After they each won a Colombo Plan Scholarship to study in Australia, they began, in 1964, their medical courses at Monash.
Siew-Har was first, bonding with chemistry partner Boon Low “fighting over experiments” in the lab. “He was very neat and I was a bit untidy,” she explains. But the opposites attracted.
In her second year, Siew-Hoon met Leong Lim “over a cadaver”, she says with a laugh.
He had transferred to medicine from science, and at lunchtime they would stay back in the anatomy lab to perfect their dissections.
“We were nerds,” Siew-Har says. And that strong work ethic saw the twins graduate equal-third in their year. “People said we were telepathic, that we would each study half the text and read each other’s minds, but I wish! Really, we just studied together,” she says.
“Every night without fail,” Siew-Hoon says.
The twins were boarding with a Scottish couple with whom they became lifelong friends, and while they studied they were also getting to know their future husbands. Money was scarce, so courtship was simple. Shared coffees progressed to lunch, then long walks through the Royal Botanic Gardens, movies and lots of talking. “We hung around together back then, and we’re still hanging around now,” says Siew-Har.
“Over 50 years later,” adds Siew-Hoon.
After their final exams, and before graduation, Siew-Har and Boon married. Held at a city Chinese restaurant, and without parents, their wedding served as a huge celebration for the 1964 graduating class. “We had a ball. It was like a big medical party,” says Siew-Har. “Everyone had such a good time. We asked three different friends to take photos, and none of them came out. None! I think they were drinking too much to load the camera properly.”
That cohort has remained close, and reunited last year for the 50th anniversary of their graduation – the twins organising fundraising for a scholarship on their behalf. “We got to where we are on scholarships, so I always say, ‘We have got to give back, because it makes a difference to somebody’s life’,” Siew-Har says.
Their Monash education taught them how to think and how to question as well. “It was a young university full of ideas,” Siew-Hoon says.
“But there was a lot of mud. I had to buy my first pair of boots,” Siew-Har says.
Under the terms of their scholarships, the twins and their partners returned to Malaysia, where Siew-Hoon and Leong were married. Both couples began their careers, and each had two children, but when the Whitlam government brought a legal end to the White Australia (immigration) policy, they returned to Australia, to their friends, freedoms, and a country they loved – even if the lack of ‘home help’ and childcare took some getting used to.
After subsequently running Eildon hospital in country Victoria, the couples settled a few streets away from each other in Melbourne’s east, establishing their own general practices in adjacent suburbs. Their patients, says Siew-Har, sometimes confuse them in the street. “They say, ‘Which Dr Cheah are you?’, and I say, ‘Well, which Dr Cheah do you attend?’.”
Their children, also all Monash graduates and now working in medicine and finance, grew up together – more like siblings than cousins, sharing one babysitter between them.
Now in their 70s, the twins are as close as ever, continuing to practise tai chi together while juggling grandchildren with paid and volunteer work. Siew-Har and Boon still work at their clinic, while Siew-Hoon volunteers at Camcare, helping vulnerable people navigate daily life.
Their husbands, too, also still get along. “One cooks and one eats,” they say with a laugh. “So they are a good combination.”
