The annual national day of support held last month gets bigger and bigger every year, according to Blue Light Appeal chief executive Mark Leach.
The Mediforce founder said WA relied on volunteers such as those with the SES.
Emergency Services minister Joe Francis said WOW Day was an opportunity for people to honour the hard work and dedication of emergency service volunteers.

Elizabeth Quay and Council House were among landmarks that were lit up in orange to mark WOW Day.
Mr Leach launched Blue Light Appeal last year to raise money and awareness for emergency service personnel who suffer from post-traumatic stress disorder and their families.
The inaugural fundraising event is on Saturday, July 16, at Government House Ballroom.
Money raised will go towards bringing a NSW document about the signs, symptoms and remedies for PTSD to WA for training purposes as well as to be distributed among charities doing research on PTSD.
Mr Leach spent eight years in the military before doing stints in the police force and as a firefighter and paramedic.
He was diagnosed with PTSD 10 years ago and “it took three years to get on top of it”.
“You are never cured but you learn the skills to deal and cope with it,” Mr Leach said.
