Since Emma Wiggle announced she would be passing the iconic yellow skivvy onto someone new, 15-year-old dancer Tsehay Hawkins, we have become mildly obsessed with looking back at The Wiggles' history and how they have evolved over the years.

One of the most beloved children’s entertainment groups, The Wiggles have left an indelible mark on generations past and present - not only in Australia but across the globe.

Whether it’s how the group started, the insane amount of money they have earned, or the super strict rules all members must follow, here are 12 fun facts you definitely didn’t know about The Wiggles.

Let’s hop in the big red car, and away we go!

How The Wiggles started.

It all began with a young Anthony Field, the only original member to still be in the current group.

The Blue Wiggle went to complete his degree in Early Childhood Education at Macquarie University in Sydney. It’s where he went on to meet his fellow future group mates, Greg Page the Yellow Wiggle and Murray Cook the Red Wiggle. Purple Wiggle Jeff Fatt soon came on board as well, the four of them deciding to busk together.

In 1991, while still at uni, Anthony decided to write a children’s album. It was a project that he would dedicate to his late niece. One of those songs was called, ‘Get Ready to Wiggle.’ And the rest is history.

Anthony knew he was onto something when he gave a copy early on to one of the mums of the preschool where he was teaching and she gave him some good feedback. “The next day a lady came in and said, ‘I want to strangle you. 43 times my child played Dorothy the Dinosaur’.”

Their first album cost just $4,000 to make and sold 100,000 copies.

The band would perform during the school holidays when they had time off from their real jobs, taking the act around Sydney and NSW. They would perform at daycare centres and shopping malls, often with fellow ABC children’s programming talent.

When their popularity grew, The Wiggles started doing their own gigs.

Within a year of officially forming, they were Australia’s most popular children’s entertainers, and a few years after that, they were touring the US.

They also opened their own recording space called Hot Potato Studios and have a big red car ride at Dreamworld on the Gold Coast.

The Wiggles are proud supporters of Red Nose Day, for a very personal reason.

For 30 years, The Wiggles have made it their mission to help Red Nose Australia raise much-needed funds and awareness for eradicating sudden and unexpected death in infancy in Australia.

There’s a personal reason why Red Nose Day is of such great importance to the group.

Before they were Wiggles in the 1980s, Anthony Field and Purple Wiggle Jeff were in a rock band called The Cockroaches. The band broke up when Anthony’s brother and fellow bandmate Paul Field lost his infant daughter to SIDS in 1988, otherwise known as sudden infant death syndrome.
