Babysitter required in Castle Hill

Looking for someone to take care of my daughter (8) and son (5), for after school duties in Castle Hill. We are conveniently located within a ~10 min walk from Castle Towers, which also has the Castle Hill Metro. Duties will include:

-School pickup (~5 min walk from our place)

-Giving them a snack

-Help with homework

-Get them ready (including bathing) - they are quite independent, but need help with getting ready sometimes

-Potentially take them to the local park (~5-7 min drive)

-Meal prep for dinner

Our previous nanny was with us for over 3 years and we are happy to provide a reference. Appreciate if you can get back to us with your relevant experience.

Days will be Tuesdays and Thursdays, approx between 3-7pm.
