Au Pair Required - Opportunity In Australia

hello future AU pair.
We are a young family of 4 + an elderly English staffy wanting to find someone to help us out while both us parents work.
Hubby works full time and I'm needing to go back to work hopefully just part time.
We're looking for someone to mainly help with our very active, gorgeous little toddler while our daughter is at highschool full time.
Toddler; Getting him up in the morning, breakfast, getting dressed, naps, lunch, snacks, parks, playtime , swimming, Picking up big sissy from school And (if I'm not home then dinner, bath & bedtime) but should be only daytime needing your services .
Daughter (12) has sports she will need to get to on Wednesday night & Saturday games.
We have a great spacious private room for you to have with lots of natural sunlight (shared family bathroom though we do have a separate toilet you could have alone if needed) We're hoping you could become part of the family like a big sister more than just an employee.
We're here to help with whatever you need :) And free to spend as much / little with us as you like when you aren't actually "working" You'll only be needed part time so you're absolutely free to do whatever you like at afternoons, nights & weekends.
Etc I'm new to this so would also love your input of what you'd like etc as we're just testing the waters Looking for someone part time but long term would be great!!
:) We're a healthy, low tox, natural , easy going, open minded family hoping to find someone with similar beliefs.etc We're in altona meadows, west side of Melbourne, VICTORIA.
