After school nanny / help with pick up

Hello, looking for a kind fun nanny to pick up our 5 year old son from pre-school in Vaucluse at 2.30/2.45pm on Mondays, bring him to Bondi and hang out with him and his 7 year sister at home until 4pm.

Hoping to soon extend to Thursday too, which would be picking up our son as above and then picking our daughter up from Bondi Public After School care (v close to our house) and hanging out with them until 5/5.30pm.
