Melissa McShane, Charlotte Midson and Sarah Elias' proposal to rejuvenate the town centre as "Poppins Plaza" has captured the imagination of the Bowral Chamber of Commerce and Industry.

The girls' plan, developed for a competition run by Mittagong architects Allman Johnston, includes a chiming clock tower linked to a musical fountain, a Mary Poppins statue and kites flown from graphite rods.

In a presentation to chamber members on Monday, Melissa, Charlotte and Sarah said Bowral could be considered the birthplace of Mary Poppins

Pamela Lyndon Travers lived in Bowral from 1907 to 1918, and town is thought to have inspired at least four of the major characters in her book.

Bowral is the only one of P.L. Travers' four Australian homes that does not publicly recognise its famous former resident.

"Bowral is the missing link," said Melissa.

Melissa said P.L. Travers' name was known throughout the world as a result of her books and the Disney movie. A Cameron Mackintosh musical soon to open in London's West End would boost interest in Mary Poppins even more, she said.

Melissa, Charlotte and Sarah visited sculpture parks and interviewed Corbett Plaza business owners and P.L. Travers' biographer Valerie Lawson while researching their "Poppins Plaza" plan.

The proposal also includes a Bowral Walk of Fame, levelling and repaving of the plaza, an etched Perspex screen and gazebos to shield the plaza from the weather and replacing the liquid ambers with more appropriate species such as claret ash.

"(Corbett Plaza) is not really a good enough centrepiece for our town the way it is now," said Melissa. "There is no interesting theme or structures."

"It's boring," said all the girls.

Chamber members were enthusiastic about the potential of the proposal to boost tourism as well as rejuvenating Corbett Plaza.

"This is the most refreshing, genuinely innovative idea I have heard for a long time," said chamber committee member Malcolm Yell. "It puts to shame the dowdy old view most people have of Bowral."
