NEED YOUR HELP identifying an 80's sitcom

I think it was on from '85 to '87. I don't remember who was in it, or what network it was on, but it was a typical cheesy 80's comedy. It featured a very cute young australian nanny who was hired by a typical suburban family. The show revolved around her keeping the family in line and warding off the advances of the young son.

Does anyone remember this??
