They were formed in 1998 to bring entertainment into children's lives with television and live performances — which they have done.
Hi-5 will be bringing their stage performance to the Evan Theatre at Panthers Leagues Club on July 12 and they are inviting families to join the fun.
Hi-5 member Lauren told the Sun it was going to be a show like no other.
"The coolest thing is that it is different. We will have a wheel on the day that we spin and it will pick out the songs we will perform," Lauren said.
"By doing that it makes every show so different, which is great."
The performance is Lauren's last before she takes on acting and fashion, while new member Tanika will also take to the stage for her official first performance.
"She was 19 years old when she first started with us," Lauren said. "She is ready to step up and become a cast member. She loves performing and I know she will enjoy every moment." The school holidays NSW tour will be the first time Hi-5 has six members on stage.
