The Hidden Cost of NDIS Agency Turnover
When the agency sends a different worker every few weeks, the real cost is not on the invoice. What constant turnover takes from the person you support, and what going direct changes.
Short answer
With an agency you often get whoever is available, which can mean a different worker every few weeks. The cost that never shows up on the invoice is borne by the person you support, who starts over with a stranger each time, and by you, who re-explains everything. Your own small team trades that churn for consistency, and a flat-fee tool replaces the per-hour cut.
Agencies and marketplaces have their place, especially when you are starting out and need someone quickly. But once you have been through a few rounds of “here is your new worker”, the real price of constant turnover becomes clear. Most of it never appears on a bill.
Why agencies churn through workers
This is not about blaming agencies. It is how the model works. Staff are pooled and shifts are filled from whoever is free, workers are often casual and move between clients, and the agency's job is to fill the slot rather than to protect one relationship. So the same Tuesday shift can be a different face most weeks, and nobody is really at fault.
The costs you can see, and the ones you cannot
The visible cost is the margin: an agency rate or a marketplace cut of 15 to 20 percent on top of the wage, on every hour, forever. That one is on the invoice.
The hidden costs are larger, and they land on the people least able to carry them:
- The person you support has to build trust again from zero, often with someone who does not yet know their routines or what keeps them calm.
- You become the only thread of continuity, re-explaining the same details to each new worker because the knowledge never stays in one place.
- Inconsistent support can mean more distress and, for some people, more incidents, which costs far more than any hourly rate.
What consistency is actually worth
For many people with disability, the same trusted worker is not a luxury. It is the support. A familiar person who knows the routines and reads the small signs does better work, and the person they support is steadier for it. When you measure an agency only by its hourly rate, you miss the thing that matters most.
Does going direct mean more work for me?
Honestly, it means taking on the coordination the agency used to do: rostering, confirmations, notes and keeping checks current. That is a real trade. The difference is that you keep the relationship, you keep your data, and you stop paying a cut of every hour. And the coordination is exactly what a tool is for, so it does not have to land back on your kitchen table. We cover the day-to-day in rostering your own workers without an agency and the move itself in going direct.
How Sparks Flow changes the maths
Sparks Flow is one flat annual fee with no cut of wages, so the cost stops scaling with every hour your workers do. You bring your own small team, keep their history in one place, and the person you support gets the same familiar faces instead of a rotation of strangers.

Sparks Flow is the tool for running your own support team: one flat annual fee, no cut of wages, and if you self-manage you may be able to fund it from your plan. Start a 14 day free trial.
Frequently asked questions
Why does my agency keep sending different support workers?
Agencies staff from a shared pool and fill shifts with whoever is available, so the same shift can go to different people week to week. It is a feature of the model, not the fault of any one worker. Going direct with your own small team is what gives you consistency.
Is it cheaper to hire my own support worker than to use an agency?
Often, yes, because you stop paying a margin or a per-hour cut on top of the wage. You take on the coordination yourself, which a low-cost tool can carry. The bigger saving is usually continuity rather than dollars.
What is the problem with a different worker every shift?
For many people, especially those with disability, a trusted and familiar worker is part of the support itself. Constant change means starting over each time, lost routines, and more distress. Consistency is a quality issue, not just a convenience.
Can I move from an agency to running my own team?
Yes. Self-managed and plan-managed participants can engage workers directly. You can often keep workers you already like and add your own, then manage them in one place. Check the terms of any platform you are leaving.
Does Sparks Flow take a cut of wages?
No. Sparks Flow is one flat annual fee. It never touches wages and never takes a percentage of hours worked.
