MUMS Kate "Stitch Em'up" Hughes and Christy "Fennder Bend'er" Fenn are part of a unique group of women.
They are stay-at-home mums, high-flying professionals, in their late teens and in their mid-40s.
What brings together this diverse group of women?
The bumping, bruising, full-of-attitude sport that is roller derby, that's what.
The Hervey Bay Rollerz have been bumping around for 18 months, but with the group now bigger than ever - and faster and meaner - they are growing out of their venue at Yarrilee State School, where they moved after graduating from the slower surface of the Hervey Bay PCYC.
Rollerz president Annette Thorogood said while they had been grateful to Yarrilee for the use of the school's hall, it only just fit the track, which sometimes made for hairy moments with the more advanced skaters risking flying into brick walls.
"Yarrilee hall is fantastic in terms of the floor surface - it's awesome - but it's very small for the sort of track we need," she said.
"We need some room to move so that's not going to be a safety issue."
Annette said the ideal venue would have an open area larger than a basketball court, with a concrete or timber floor.
