Olympian Matthew Mitcham and DJ Dan Murphy got together to record a special duet just in time for Australia Day.

Matt may be known as an international athlete, but he's no stranger to the ukulele too as you can see in his Single Ladies, Family Guy and Rome/Roam videos.
Dan spends a lot of time behind the camera when he's not DJing, making the Bondi Beach, Let's Have A Kiki and Lady Gaga Tribute videos.
