Based on what you've told us, it looks like you're covered by the Health Professionals and Support Services Award [MA000027].
Employees can’t be directed to take annual leave during a shut down under the Health Services Award, unless they work in dental and medical practices.
An employee can still agree to take annual leave, annual leave in advance or unpaid leave during a shut down.
However, if they don’t agree, they have to be paid their ordinary pay rate for the shut down. They can’t be forced to take unpaid leave.
Employees working in dental and medical practices
Employees working at a dental or medical practice can be directed to take annual leave during a shut down.
If an employee doesn’t have enough annual leave to cover the shut down they can be required to take annual leave in advance, if the requirement is reasonable.
Accumulating annual leave during a shut down
An employee will continue to accumulate annual leave while on paid leave during a shut down period.
