To stay compliant with CASA and keep your crew safe, here are the key practices every aviation operator should follow:

- Run training programs so your crew understands testing procedures, and how to stay safe.
- Always conduct drug and alcohol testing as part of your pre-employment process.
- Perform regular, unannounced drug and alcohol tests to deter use.
- Test after any incident.
- All testing should follow Australian standards to ensure accuracy.
- Consult a Medical Review Officer (MRO) after positive test results.
- Make sure your policy outlines exactly what happens if someone tests positive.
- All drug and alcohol testing results must be handled discreetly.
