Let's make this birthday one to remember.

43 years old (Born on September 18, 1981)

Happy Birthday to the legendary Mark Chisholm! From dominating lineouts and charging fearlessly into rucks, you proved your heroic prowess on rugby's biggest stages—most memorably winning the Super 12 championship with the Brumbies back in 2004. Those blistering tries and fierce tackles made opponents tremble (and occasionally duck for cover)!

And who could forget your powerful runs at the grand stage of them all—the unforgettable Rugby World Cup in 2007 representing Australia? Now, as another birthday rolls around, we celebrate those incredible moments you've gifted us—and hope you're tackling birthday cake with just as much spirit today. Cheers, mate!
