The Sydney Cricket Ground would be covered in pink during the third day of the second Test between Australia and Pakistan.

The initiative will be taken next year to support pace legend Glenn McGrath and his late wife Jane's charity foundation for breast cancer patients.

"Following the outstanding success of last season's Pink 3 mobile Test and Jane McGrath Day in support of the McGrath Foundation, this season's Second Test between Australia and Pakistan at the Sydney Cricket Ground will be bigger and pinker!" Cricket Australia said in a statement.

"Cricket Cares and 3 mobile, together with the SCG Trust and Cricket NSW, have once again joined forces to ensure the SCG is resplendent in pink when the Test is played between January 3 and 7," it added.

Jane McGrath Day was formerly called the Ladies Day.

McGrath, who is the chairman of the Foundation, launched the Pink Test at the SCG today with Australian wicketkeeper Brad Haddin and women's all-rounder Lisa Sthalekar.

"Last summer's Test was an overwhelming success and, with the support of cricket fans and the wider community, we are looking to build on that success in January," he said.

"It costs approximately 350,000 dollars to employ each full-time McGrath Breast Care Nurse over a minimum three year period. In the course of the last 12 months we've grown our nurse numbers from eight back in October last year to now 53," he added.
