Part-time Nanny Role in Centennial Park

I am looking for some regular part-time help 1.5-3 days a week as well as occasional help with babysitting. Our nanny of 3 years has just let me know she needs to spend more time on university now that she is doing her practicum. We have three kids: Bella is 5, Naomi is 3 and James is 18 months old. We are looking for someone who can spend time with the kids, and do school pick ups (1-2 kids at a time). Ideal days are Tuesday and Friday, but are flexible re hours and days for the right person. We have a full time mother's helper at home, so this is really focused on childcare.

Must be ok with a big dog, and mum who works from home.
