A 23-year-old Adelaide man has been killed in a motorcycle crash just two months before he was due to marry his Miss Universe finalist fiancée, leaving family, friends and the wider riding community devastated by the sudden loss.
Aidan Alchin, from Salisbury Heights, was riding his Yamaha motorcycle along Gorge Road at Paracombe when he collided with a Mitsubishi sedan and a Subaru sedan at around 12.50pm on Monday. He was pronounced dead at the scene. Both drivers walked away from the crash without injury.
Alchin had been planning to wed his partner of five years, Hayley Sutter, on December 12 in Hamilton, South Australia. Sutter, who competed as a South Australian state finalist in Miss Universe Australia in 2025, had shared numerous photos of the couple on her social media pages. As of Wednesday, the couple's wedding website was still counting down the days to their ceremony.
A life cut short before the aisle
The tragedy arrives with a particularly cruel timing. Alchin had already cheated serious misfortune once before — surviving a significant crash in 2021 that left him with injuries to his lower back. That incident changed the course of his life, prompting him to leave a career in construction and join his father's locksmith business.
Friends who knew him described a man of towering presence — both literally and figuratively. One close friend, Louis Parcel, remembered the "almost 7FT legend" as someone who would go out of his way for anyone around him.
"He was like our personal security guard every time we were filming in the city or out," Parcel said. "Seriously, this man would literally drop anything for you and have your back always. He was always wild but with a heart of absolute gold."
Another longtime friend struggled to put his grief into words, recalling shared birthdays, meals and years of laughter. "Words can't explain how much I miss you, bro," he wrote. "I'd give anything to have those days back."
Motorcycle community rallies in his memory
Alchin was a well-known and deeply respected figure in Adelaide's riding community. In a heartbreaking twist, he had been planning to participate this Friday in a memorial ride honouring a fellow motorcyclist who had recently passed away. That ride will now serve a dual purpose — celebrating both lives lost.
Riding group Two Wheel Turtles confirmed the change, posting a tribute to Alchin alongside their announcement. "As some of you are aware, yesterday we lost a mate and a brother," the group wrote. "Aidan was so welcoming to the bike community, great to have a yarn and a laugh with. Aidan's NGR ride would have been this Friday — let's get around this ride and make it the biggest, for Aidan. Ride eternally, Aidan."
Fellow rider Dylan Thorp said the loss was a stark reminder of the dangers every motorcyclist faces each time they head out on the road. "It's a heartbreaking reminder of just how quickly things can change when we're out on the road," he said, urging riders to check in on each other, ride within their limits and prioritise getting home safely. "The motorcycle community is a family, and today that family has lost one of its own."
Second fatality as SA Police renew road safety plea
Alchin's death was one of two road fatalities recorded across South Australia over the Labour Day long weekend. A 52-year-old man died in a separate, unrelated crash in Virginia at approximately 8.45pm on Sunday night.
SA Police Inspector Mark Atkinson said the two deaths over the holiday period had prompted a renewed call for all motorists to exercise greater care on the state's roads.
For those who loved Alchin, no road safety message can fill the void left behind — only the memories of a young man who, by all accounts, lived generously and loved fiercely, and who was weeks away from beginning the next chapter of his life.
