Skyla, now 14 months, made a full recovery but the experience hit home for the new North Fremantle parents.
‘When you have your own children, there’s more important things you want to be involved in,’ Mrs Wyllie said.
For the Wyllies, that means supporting Emily and Rick Parish to raise money for sick children through The Telethon Adventurers.
Their son Elliot died of brain cancer aged four, two-and-a-half years ago.
Next week, Mrs Wyllie’s engagement dress by Rachel Gilbert and the custom-made Celestial Tenielle piece she wore to the 2009 film premiere of Two Fists One Heart will be on sale at the Red Herring. It is among other donated clothes that will be sold to raise money for the charity.
Lord Mayor Lisa Scaffidi, children’s author Gretel Killeen and designer Aurelio Costarella are among other A-listers who have donated dresses.
Organiser Narelle Antonio, a mother of three, said she helped host the inaugural Spring Soiree cocktail party that involved runway fashion by designers for the Telethon Adventurers last year.
Mrs Antonio said she was intrigued by the fashion worn by Perth’s A-listers so had invited Perth’s well-known to become more involved this year.
Mrs Parish, who has sons Harrison (9) and Hudson (7), said she was amazed at how the WA community had embraced her family because there were so many charities.
‘When I stand at Elliot’s grave, it fires me up… I don’t want other mothers to have to stand there like me,’ she said.
‘We’ve raised $5 million so far but we need to keep going.
‘It’s not good enough that we can’t find the cause and cure for brain cancer.’
The Spring Soiree is on Wednesday, September 18 at the Red Herring in East Fremantle.
Tickets are $95, and include drinks and canapes.
