Let's make this birthday one to remember.

46 years old (Born on April 02, 1979)

Happy Birthday, Mark Donaldson! You're the only guy we know who can casually mention receiving a Victoria Cross as if it were just another day at work. Your bravery during Operation Slipper and the Battle of Khaz Oruzgan has set an impossibly high bar for birthday stories—seriously, how are any of us supposed to compete with that?

But beyond your legendary courage in uniform, you're also known for being humble enough to laugh off heroics like they're no big deal. Here's hoping this year brings you plenty more adventures (preferably less dangerous ones), endless laughs, and cake worthy of Australia's bravest soldier!
