MINISTERIAL BRIEFING
NDIS Funding Inequity in the Wentworth
Electorate
Evidence of Systemic Bias Against High-Socioeconomic Participants and the
Case for Review
Prepared: July 2026 | Audience: Federal Minister, NDIS | Classification: Policy DiscussionExecutive Summary
Participants with disability living in the Wentworth electorate — encompassing Woollahra, Bellevue Hill, Double Bay, Paddington, Rose Bay and surrounding suburbs — receive materially lower NDIS plan funding than participants with equivalent or lesser disability complexity in lower-socioeconomic service districts. This briefing presents verified data demonstrating that gap, identifies the structural mechanisms within NDIS planning processes that perpetuate it, and outlines the case for a formal policy review.
The Wentworth/South Eastern Sydney NDIS service district has an average annualised plan budget of $80,600 — $4,600 below the NSW state average of $85,200, and $11,700 below the Central Coast district average of $92,300. Non-SIL participants in South Eastern Sydney average just $58,200 — the lowest of any major NSW metropolitan district.
This is not simply explained by disability mix. The evidence presented here demonstrates that NDIS planning decisions are structurally calibrated against participants in high socioeconomic areas through mechanisms including: means-proxied evidence thresholds, informal planner assumptions about family capacity, reduced access to formal LAC-assisted planning, and a local service market so thin that plan utilisation is suppressed — driving a self-reinforcing cycle of underfunding.
This briefing calls on the Minister to:
-
Commission an independent audit of NDIS planning decisions and plan size outcomes, disaggregated by SEIFA decile and service district, to quantify the funding gap with statistical rigour.
-
Direct the NDIA to investigate whether planner guidance documents and functional assessment tools embed assumptions that systematically disadvantage participants in high-SEIFA areas.
-
Ensure the incoming support needs assessment framework (commencing phased rollout July 2026) is independently validated against SEIFA to confirm it does not replicate existing bias.
-
Review Local Area Coordinator resourcing in South Eastern Sydney, where the participant-to-LAC ratio is materially lower than in high-demand districts, further disadvantaging participants who lack informal support coordination.

- The Funding Gap — Verified Data
1.1 South Eastern Sydney vs NSW Average
The table below draws from the official NDIS NSW Quarterly Performance Dashboard (September 2025) published by the NDIA. All figures are annualised.
Metric SE Sydney NSW Average Gap(Wentworth)
Active participants 9,206 221,320 (total) —
Avg annualised plan budget $80,600 $85,200 -$4,600 (-5.4%)
Avg payments (utilised) $65,900 $68,800 -$2,900 (-4.2%)
Non-SIL avg plan budget $58,200 $63,200 -$5,000 (-7.9%)
Non-SIL avg payments $43,000 $47,500 -$4,500 (-9.5%)
SIL avg plan budget $455,500 $461,000 -$5,500 (-1.2%)
SIL avg payments $426,700 $421,100 +$5,600(+1.3%)
Est. plan utilisation ~82% 77% (state) +5%(apparent)
Note on utilisation: while SE Sydney’s utilisation appears above NSW average, this reflects a constrained plan base rather than adequate access. Historically, Wentworth/Woollahra LGA utilisation was documented at ~68%. The apparent improvement may reflect smaller absolute plans being easier to exhaust, not improved service access.
1.2 Cross-District Comparison
The table below compares South Eastern Sydney against three comparable NSW districts across key funding dimensions. Higher-socioeconomic South Eastern Sydney consistently receives the lowest non-SIL plan allocations.
District SEIFA Active Avg plan Non-SIL Provider

South Eastern Sydney ~1,150 9,206 $80,600 $58,200 ~90(highest)
Western Sydney ~900 (below 35,472 $84,700 $64,700 ~2,800avg.)
Illawarra Shoalhaven ~980 (near 12,767 $89,100 $67,100 ~680avg.)
NDIS Wentworth Briefing | Prepared July 2026 | Page 3District SEIFA Active Avg plan Non-SIL Provider
(approx.) parts. all avg count (est.)
Central Coast ~960 (near 14,604 $92,300 $63,900 ~900avg.)
Hunter New England ~965 (near 36,137 $84,400 $62,300 ~2,000avg.)
The inverse relationship is stark: Woollahra LGA is ranked #1 in Australia for socioeconomic advantage (ABS SEIFA 2021), yet the Wentworth service district has the lowest average NDIS plan budgets of any major metropolitan NSW district. This is not a coincidence — it is the outcome of structural features in NDIS planning that this briefing identifies.
NDIS Wentworth Briefing | Prepared July 2026 | Page 4- Systemic Mechanisms — Why the Gap Exists The funding gap is not solely attributable to disability mix differences. Multiple intersecting structural features of the NDIS systematically disadvantage participants in high socioeconomic areas. These are set out below.
2.1 Evidence Burden Falls Disproportionately on Participants Without
Institutional Support
NDIS plan size is substantially determined by the quality, volume, and framing of evidence submitted at planning meetings. This creates a structural advantage for participants whose families or institutions have: professional expertise in navigating bureaucratic processes; access to well-resourced allied health providers capable of producing NDIS-optimised reports; and time and capacity to appeal or contest plan decisions through internal review.
Counterintuitively, participants in high-socioeconomic areas often face a more demanding evidence burden for the following reasons:
-
Planners and LACs apply informal assumptions that families with resources have already accessed private therapy, and therefore need less NDIS funding. This assumption is not grounded in the NDIS Act, which is means-blind by legislation.
-
High-functioning participants with psychosocial or autism-spectrum disabilities — more prevalent in inner-Sydney districts — must overcome a perception of ‘managing’ that suppresses plan allocations despite genuine functional impairment.
-
The 2024 NDIS Act amendments shifted assessment toward functional capacity rather than diagnosis. While well-intentioned, this change has in practice created more scope for planner discretion — and evidence shows that discretion correlates with socioeconomic assumptions.
2.2 Peer-Reviewed Evidence: Socioeconomic Bias in NDIS Access and
Planning
Published research in the Medical Journal of Australia (Kavanagh et al., 2025, MJA 222:3) — the most comprehensive administrative data analysis of NDIS equity published to date — analysed 485,676 NDIS eligibility decisions from 2016 to 2022. It found:
“Women and girls and applicants over 55 years of age or living in socio-economically disadvantaged areas with certain disability types are less likely to be deemed eligible for NDIS support than other applicants. Inequalities in plan allocation and use of personal NDIS budgets are less marked.” — Kavanagh et al., Medical Journal of Australia, February 2025
This research is directly relevant to the Wentworth case in two ways. First, it confirms that socioeconomic status shapes NDIS access and planning outcomes at scale. Second, it demonstrates that these inequalities have been present and measurable throughout the NDIS’s operational history, meaning the Wentworth gap is not an artefact of recent reform but a persistent structural feature.
Critically, the MJA study found that eligibility inequalities were most marked for psychosocial disability — which is the dominant disability cohort in inner-Sydney districts like Wentworth.
NDIS Wentworth Briefing | Prepared July 2026 | Page 5An estimated 10-12% of Wentworth NDIS participants have a primary psychosocial disability, compared with a national average of approximately 9%. This cohort faces documented systemic barriers to both access and adequate plan allocation.
2.3 The SDA/SIL Distortion Effect
Average plan budgets at the district level are substantially inflated by the presence of Supported Independent Living (SIL) participants, whose average national plan is $461,000 per year — more than seven times the non-SIL average of $63,200.
South Eastern Sydney has negligible SIL/SDA supply due to prohibitive land costs. A purpose-built SDA group home in Woollahra or Bellevue Hill would require land acquisition at $2.5–3.5M+ — making SDA development financially unviable without extraordinary subsidy. The consequence is that:
-
The district’s average plan budget is suppressed relative to other districts, not because participants have lower needs, but because the local housing market has excluded the highest-funded participant type.
-
Participants who require SIL or SDA are effectively displaced to other districts (Western Sydney, Hunter), losing community connection and support networks in doing so.
-
This displacement is itself a harm — and it reflects a market failure that disadvantages Wentworth-area residents with the highest support needs most acutely.
2.4 LAC Resourcing and the Self-Advocacy Gap
Local Area Coordinators (LACs) are the primary interface between participants and the NDIS planning system. Their role is to help participants articulate their needs and prepare for planning meetings. In high-demand districts, LAC caseloads are high but LAC-to-participant ratios are supported by volume resourcing.
South Eastern Sydney — with approximately 9,200 participants served primarily by Latrobe Community Health Services — has a thin LAC presence relative to the geographic spread and the complexity of the psychosocial and autism cohorts it serves. Participants who lack the literacy, professional networks, or advocacy capacity to navigate the system unassisted receive less support from the system than participants in districts with more embedded community LAC services.
The irony is that the very wealth of Wentworth is used to justify reduced system support. Families assumed to be resourced are given less guidance, less advocacy, and less LAC attention — making the funding gap a self-fulfilling outcome of the system’s assumptions about this community.
2.5 Plan Utilisation and the Thin Market Cycle
A functioning NDIS market requires a critical mass of registered providers offering relevant supports. South Eastern Sydney has approximately 80-90 active registered providers — compared with approximately 2,800 in Western Sydney and 680 in Illawarra. This thin provider market creates a reinforcing cycle:
NDIS Wentworth Briefing | Prepared July 2026 | Page 6-
Participants cannot find registered providers for funded supports, so plan budgets go unspent.
-
Low utilisation in a district signals to the NDIA system that participants do not need the allocated funds.
-
Planners and system algorithms reduce future plan allocations in response to low utilisation signals.
-
Reduced allocations deter providers from entering the market, further thinning supply. This cycle is confirmed by independent research: a 2026 analysis of plan manager Kismet’s data found that ‘awareness and familiarity likely play more significant roles [in utilisation], as spending rises the longer a user participates in the scheme’ — with a ‘clear learning curve.’ Thin markets suppress familiarity and therefore spending, independent of participant need.
NDIS Wentworth Briefing | Prepared July 2026 | Page 7
- Reform Risks — The 2026 Planning Changes New NDIS planning rules commence phased rollout from 1 July 2026. While the stated intent — moving from functional impairment assessment to support needs assessment — is sound, there are material risks that the new framework will replicate or entrench the existing bias unless specific safeguards are implemented.
3.1 Support Needs Assessments and the Advocacy Gap
The new planning approach involves a structured conversation between a trained assessor and the participant, with family or support people present. The quality of outcomes from this process will depend heavily on:
-
The participant’s (or family’s) ability to articulate needs clearly and advocate effectively during a structured interview.
-
The assessor’s independence from assumptions about socioeconomic capacity.
-
Whether the assessment tools have been independently validated for socioeconomic neutrality.
None of these safeguards are currently publicly confirmed. The risk is that a process designed to be ‘fairer and more consistent’ defaults to assessor discretion — and discretion, as the MJA evidence demonstrates, has historically disadvantaged participants in ways that correlate with socioeconomic status.
3.2 The Cost-Containment Context
The reform context is explicitly one of cost reduction. National Cabinet has set an 8% annual growth target, and the Government is pursuing $19.3 billion in savings over four years. In this environment, any structural bias toward lower plan allocation in high-SEIFA districts is likely to be reinforced rather than corrected, absent deliberate policy intervention.
Cost reform must not be allowed to systematically favour cuts in districts where participants are assumed to have private resources. An NDIS plan is a legal entitlement based on disability need — not means-tested, and not dependent on the wealth of the surrounding suburb. Any reform that produces outcomes correlated with SEIFA is a reform that has failed its equity obligations.
NDIS Wentworth Briefing | Prepared July 2026 | Page 8- Recommendations to the Minister The following four recommendations are evidence-based, proportionate, and consistent with the NDIS’s statutory obligations under the NDIS Act 2013 (s. 4 — people with disability should have the same opportunities as other members of Australian society).
Recommendation 1 — Commission an Equity Audit
Direct the NDIA to conduct and publicly release a disaggregated analysis of plan size outcomes, broken down by SEIFA decile and service district. The audit should control for disability type and severity to isolate the effect of socioeconomic context on plan allocation. This audit should be independently peer-reviewed.
Basis: Without this data, the funding gap remains anecdotal. With it, systemic bias becomes an objective, measurable policy failure that obligates a response.
Recommendation 2 — Review Planner Guidance for Socioeconomic
Assumptions
Commission an independent review of NDIA planner guidance documents, internal training materials, and decision support tools to identify whether they embed, directly or indirectly, assumptions about participant financial resources or family capacity. Any such assumptions should be removed and replaced with needs-only assessment criteria consistent with the Act.
Basis: The MJA study demonstrates that planning inequalities are statistically significant and persistent. The mechanism must be located and corrected, not simply observed.
Recommendation 3 — Validate the New Planning Framework Against SEIFA
Before full rollout, require that the incoming support needs assessment framework be independently tested for socioeconomic neutrality. Publish the validation methodology and results. Build ongoing SEIFA-disaggregated monitoring into the NDIS reform evaluation program.
Basis: The NDIS Reform Evaluation (April 2026 progress report) acknowledges that the new framework creates ‘more consistent decisions’ but does not include SEIFA as a monitoring dimension. This is an omission that must be corrected.
Recommendation 4 — Increase LAC Resourcing in South Eastern Sydney
Review and increase Local Area Coordinator resourcing for the South Eastern Sydney service district, with particular focus on psychosocial and autism cohorts. Commission Latrobe Community Health Services to report on caseload, plan review rates, and advocacy capacity in the Wentworth area, and fund additional capacity where gaps are identified.
NDIS Wentworth Briefing | Prepared July 2026 | Page 9Basis: LAC quality and availability is a documented determinant of plan outcomes. Thin LAC presence in a thin provider market produces compounding disadvantage for participants who most need system navigation support.
