THE competition in the Zoo Weekly Australian Swimsuit Calendar Search is warming up after the third round finalists were announced before tonight's fourth and final heat.
Leandi Booysen, Vanessa Coonan and Shaylee Smith took out the honours in round three, impressing the judges with their theme wear.
Ms Coonan was a definite crowd favourite, conjuring her dark side as a devil and burning up the catwalk.
Tonight's fourth and final heat at The Cube Hotel will decide the last three finalists before the final showdown on Saturday, May 25.
All competitors are competing for the chance to be featured in the Zoo Weekly swimsuit calendar.
The national winner will be announced after the world finals event, which will be held in the Bahamas later this year.
