Pryce joined the Wiggles organization in 2002, beginning as “one of their main voice artists” on several of their CDs. He joined their regular tour in 2011, as Ringo the Ringmaster and understudying for founding member Murray Cook. He also starred as King John in the Wiggles’ production The Kingdom of Paramithi. In August 2012, Pryce was slated to replace Greg Page as the Yellow Wiggle. However, Page’s departure was delayed until the end of that year, after Cook and Purple Wiggle Jeff Fatt decided to retire from the group then, asking Page to extend his stay until then so he would leave alongside them. Pryce ultimately replaced Cook in early 2013.

In late 2015, Pryce became engaged to ex-gymnast and fitness professional Lauren Hannaford who created online fitness program FHIT. They met four years earlier, when she toured with the Wiggles.

In 2016, the Wiggles released The Carnival of the Animals, its narration was written and performed by Pryce. The album, based on the piece by the French Romantic composer Camille Saint-Saens and performed by the Adelaide Symphony Orchestra, introduced children to classical music and instruments.

Pryce has described himself as “always into fitness and health”, but that the Wiggles’ performance schedule demanded an even higher level. In early 2016, he described his workout routine and the group’s competitive culture of fitness, especially among its male members, to ex-rugby league footballer Adam MacDougall.

Pryce and Hannaford were married in Sydney, in January 2017. On 6 September 2020, they announced that they were expecting their first child.

In September 2020, Pryce was revealed to be the “Puppet” on the The Masked Singer Australia, placing fourth on the second season of the show.
