When Mark Guillaumer bought his dream car in 2019 his brother Dan thought he had a lot of looking forward to do.
But Mark, who suffered mental illness for years, took his own life less than one week later.
Mr Guillaumer, who lives in Warrnambool, now sees his brother's beloved orange fury Mustang as a reminder of the importance of having an open conversation about mental health.
"The mustang is a good reminder that despite the appearance of a happy mask that people might put on, it's still important to reach out," he said.
"For me, the Mustang is a reminder of something that made (Mark) really happy. We all thought he was doing really well, he had a lot of looking forward to do which I thought would really assist him as he struggled with mental health for a long time."
Mr Guillaumer is completing 3318 push-ups this month to help promote awareness and encourage positive mental health.
The number of push-ups reflect those who committed suicide in Australia two years earlier.
The Push-Up Challenge is a nation-wide event that raises funds for a charity of choice.
In less than a week, Mr Guillaumer and his 20-person team, titled 'Orange Fury Mustang', have raised nearly $6000 for Lifeline Australia.
He said he first joined the challenge back in 2019 after his brother attempted suicide.
"Mark narrowly missed being a statistic and one of the push-ups for this year," he said.
"I joined the Push-Up Challenge back then as a show of support for my brother. Unfortunately a month after that first challenge, he passed away."
Mr Guillaumer said his team was made up of 20 family members and friends, including eight people from the south-west.
He said each person had to complete the 3318 push-ups.
"It's such a big target and I see it as a bit of an analogy for the struggle of mental health," Mr Guillaumer said.
"It seems unachievable, like you'll never get over it or it's just too hard to deal with but that's where the team aspect comes in as we all support each other.
"I think that shows that mental health is easier to overcome with support rather than struggling on your own."
The Push-Up Challenge runs for the month of June.
