Live-in Au Pair - Brisbane

I have 3x children, 2 are at school and my youngest will attend childcare 2-3 days a week. I would require between 30-40 hrs per week (negotiable) and will offer between $300-400 per week, depending on what hours are negotiated. Weekend work will not be required.
I predominately need someone to drop/pickup kids from school (800m away) each day and care for my 2.5 yr old 2-3 days per week (negotiable).
My husband works in Sydney, so it will just be you and i for majority of the time.
You will have a room and access to all within our house (internet/netflix/stan/food).
My kids love being outside and have many toys (pool, trampoline, monkey bars) that keeps them occupied.
We have had a Nanny for a year (who has been the best) but due to her uni schedule is limited in what she can offer.
I am happy to try and negotiate as much as possible to ensure it all works for you.
