In light of recent advancements made in swim suit design and their impact on the sport over the past few years, Swimming Australia announced in December 2008 that it was making changes to the rules concerning swimsuits that could be worn in competition. Swimming New South Wales has now announced it's own changes.

The following changes have been made to Swimming Australia's By-Laws for the conduct of Age Group Events.

CBL14.2 Additional Swimsuit Guidelines for Age Group Events
  1. All swimwear worn by competitors in Age Group Events (18 and under) conducted in Australia by SAL shall be commercially available products.
  2. Swimwear worn by competitors in Age Group Events shall conform to the following design – effective 1 April 2009:
  3. Men’s swimwear is limited to one (1) swimsuit that covers at most the body surface from hips to knee. Swimwear must not extend above the waist or below the knees;
  4. Women’s swimwear is limited to one (1) swimsuit that is of “open back” and “open shoulder” designs that may extend down to the knee. Swimwear must not extend below the knees.
  5. Swimwear must not have a zipper or any type of fastening system.
An Age Group Event is defined as any 18 and under swimming event conducted by SAL under the Australian Championships By-Laws. Currently this includes:
• Australian Age Championships (including Age SWD and Age Open Water), and
• State Teams Age Short Course Championships.

Swimming NSW has now published it's own rule changes for swimwear:
