The name of the actress in the iSelect TV ads is

Camilla Borde-Davis. Also known as Milli Davis and Camilla Jackson. You can see her IMDB profile here.

I’m sure this will be a question in a pub trivia night competition sometime soon.

Camiila is known as the iSelect girl, and she pushes the iSelect insurance company product.

She can also be seen in the Jim Bean “The Stalker” ad.

Update March 2013:
The Ad Agency responsible for the iSelect concept was Starship. You can see copies of the iSelect Girl videos on their website here.
