Every NDIS and aged care provider reaches a point where they need to decide: when a shift cannot be filled from their direct workforce, do they call an agency? The immediate answer is usually yes. The problem is that a decision made shift by shift, in the middle of an operational crisis, is rarely the right long-term strategic decision.
The agency invoice rate is the visible cost. For disability and aged care support workers, agency rates in Australia typically range from $45 to $75 per hour depending on time of day, service type, and location. Your direct employment cost for the same worker — including base rate, superannuation, leave loading, and SCHADS penalty — might be $35 to $55 per hour.
But agency workers do not know your participants. A support worker encountering a participant for the first time takes significantly longer to complete the same tasks, is less likely to notice subtle changes in the participant's presentation, and is less able to de-escalate behavioural situations that a regular worker would manage. There is also a compliance dimension — agency workers have generally received a brief handover at best.
For providers with a stable baseline of participant hours, direct employment for the core of that delivery is structurally cheaper than agency for all but the smallest organisations. The fixed employment costs are amortised across a reliable volume of billable hours, and the per-hour loaded cost falls below the agency rate. The variable top — additional hours arising from new participants or increased service levels — is where a pool of casual direct employees, managed with good availability systems, is typically cheaper than agency labour.
The optimal answer is a tiered approach: a core of permanent employees for predictable, ongoing participant hours; a pool of engaged casual employees for variability and planned leave cover; and agency as a genuine last resort rather than a first call. Moving to this model requires investment in a rostering system that gives casual employees genuine visibility of available shifts, an availability management system, and an open shift marketplace that distributes unfilled shifts to the eligible pool before any consideration of agency engagement.
