On Monday night, ABC’s Four Corners aired “Attention Deficit,” mapping ADHD diagnosis rates across Australia for the first time. The same week, AIHW data confirmed what clinicians have suspected for years: women now outnumber men on ADHD medication in every adult age group. The story framed it as a boom. The clinical reality is more specific than that.

How the ADHD community responded
Within hours of the episode airing, Australian ADHD communities lit up. The r/ausadhd subreddit (30,000+ weekly visitors) had multiple threads with hundreds of comments. The overwhelming response was frustration.
People who spent years getting diagnosed felt the episode questioned the legitimacy of their condition. Women who waited decades for an assessment felt their experience was erased by an overdiagnosis narrative that never acknowledged the decades of underdiagnosis that came before it. Parents who fought to get their children assessed felt the episode painted them as gullible.
Several recurring themes stood out:
- The episode implied a pipeline from TikTok to diagnosis to medication, without acknowledging that increased awareness is how historically missed populations get found.
- Geographic “hotspots” were flagged without examining why. Fremantle, for example, was highlighted as having high diagnosis rates. Locals pointed out it is a bohemian, creative community where artists and musicians cluster. People with ADHD tend toward creative professions. The correlation was not explored.
- The cost and access barriers were acknowledged but not given proportionate airtime. $1,400 average assessment costs. 12-month wait lists. Regional Australians with no local clinicians. These are the structural problems.
- Multiple people reported that family members who watched the episode now doubt their diagnosis. The real-world consequence of overdiagnosis framing is that people stop seeking help.
One comment captured the sentiment that many shared: “QLD is leading the way with GPs. I hope other states follow.”

What the AIHW data shows
The Australian Institute of Health and Welfare tracks every PBS prescription dispensed in the country. Their latest data (2023-24) shows:
- Women overtook men in ADHD prescription rates in the 18-24 and 25-44 age groups for the first time in 2022-23.
- By 2023-24, female rates exceeded male rates across all adult age groups (18-24, 25-44, and 45+).
- Female prescription rates increased five-fold in five years (from 4 to 19 per 1,000 population between 2018-19 and 2023-24). Male rates doubled in the same period (11 to 26 per 1,000).
- 4.6 million ADHD prescriptions were dispensed to approximately 600,000 patients in 2023-24.
The overall population rate went from 2 per 1,000 in 2004-05 to 22 per 1,000 in 2023-24. Most of that growth happened in the last five years.
Children and adolescents still show higher rates in boys (9% of males aged 12-17 vs 5% of females). The crossover happens in adulthood. This pattern tells you something: boys get picked up at school. Girls get picked up decades later, if at all.
Why women are being diagnosed now and not 20 years ago
ADHD in women presents differently from the stereotypical hyperactive boy in a classroom. The diagnostic criteria (DSM-5) were built on research that overwhelmingly studied males. Women with ADHD are more likely to present with inattentive symptoms: difficulty sustaining attention, losing things, forgetting appointments, struggling with time management, internal restlessness rather than physical hyperactivity.
These symptoms get misread. Depression. Anxiety. Burnout. Personality disorder. A 2026 Monash University study published in the Journal of Psychiatric Research found evidence of systemic underdiagnosis of females, suggesting the historical male-to-female ratio (3:1 to 4:1) reflects detection bias, not actual prevalence. The true ratio is likely closer to 1:1.
Associate Professor Caroline Gurvich, who led the Monash research, noted: “For some women, this could reflect a lack of recognition of ADHD beyond the traditional male-centric model.” The study found that females are more likely to experience internalised symptoms like inattention, which are overlooked or mistaken for other conditions.
The five-fold increase in female prescriptions is not women suddenly developing ADHD. It is clinicians finally recognising it in women who have had it their entire lives.
Increased awareness is not the same as lowered diagnostic standards. Women finding information online and recognising their own symptoms is not a flaw in the system. It is the system finally reaching people it missed for 30 years. The clinical bar for diagnosis has not moved. What moved is who walks through the door.
The geographic divide: who gets assessed and who doesn’t
Four Corners mapped what the AIHW numbers confirm at a postcode level:
- Least disadvantaged areas: 30 prescriptions per 1,000 population
- Most disadvantaged areas: 16 per 1,000
- Inner regional areas: 25 per 1,000
- Remote and very remote areas: 14 per 1,000
Four Corners reported that in some parts of Australia, up to 90% of adults who likely have ADHD remain undiagnosed and untreated.
This is not because ADHD is more common in wealthy suburbs. It is because access to assessment is concentrated there. Psychiatrists are concentrated in capital cities. Private psychologists charge $500+ for an assessment. Wait times average 10 weeks, stretching to 12 months in some areas. The University of Wollongong found the average total assessment cost is nearly $1,400. We break down those costs in detail in our comparison of ADHD assessment options and pricing in Queensland.
If you live regionally, or you cannot afford a private assessment, or you have been on a wait list for months, the system has a gap. That gap is what the Queensland GP prescribing reform addresses.
What a structured ADHD assessment looks like through a GP
Since December 2025, GPs in Queensland with a Schedule 8 prescribing authority can assess and treat adult ADHD without a psychiatrist referral. South Australia followed in February 2026, and other states are on track.
A structured GP assessment uses the same validated tools psychiatrists use (ASRS v1.1 screening, clinical interview, collateral history from someone who knows you). The difference is access: shorter wait times, Medicare rebates apply, and telehealth means your location does not determine your care. We explain exactly how a telehealth ADHD assessment works from start to finish.
A thorough assessment includes:
- Validated screening questionnaires (not a 5-minute online quiz)
- Detailed developmental history, including childhood symptoms
- A collateral report from someone who knows you well (partner, parent, close friend)
- Medical history review to rule out other explanations
- Mental health screening for differential diagnosis
- Functional impact assessment across work, relationships, and daily life
This is the same clinical standard a psychiatrist applies. The GP pathway makes it accessible without the 12-month wait or the $1,400 price tag.

FAQ
Does the rise in women’s prescriptions mean ADHD is being overdiagnosed in women?
No. The evidence points in the opposite direction. Women have been systematically underdiagnosed for decades because diagnostic criteria were built on male presentations. The current increase represents women finally accessing assessment, not a lowering of diagnostic standards. AIHW data shows that in children, boys are still diagnosed at nearly twice the rate of girls. The adult crossover suggests women are being identified later in life after years of missed diagnosis.
How long does a GP ADHD assessment take?
A structured GP assessment typically involves completing intake questionnaires before your appointment (which you do from home, on your phone, at your own pace), followed by a clinical consultation. The pre-appointment preparation means the GP has your full history before you walk in. The consultation itself focuses on clinical assessment rather than paperwork.
Do I need a referral to see a GP for ADHD assessment?
No. You do not need a referral to see a GP. You can book directly. In Queensland, GPs with a Schedule 8 authority can assess and prescribe ADHD medication without needing to send you to a psychiatrist.
Is a GP assessment less thorough than a psychiatrist assessment?
A structured GP assessment uses the same validated instruments and diagnostic criteria (DSM-5) as a psychiatrist. The difference is access and cost, not rigour. GPs who conduct ADHD assessments using structured intake processes collect validated questionnaire data, collateral history, developmental history, and differential screening before the clinical consultation.

What does an ADHD assessment cost through a GP?
Standard GP consultations attract a Medicare rebate. Your out-of-pocket cost depends on your GP’s billing structure. Most patients pay significantly less than the $1,400 average assessment cost reported for private psychiatrist and psychologist pathways.
