Police, Ambulance, SES, Forrest Fire Management and CFA representatives were on hand to talk to students and showcase some of the work they perform out in the community.

From rides on the ambulance bed to sitting in the SES rescue boat, let's not forget about piling into the back of a Police 'divvy van.

Year 12 VCAL student Myles Gellie organised the expo and he wanted to highlight the impacts of PTSD in emergency services as part of a topic for one of his VCAL assessments.

Organising an expo stemmed from a presentation he created for his peers.

Mr Gellie, a volunteer firefighter himself, said at the beginning of his presentation students weren't overly interested in the impacts of PTSD within the emergency service sector.

"Originally I only started with one or two services coming to school," he said.

"From there it just grew and we managed to get most here.

"From doing my research I was so surprised how unaware people are about the impacts of PTSD within the sector."

Mr Gellie hoped the expo creates awareness and put to rest some of the barriers that surround emergency services.

"I hope it starts a long appreciation from the students of our emergency services and just what they do each day for the community," he said. "It's not just for the students - I hope the emergency crews that attended have a great time and could be a boost for their mental health as well."

Mr Gellie started as a volunteer firefighter through his cousin who is the captain of the Great Western fire brigade.

"I originally starting out doing the fire brigade running and it grew from there," he said.

"I saw what you can do and honestly, it's the best decision I've made in my life."

Principal Carlos Lopez said the school had been working hard to connect its VCAL students to the community.

"I think that has some major outcomes with their results and make those connections," he said,

"I think Myles has done a fantastic job making sure combining both community and school.

"By linking services like Police, which some students can be a bit apprehensive towards is a fantastic initiative.

"We've done some great work with Police through our breakfast program and today (Wednesday) is just another showcase of how we're working together to break down a few barriers some students might have."
