Megan, looking for a nanny in Chatswood

We are looking for an experienced and reliable nanny to get our two daughters to preschool and school 2-3 days per week (hours: 7am-9.30am)
We also need 2 or three long days each month (hours:7am-6pm. One Thursday and one Friday) These days included sole care of our 3 year old and school drop off and pickup for our 5 year old.
Pre-school and school are both nearby, although a car is useful on rainy days and to go to a swimming lesson on the Friday.
Out roster changes week-to-week but is a regular pattern:
Week 1: Tues (7-9.30) Wed (7-9.30) Thurs (7-6pm)
Week 2: Tues (7-9.30) Wed (7-9.30) Fri (7-6pm)
Week 3: Mon (7-9.30) Tues (7-9.30) Wed (7-9.30)
Week 4: Mon (7-9.30) Wed (7-9.30)
