"Now we're just going to go back to just having little treats on the weekend, and keeping it up, because we all lost so much weight."
The team comprised Sarah Ridings, Hayley Larkin, Meghan Smith, Michelle Marais and Ms Costello.
Because it was a team effort, the teachers won't reveal who lost what, but said they also made small healthy changes for the children in their care. They thanked the centre's parents and pupils, some of whom gave their pocket money to sponsor the weight-loss effort, raising $210 for the Cancer Society.
Junk Free June is a nationwide fundraiser for the Cancer Society which encourages participants to give up their unhealthy vices for the month.
About $385,000 had been raised by the 11,000 participants as of yesterday, with donations still flowing in.
