She completed her first responder training and loved being a volunteer so much she underwent further training.
Nicole recently completed her national diploma in ambulance practice, qualifying as an emergency medical technician (EMT).
In her volunteering role she is out on the road with a paid ambulance officer once a fortnight, spending around 12 to 14 hours helping those in her community.
"It's challenging, exciting and rewarding," she says.
Not long after she started her volunteer training, Nicole saw an advert for a fulltime first aid training administrator role at St John.
Her application was successful and Nicole is one of 40 per cent of St John employees who also volunteer in their spare time.
"I wanted to get the satisfaction of giving back to my community and helping people," she recalls.
"Since furthering my clinical skills and knowledge, I am now able to support my crew partner more effectively.
"It's such a rewarding feeling after successfully treating a patient and I think wow, we made a difference to that person's life."
Nicole says people who are unsure about whether they should volunteer should just do it.
"You won't regret it. It's so amazing for personal and professional growth. It's totally worth it."
