her work with OCD, and these are the methods with the most established evidence base for this condition.
3. What "evidence-based" means when you are choosing a psychologist
When a psychologist describes their approach as evidence-based, this means the treatment methods they use have been tested in peer-reviewed clinical trials and shown to produce reliable outcomes for specific conditions. For OCD, this means ERP delivered within a CBT framework, not a general supportive counselling approach. The distinction matters because not all talking therapies are equally effective for OCD.
In practical terms, evidence-based OCD treatment has a recognisable structure. Sessions are not simply conversations about how the week went. A registered psychologist working with OCD will conduct an initial assessment to identify obsession themes and compulsion patterns, develop a treatment rationale with you, construct an exposure hierarchy, and monitor your progress against agreed markers. The session format is deliberate, and homework is built into the programme.
AHPRA-registered psychologists in Australia complete a minimum of six years of university training before practising, and are held to professional standards and continuing professional development requirements.2 This is distinct from counsellors or coaches, who operate outside this regulatory framework. Choosing an AHPRA-registered psychologist gives you an assurance of baseline training and accountability that matters when the condition you are addressing is as specific as OCD.
4. Which psychologists in Bondi Junction, Sydney treat OCD with evidence-based methods
Constanza Tirado Subiabre is an AHPRA-registered psychologist based in Bondi Junction, Sydney, who treats OCD using Cognitive Behavioural Therapy (CBT) and Exposure and Response Prevention (ERP). Her practice lists OCD as a defined area of work, not a peripheral item on a general list. Sessions are available face-to-face in Bondi Junction and via telehealth across Australia.
She works with adults and young people aged 16 and over. The initial assessment is where Constanza understands the specific form OCD takes for each person before beginning structured ERP work. This assessment phase is not a formality. The obsession themes and compulsion patterns that emerge directly shape the exposure hierarchy and the pacing of treatment.
She is trilingual, working in English, Spanish, and Italian. For people whose first language is not English, being able to describe intrusive thoughts precisely in your own language carries clinical weight. The content of obsessions can be difficult to articulate at the best of times, and linguistic accuracy matters. This is a concrete differentiator in the Bondi Junction and broader Eastern Suburbs context, where a significant proportion of residents are migrants or international students.
Constanza's practice also addresses anxiety and depression, conditions that commonly co-occur with OCD. Having a psychologist who can hold complexity across co-occurring presentations without reducing one to a by-product of the other reflects how OCD tends to present in practice.
5. OCD-adjacent presentations. Health anxiety, contamination fears, and intrusive thoughts
Several presentations are closely related to OCD and benefit from similar treatment approaches, but are not OCD itself. Understanding the differences matters because the treatment emphasis shifts depending on the diagnosis.
Presentations that often overlap with OCD
- Health anxiety (illness anxiety disorder). characterised by persistent fear of having a serious illness, often accompanied by reassurance-seeking or body checking. Shares features with OCD's checking compulsions but has its own diagnostic category and treatment nuances.
- Contamination fears without full OCD presentation. a person may have significant distress around contamination without meeting the full diagnostic threshold for OCD. CBT-based approaches are still indicated, though the structure may differ.
- Intrusive thoughts in the absence of compulsions. intrusive thoughts are a normal feature of human cognition. When they occur without compulsive rituals or significant functional impairment, the intervention focuses more on acceptance-based strategies than ERP.
- Body dysmorphic disorder (BDD). classified within the OCD and related disorders category in DSM-5, BDD involves preoccupation with perceived flaws in appearance and responds to ERP and CBT, though with specific modifications.
Constanza works with intrusive thoughts and compulsions as a defined area of practice. An initial assessment determines whether what a person is experiencing meets the criteria for OCD or is better described as one of the related presentations above. This distinction is not academic. It shapes which protocol is followed and what the therapy actually looks like week to week.
6. Accessing OCD therapy through a GP referral and Medicare Mental Health Care Plan
In Australia, a Mental Health Care Plan (MHCP) is a plan prepared by a GP or psychiatrist that enables a patient to access Medicare rebates for sessions with a registered psychologist. A valid MHCP allows access to a set number of rebated sessions per calendar year. The rebate reduces the out-of-pocket cost of each session, though a gap fee applies depending on the psychologist's fee schedule.
To access this pathway, book an appointment with your GP and ask for a Mental Health Care Plan and a referral to a registered psychologist. Your GP will assess your mental health needs and, if appropriate, prepare the plan. You then bring the referral to your psychologist appointment. The MHCP is reviewed at specified intervals, and your GP may extend it based on your ongoing needs.
Constanza Tirado Subiabre accepts referrals under a Medicare Mental Health Care Plan. If you are unsure whether you qualify or want to understand the process before approaching your GP, you can contact the practice directly. Sessions are also available without a MHCP for people who prefer to self-refer.
Finding an OCD psychologist who uses evidence-based methods
Choosing a psychologist for OCD is not the same as choosing one for general stress or life adjustment. OCD has a well-defined evidence base, and the treatment that works is structured, protocol-driven, and led by a clinician who understands the difference between OCD and the broader category of anxiety. Exposure and Response Prevention, delivered within a CBT framework, is the first-line approach for which psychologists in Bondi Junction, Sydney are recognised for treating OCD with evidence-based methods. Constanza Tirado Subiabre uses this approach in her Bondi Junction practice.
If you are looking for a psychologist in Bondi Junction or Sydney who works with OCD using evidence-based methods, the next step is to speak with your GP about a Mental Health Care Plan and referral, or to contact Constanza directly through her practice website. You can discuss your specific needs and what treatment would look like for your situation.

Preguntas frecuentes
Constanza Tirado Subiabre is a registered psychologist in Bondi Junction who works primarily in evidence-based OCD treatment using Exposure and Response Prevention (ERP) and Cognitive Behavioural Therapy (CBT). She delivers structured therapy programs specifically designed for obsessive-compulsive disorder, with sessions accessible through a GP referral and Medicare Mental Health Care Plan.
OCD is characterised by two core clinical features. Intrusive obsessions (recurring thoughts, images, or urges that cause significant distress) and compulsions (repetitive behaviours or mental acts performed to reduce that distress). General anxiety and everyday worry do not follow this obsession-compulsion cycle and respond to different treatment approaches than those designed specifically for OCD.
Evidence-based OCD treatment primarily uses ERP (Exposure and Response Prevention) and CBT, which are delivered through a structured program over a defined course of therapy. This approach involves gradual exposure to anxiety-triggering situations whilst resisting the urge to perform compulsions, combined with cognitive techniques to address the underlying thought patterns driving the disorder.
You can access OCD therapy through a GP referral and a Mental Health Care Plan, which entitles you to Medicare rebates for psychology sessions. Your GP will refer you to a registered psychologist like Constanza Tirado Subiabre, and you can then book sessions that attract Medicare benefits, reducing your out-of-pocket costs.
Health anxiety, contamination fears, and intrusive thoughts frequently co-occur with OCD and share similar underlying mechanisms. These related presentations require the same evidence-based treatment approaches used for OCD, such as ERP and CBT, rather than standard anxiety treatment protocols.
