Part time nanny

We are a family of 2 looking for a nanny for our children (3 year old boy and 6 month old girl) when I return to work. We are looking for someone to look after our 6 month old daughter for 4 hours on Tuesday and Thursday afternoons (1-5pm) and to look after our 3 year old son for 5 hours on Wednesdays. From the end of August, we will need the nanny to look after both children on Wednesdays for approximately 9-10 hours (and hourly rate will increase accordingly). We are located in Wollongong. Ideally you will have had experience in caring for young children and a certificate III in early childhood education.
