Sydney's Opera House turns pink

The Sydney Opera House will be flushed pink to show support for Australian women diagnosed with breast cancer.

As the McGrath Foundation celebrates 10 years of placing breast care nurses in communities across Australia and increasing breast awareness in young people, the Opera House will light up on Wednesday night.

In the past decade, the foundation has supported more than 36,000 families through the challenges of breast cancer.

It costs more than $13 million each year to fund 105 breast care nurses, according to the foundation.
