Murray is the original red Wiggle and the original lead guitarist in The Wiggles, known as the "king of guitars". He was the red Wiggle for 21 years before being replaced by Simon Wiggle in 2013. He has since made cameos in some episodes of Ready, Steady, Wiggle! and still occasionally performs in the reunion concerts.
He loves playing guitar, as he does off-screen, and is also considered the best musician of The Wiggles. Unlike the other three Wiggles, he only played guitar during his tenure (along with guitar-adjacent instruments, like the mandolin and ukulele), but he also played other instruments like the flute or the trombone on occasions. In some later videos, he played guitar in many songs rather than dancing. This happened starting with some of the late Sam videos and continued during the Celebration era. He plays guitar throughout the concerts except for a few select songs. He eats pancakes for breakfast, and his favourite food is bananas.
- His favourite guitar that he used to play in the early days is the Red Starry Guitar.
- He owns a collection of thirty vintage guitars.
- He created the group's signature finger-wagging move.
- He is the only original Wiggle to have never been involved with The Cockroaches.
- He is the second tallest Wiggle of the original generation (6'3).
- He is absent in two songs Oranges And Lemons and Wags The Dog, He Likes To Tango (2012 version).
- He and Paul Knobloch were waiters.
- In Spanish he is voiced by Mario de Candia.
- In Walking On The Moon (episode), Lachy wore his spacesuit.
- He is the only Wiggle who is realistic because he plays guitar the most.
