Babysitting and Nanny Jobs in Central Macdonald NSW

The Role we are looking for is actually more of a Mothers Helpers (no childcare required).
We are after someone to Assist in household duties such as Washing and folding, Shopping and Food preparation, general house tidy ( Already have a cleaner 1/fortnight), basic errands. Preferably Mondays once a week, but there is flexibility in this (2 shorter days possible - expectation that we need approx 6 hours per week assistance). We have a 3 year old and 2 businesses to run and just need the assistance on the household level to allow us to give more time to him, there is the possibility of babysitting as an extra at times but not expected.

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:

-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)
