Rosemount Australian Fashion Week's only guidelines over body image state: "RAFW does not currently see the need to impose strict rules on designers regarding the casting of models at the event in relation to imposing body mass indexes ...there has been very little cause for concern regarding the issue."
Lock said the "size zero" debate was just not an issue in Australia where most models tend to have higher BMIs given a range of environmental factors.
"The models we have at Australian Fashion Week are beautiful and athletic," he said.
The event did, however, this year ban models aged under 16 from appearing on the catwalk after uproar over plans to feature 14-year-old Polish model Monika Jagaciak.
Ward said there was a lot of pressure in the fashion industry outside Australia for models to be extremely thin.
"In Australia we have a much healthier attitude towards body image and such an outdoor lifestyle that the girls here are usually one size larger," she said.
