There is a plumber in Ryde, NSW who recently discovered he had overcharged a customer by five dollars. He didn’t tell himself it wasn’t worth the effort. He went back through his records, confirmed the discrepancy, and issued the refund. That is who Alex Taskun is now. But to understand why a five-dollar refund matters to this particular man — you need to know where he’s been.

In April 2004, Alex Taskun was a 27-year-old business development manager from Lidcombe, walking near Auburn Railway Station. He came across a man being stabbed — not threatened, not confronted, but already stabbed multiple times. The attacker had slashed his chest, then driven the knife into his abdomen.

Alex didn’t calculate the odds. He chased the attacker down, tackled him, disarmed him, bagged the knife as evidence, directed bystanders, managed traffic, and administered first aid until help arrived. That was it. That was the whole decision, made in a second.

For that act, Alex received four official honours: the Star of Courage from the Governor-General of Australia — the nation’s second-highest civilian bravery decoration, held by fewer than 165 people in history — and on the day of the ceremony, he was the sole Star of Courage recipient among the 35 Australians honoured. He also received the Royal Humane Society of NSW’s Silver Medal, their Galleghan Award for the single most outstanding act of bravery in NSW that year, and — as a consequence of the Galleghan nomination — the Stanhope Gold Medal from the Royal Humane Society of the United Kingdom, awarded annually since 1873 for the bravest rescue across all participating nations worldwide. Alex is one of only 12 recipients from NSW since 1962.

He accepted the recognition graciously and went back to work. But something had been confirmed inside him — a sense that had always been there — that when someone needed help, you did not look away. You could not. Not if you were the kind of person he intended to be.

A few years later, he bought a ticket to Cambodia.

What drew him there, Alex says, is “a very beautiful dream — I’d like to keep that personal.” Cambodia wasn’t Australian. It wasn’t Muslim, wasn’t Christian, had little or nothing to do with the Western world he knew. He had no connection to the country, no heritage there, no contacts. He had no knowledge, at the time, of Pol Pot or the Khmer Rouge or the Killing Fields. He learned that along the way.

Something drew him there. He can’t fully explain it. He went.

It took about six hours to drive from Phnom Penh to the first village. No electricity. No running water. People living in conditions that, by any Western measure, constituted severe poverty.

They were smiling.

He had arrived, as most well-meaning Westerners do, with an assumption baked in: that he would bring people up to the same standard of living, education, and happiness that he thought he understood. That he could help them by closing the gap between their world and his. He came to realise that this impulse — generous as it was — was itself a kind of indoctrination. A presumption that he had something they were missing.

What he eventually learned was that there is a profound difference between being happy and being content. He had arrived in that village and misread their contentment as unhappiness. And in doing so, he’d almost missed what they had to teach him. Seven to ten years of hard lessons later, he understood exactly why the universe had called him there — and it wasn’t to deliver Western standards. It was to sit with people who had survived the unsurvivable, and to give them something specific: food, education, medicine, and the knowledge that someone far away had seen them and decided they mattered.

What Alex found in Cambodia was extraordinary. What he also found was corruption so pervasive and systematic that it ran through almost every transaction, every negotiation, every handshake at every level of government and civil society.

“There is a corrupted black book,” he explains. “A book where people use bribes, cash money, and corruption. When I did my work, I never engaged with this. I refused.”

Coming from a banking background — credit analysis, anti-fraud work, governance — Alex had an unusual ability to see exactly how the system operated. He could see how invoices could be fabricated out of thin air. He understood immediately what checks and balances were absent and why. He could read the machinery of it clearly, which made it all the more painful to navigate.

He waited instead. Eight weeks, ten weeks, twelve weeks — sometimes many months — for documentation that could have been expedited with a two-hundred-dollar note. He refused every time.

The results were predictable in the short term. Projects stalled. A water well program — designed to provide clean water to communities still poisoned by Agent Orange dioxin that had leached into the water table decades after the war — was blocked entirely because he wouldn’t pay. They were pushed aside. The green light never came.

He went to the Minister Against Corruption for help navigating the legal system. By the third meeting, the minister had made his position clear: he wanted a role in the organisation, a salary, a percentage. He saw an Australian flag and saw dollars.

Alex’s response was characteristically direct: cut out the middleman entirely. No ministerial photos on the banners. No governors invited to the table. No power brokers. He went directly to the source — to the people themselves — and built his own team from the ground up, vetted person by person, tested through small acts of trust before being given larger ones.

He developed a system for every distribution. Two separate teams. The first would do exhaustive on-the-ground research: who was in need, what village, what circumstances. The second would handle the distribution itself. Every recipient received a numbered card. Photos were taken. Four points of verification, four people signing off on every handout. “Inspect what you expect,” he says. It became the guiding principle of everything he did.

When a village chief once refused access to poor families in his community because those families hadn’t voted for the right party, Alex didn’t fight. He invited them to travel to a different location to collect their food instead. “It’s like chess,” he says. “You’ve got a stack of cards in your favour. Make the chessboard work for you.”

That day, sixty people had enough food for four to six months.

He attributes much of this strategic thinking to his dyslexia. A mind that struggled with words had learned to navigate differently — to see systems whole, to find the move three steps ahead of the obvious one.

Among everything Alex built in Cambodia — the million-plus meals to orphans, genocide survivors, and the rural poor; the rice farms and cattle purchased to ensure ongoing food supply; the children’s hospital visits alongside local monks and friends from the international language school; the food, clothing, and nappies handed to families who had nothing; the $25,000 to $50,000 spent on dental care programs, negotiated through a formal memorandum of understanding between organisations because he knew how to structure things properly — among all of it, one program stands apart.

He had an idea. In villages with no electricity and no running water, where children of genocide survivors grew up in conditions the rest of the world had forgotten about, there were brilliant minds. He was certain of it. The question was how to find them.

He wrote pattern recognition questions on the walls of mosques and temples. MENSA-standard tests, adapted for the environment. He targeted children between the ages of eight and eleven.

He found four girls.

One is completing a master’s degree on her way to becoming an English teacher. Two others have graduated from university and are building careers in their fields. And one — the one that stops you mid-sentence when Alex mentions her — completed her medical degree overseas and is now preparing to come to Australia for specialist training. She wants to be a surgeon. Possibly an obstetrician. She intends to return to somewhere in the world where a world-class obstetrician can change and save lives.

She was a girl in a village with no electricity. She answered questions written on a mosque wall.

Others from the broader scholarship programs are now senior managers at firms like ExxonMobil and major consultancies. These people were eighteen years old in the early 2010s. They are thirty now. The arc of their lives bent, at a crucial moment, because one Australian refused to walk past.

The organisation operated on a principle that was, in the Australian charitable landscape, essentially without precedent: zero percent administration costs. One hundred percent of every dollar donated went directly to the people it was intended for. The books were open. Audited. Documented. After fourteen-hour working days, Alex would spend the final two hours uploading footage and content so that donors could see exactly where their money had gone. Every promise tracked. Every commitment honoured.

“One hundred percent for the needy. Zero percent for the greedy.”

His community voted him Man of the Year.

Then the rumours started. He won’t go into detail. He won’t name names. What he will say is that he took no heat to it. “It means nothing,” he says. “Because on the ground, I knew what I was doing and how I was changing people’s lives.” He is still proud of what that community built. He is still proud of the movement it created.

In 2017, Alex’s father was diagnosed with cancer.

Many people drive a parent to palliative care. They visit. They sit beside the bed. They go home. Alex stayed.

He fed his father. He bathed him. He showered him. He was there through the whole of it — through the decline, through the indignity, through the end.

When his father died, Alex washed his body himself. By hand. On a cold, stainless steel washing block. And then he buried him.

There is nothing to add to that. It is its own testimony.

After everything — the bravery award, seven years in Cambodia, his father’s death, the betrayals — Alex Taskun became a plumber.

It sounds like a step down from everything that preceded it. It isn’t.

“Plumbing is where you can change people’s lives,” he says. “When people don’t have hot water, a broken pipe, a blocked sewer, no gas, no cooking — they want that inconvenience sorted out. It’s like being an ambulance or a fire brigade officer.”

He built GT Plumbing from nothing. Over two hundred five-star Google reviews. Long-standing relationships with Raine & Horne, McGrath, LJ Hooker, and Ray White, who trust him with their properties and their clients. Customers who have been with him for a decade. Customers who leave their keys for him when they travel. Customers who remember his birthday.

He recently went back and gave a customer a five-dollar refund. He’d found an overcharge when reviewing his records. He fixed it. He’s also had customers doing it tough and told them to keep five or six hundred dollars because it wouldn’t make him rich and it might make a real difference to them.

The same instinct that refused to open the black book in Cambodia. The same instinct that chased a man with a knife on an ordinary afternoon in Auburn because someone was in trouble and he couldn’t not act.

Ask Alex Taskun who he is, and he doesn’t reach for the medals. He doesn’t mention Cambodia first. He doesn’t lead with the father he buried or the lives he changed or the betrayals he outlasted.

He says: someone who’s still learning every day.

A veteran, yes. Someone who can see through dishonesty in seconds, who trusts his gut completely, whose gut has never once told him to give up. Someone who understands that people are not perfect — including himself, he’s quick to say. Someone who has seen corruption from the highest levels of government, across judicial systems, through charitable organisations, through the small daily acts of people who have decided that cutting corners is just how things work. And someone who has decided, in full knowledge of all of that, to be kind.

“I need to provide that kindness in this world,” he says. “Because this world is full of cowboys and dickheads.”

He is not wrong. And he is not finished. The next chapter is already taking shape — a return to humanitarian work in Indonesia, built on everything he learned in Cambodia and everything he refuses to repeat.

The universe, it seems, is not done with Alex Taskun.

And he is not done with it.
