The morning of Saturday, May 17, 2026, dawned bright and inviting over Rottnest Island. Turquoise waters lapped gently against Horseshoe Reef, just one kilometer offshore, promising another rewarding day for those who knew how to read the ocean’s moods. Steven “Mattas” Mattaboni, 38, kissed his wife Shirene and their two little girls goodbye with a grin. “Daddy’s bringing home dinner tonight,” he told them. “Wait for me.” Those words, spoken so casually, would become the final promise that now haunts everyone who loved him.

Steven and three close friends had set out for a spearfishing session they had done many times before. Experienced, cautious, and deeply respectful of the sea, the group anchored near the reef’s edge where visibility was excellent and fish were plentiful. What unfolded in the next few minutes would leave two of those friends forever changed, their voices cracking as they later recounted the horror to investigators and loved ones.

“We were all on the surface, maybe 20 meters from the boat,” one friend, speaking on condition of anonymity, described in the days that followed. “Mattas was right there with us, strong and focused as always. Then it just came up like a freight train from the deeper side. No warning shadow, no time to react. The great white hit him hard on the lower legs. The water exploded around him.”

In an instant, the crystal-clear blue turned a visceral, shocking red. Blood clouded everything as the estimated 4- to 5-meter shark thrashed with terrifying power. Steven fought desperately. Witnesses say he surged upward, breaking the surface in a burst of foam and crimson, gasping for air and screaming for help. His arms flailed, his voice carrying across the water in raw panic. “Help! Help me!” — the cries still echo in his friends’ nightmares.

But the distance, even if only 20 meters, proved too far in those critical seconds. The second friend, fighting back tears during a private recounting, continued: “We swam as hard as we could, yelling his name. The water was so thick with blood it was like swimming through paint. By the time we reached him, the shark had released and circled once before disappearing into the depths. Mattas was still conscious for those first moments, but the injuries were catastrophic. We dragged him onto the boat, tied tourniquets as best we could, and started CPR while racing full throttle toward Geordie Bay Jetty.”

The boat cut through the waves at maximum speed, one friend steering while the other two worked frantically on their bleeding companion. Blood pooled on the deck. Steven’s pulse faded under their hands despite their relentless efforts. Paramedics and police were waiting at the jetty. They took over immediately, performing CPR for more than 30 minutes while a rescue helicopter hovered overhead. It wasn’t enough. Steven Mattaboni was pronounced dead at the scene, Western Australia’s first fatal shark attack of 2026.

The Friends’ Haunting Recollection

The two friends who were closest to Steven during the attack have not spoken publicly by name, respecting the family’s privacy. But in conversations with authorities and close circles, their accounts paint a vivid, gut-wrenching picture of those final moments.

“One minute we were joking about who would get the biggest fish,” the first friend recalled. “The next, the ocean turned red and Mattas was fighting for his life right in front of us. He broke the surface twice, eyes wide, calling out. We were screaming back, swimming harder than we ever have, but the current and the blood… it felt like slow motion. We got to him, but the damage was already done. That image — his face coming up through the red water — will stay with me forever.”

The second friend added details that underscore both the speed and the brutality: “The shark was massive, easily over 4 meters, a mature great white. It hit with such force that it shook the water around all of us. Steven tried so hard to get to the surface and reach us. His last efforts were pure survival instinct and the will to get back to his girls. We pulled him out, but he had lost so much blood. On the boat ride in, we kept talking to him — ‘Stay with us, mate. Think of Shirene and the kids.’ He slipped away before we made it to shore.”

Their voices break when they mention the promise Steven made that morning. They knew how excited he was to get home with fresh catch. “He always provided,” one said. “That was his thing — being there for his family.”

Shirene’s World Collapses

Back in Perth, Shirene Mattaboni, a clinical nurse specialist at Royal Perth Hospital, was preparing for a relaxed family afternoon. She had received Steven’s last message — a photo of the calm sea and the words promising an early return with dinner. She showed it to their toddler, smiling: “Daddy’s bringing home something special tonight.”

When the knock came and the news was delivered, Shirene’s strength as a nurse could not shield her from the devastation. She collapsed, clutching their four-month-old while their almost-three-year-old kept asking for Daddy. In the raw grief that followed, she shared the words that have since broken hearts worldwide: the simple, loving promise that now feels like a cruel twist of fate.

In her public statement the next day, Shirene wrote with heartbreaking dignity: “Our hearts are irrevocably broken by the loss of Steven, known affectionately to his mates as ‘Mattas.’ Steven was a devoted father to our two beautiful daughters — one who turns three next month and our four-month-old baby. An avid fisherman and spearfisherman who lived and breathed the ocean, he was always in tune with the sea. He was fiercely loyal, endlessly generous, and the kind of man who would give you the shirt off his back. The world has lost a truly one-of-a-kind gentleman, and our daughters have lost an incredible father far too soon.”

Yet it is the private echoes of “Daddy’s bringing home dinner tonight. Wait for me” that friends say cut deepest. Shirene has been seen sitting by the window in the evenings, staring at the empty driveway, whispering those words back into the silence.

A Life Built on the Water

Steven Mattaboni was more than a victim of a tragic encounter. He was a surveyor by profession but lived for the ocean. As secretary of the Bluewater Freedivers WA club, he mentored others, promoted safe practices, and found peace beneath the waves. His friends remember him as the steady one — the guy who checked everyone’s gear, shared his knowledge freely, and always made sure the group got home safely.

On the football field with Kingsley club, he was a premiership player whose smile lit up the rooms. At home, he was the dad who sang silly songs at bedtime, carried his toddler on his shoulders during beach walks, and supported Shirene through her demanding shifts. The family photos now circulating show a man radiant with quiet joy: cradling his newborn by the sea, teaching his eldest to fish, embracing Shirene with the easy affection of true partnership.

The ocean gave him so much — freedom, provision, serenity. On that Saturday, it took everything in return.

The Aftermath and a Community in Mourning

News of the attack spread rapidly across Western Australia and beyond. Premier Roger Cook, Police Minister Reece Whitby, and countless community groups offered condolences. Steven’s football club posted tributes highlighting his character. Spear fishing communities shared stories of his generosity and called for continued respect for the ocean’s power.

On social media, the story ignited an outpouring of grief. Thousands shared the family images, lit virtual candles, and quoted Shirene’s words. Parents hugged their children tighter. Ocean enthusiasts debated safety measures — more drone surveillance, better education, drum lines in high-risk areas — while acknowledging that Steven and his friends were experienced and responsible.

Rottnest Island, a beloved tourist destination with its quokkas and pristine beaches, issued heightened warnings around Horseshoe Reef and Geordie Bay. The area remains open but with strong cautions. Coronial inquiries continue, and experts note the role of environmental factors in bringing great whites closer to popular spots.

For the two friends who witnessed everything, the trauma runs deep. They have supported each other and the family, but the images of red water and Steven’s desperate struggle to surface haunt their waking hours. One confided quietly: “We did everything we could. We got to him as fast as humanly possible. But the ocean decided differently that day.”

A Promise That Lives On

As funeral plans take shape, Shirene has requested privacy to focus on her daughters. She wants them to grow up knowing their father not as a headline, but as the loving, adventurous man who promised them dinner and meant every word. She envisions telling them stories of his dives, his laughter, his unwavering devotion.

In the quiet nights ahead, the family will gather strength from memories. The toddler may still bring her toy boat to the door, waiting. The baby will one day learn about the dad whose last thoughts were of getting home to them. Shirene will carry the weight of widowhood with the resilience of a nurse who has seen too much pain, yet none so personal.

The ocean that Steven loved so deeply claimed him in its raw power. But the promise he made that bright Saturday morning — “Daddy’s bringing home dinner tonight. Wait for me” — transcends the tragedy. It lives in the way his friends honor his memory, in the community’s renewed respect for the sea, and in the unbreakable bond of a family determined to heal.

Steven Mattaboni’s story is a stark reminder of life’s fragility. One moment you’re planning dinner with fresh catch; the next, friends are fighting through blood-red water to save you. It urges us to cherish ordinary promises, everyday goodbyes, and the precious time we have with those we love.

Though he cannot walk through the door with that promised dinner, Steven’s spirit sails on — in the waves off Rottnest, in the laughter of his girls, and in the enduring love of a wife who still waits, heart shattered but soul steadfast, for the man who always tried to come home.
