Hitting the peak of her fame in the late 1970s and early 1980s, who is the British-Australian beauty in this photo?

Now, you might recognize this Australian beauty as Sandy from Grease, but her resume extends far beyond that single role. She is also a credited singer, songwriter, actress, entrepreneur, and activist. Her hit song "Physical" from 1981 spent 10 weeks on top of the Billboard charts.
