OutKast are still having fun on their ongoing reunion tour, which is now overseas. The dynamic duo of Big Boi and Andre 3000 traveled to Australia on Thursday (July 25) to headline the Splendour in the Grass festival.

During their time Down Under, 'Kast and their family, including Big Boi's mom, went to the beach to engage in some water activities.

Big Boi decided to jump on a jet ski while Andre 3000 decided to go surfing.

If you check out the photos below you can see that Three Sacks can ride a surfboard. Prior to him hitting the beach, Andre went to the Byron Bay’s Surf School to get a quick surfing lesson.

While gold coastin' in Aussie land, Big Boi also tried to hang out with a wallaby named Lil' Shirley. Unfortunately, the kangaroo-like animal seemed to be more interested in snacking on his food than hanging with Sir Luscious.

After their fun on the beach, OutKast headlined the Splendour in the Grass festival and lit up the concert stage.

According to Australia's Northern Star, the rappers presented a killer show of their classic hits.
