The local team were competing at the international competition in Orlando, Florida.
A spokeswoman said the girls were overwhelmed with happiness, for not only Toxic Cheer but for their country.
“They are on cloud nine at the moment,” she said.
There are 21 girls competed at ICU representing Australia. They were picked from a number of teams that were nominated about a month before leaving to compete at Worlds.
“They had to change their routine to adapt to this competition as well and did it amazingly,” the spokeswoman said.
The Toxic Cheer team will compete at the Cheerleading Worlds tomorrow morning, competing against more than 40 teams in their division.
They have been training since they won the bid to compete last year. They train twice a week for up to eight to12 hours.
The girls have worked with international choreographers also as part of their routine.
Rachel Sherwood and Joshua Coker are their coaches.
The world championships are from April 24 to 26.
There are also two dance teams from Toxic Cheer competing in Florida after they won a bid. The teams are Extreme Pom, coached by Amber Bryan, and Victory contemporary, coached by Sharon Burgess. The dance teams compete tonight and tomorrow.
