Helper for expat family

We are an Australian family of four (2 adults, 10yr old + 6yr old) who have lived in Singapore for 20 years. Husband travels for work twice a month. Wife works part-time. Our children catch the bus to and from school, and have various after school activities. Helper is sometimes required to send children to activities in a taxi or bus. Main duties include good housekeeping and laundry, supermarket, cooking healthy western and asian meals, school and afternoon snacks for children. We also have a gentle lovable 3 yr old dog who needs a weekly bath. We are looking for someone who is experienced with a busy expat household and has a good knowledge of expat life in Singapore. Someone who enjoys working with primary aged children, is patient, trustworthy, and able to follow recipes. Must also be respectful in our home, and can manage the house and dog when we travel. Our current helper has been with us for over 6 years, but now prefers to work with a younger family. We give all Sundays off, and some public holidays. We prefer minimum of 8 years experience in Singapore, and offer a generous salary plus incentive.
