NDIS-to-NDIS — Visualising participants, providers, workers, budgets and feedback loops, 2013–2036
A static, neutral view of published NDIS data and documented scenario arithmetic, keeping observed rows, official projections, scenarios and hypotheses visually separate.
Published historical counts and audited or reported rows.
Official forecast vintages shown with their original framing.
Slider-driven arithmetic from documented assumptions.
Default-off feedback hypothesis, only shown when enabled.
Participants
774,456 active participants at 31 Mar 2026
Observed active participant counts are shown alongside official participant forecast vintages and the scenario path.
Open ParticipantsCohorts
774,456 participants across post-2025 age bands at 31 Mar 2026
Age-band snapshots and a simple cohort transition show how child-to-adult retention assumptions move through the model.
Open CohortsProviders
277,376 active provider ABNs
Provider counts are separated by published definition so discontinuities remain visible.
Open ProvidersWorkers
325,000 observed workers in 2023
Observed and official projection workforce rows sit beside a scenario worker-per-participant path.
Open WorkersBudget
PBO: $106.7B by 2035–36 under 8% growth
Budget views compare actual participant payments, official forecast vintages and scenario budget measures.
Open BudgetConnected
2,094,837.085 NDIS-connected people in the 2036 default scenario
The connected dashboard combines participants, workers, provider owners and family-linked workers under explicit overlap assumptions.
Open ConnectedLoop
0.0 default feedback strength (hypothesis off)
The loop diagram keeps the provider-density feedback hypothesis default-off and adjustable.
