The last one it was as Au Pair in Auckland. The main activity is keep the children safe. The kids who were being taken care of were 5 years old (girl) and 8 years old (boy). The job relates to make breakfast, lunch and dinner for the kids. Drive them to the bus stop and to some activities that they have (swimming classes, dancing classes, scouts, etc.) After school they need to do their homework so the Au Pair has to help and supervise them. As well as organize games and recreational activities so they enjoy the afternoon and evening until the parents come back home. In Chile I had more experience with care of children.
