You need to inform your employer of your intention to take parental leave. Specific requirements for doing this vary between states, agreements and awards. It is therefore important to confirm the procedure in your workplace. Regardless of the legal requirement, the earlier you provide the notice, the more time you and your manager have to plan the transition.
As a guide, you are required, approximately 10 weeks prior to the expected birth, to notify your employer in writing of your intention to take maternity / paternity leave.
At this stage you also need to confirm how long you plan to take (up to a maximum of 52 weeks) leave.
Discuss your required leave period with your manager once you have provided formal notification – you may change your mind after your child is born.
