Let's make this birthday one to remember.

49 years old (Born on September 11, 1975)

Happy Birthday, Sally! May your day be filled with more indie pop sparkle than a sold-out concert and sweeter melodies than the ones that earned you ARIA's Breakthrough Songwriter of the Year back in 2008. Clearly, you've been hitting all the right notes ever since!

Here's hoping this year brings even greater inspiration—though topping your past successes might require some serious magic (or at least another catchy tune). Keep dazzling us with those heartfelt lyrics and unforgettable rhythms; after all, birthdays come once a year—but timeless music like yours is forever.

Cheers to many more chart-topping adventures ahead!
