Mia Scerri

Mia Scerri, who has competed in athletics for 15-years, has compiled one of the most impressive junior athletics careers, including winning three consecutive Australian U20 heptathlon titles. Transitioning beautifully out of the juniors, she has quickly evolved into one of Australia’s best senior heptathletes. The now 21-year-old claimed the 2026 Australian heptathlon title and is selected for the Commonwealth Games – her fourth Australian team.

It was an early start in athletics form Mia when she was aged five, alongside her older sister at Sandringham Little Athletics. “I competed in my first state combined event competition when I was eight years old and have always enjoyed the unique camaraderie between competitors, where we push each other to perform at our best while supporting one another.”

Through her teenage years, in addition to winning numerous State and National combined event titles, Mia has always been strong in individual events. When she was 14 she won an Australian long jump title and other Australian medals in high jump and the 400m. Shot put has also been one of her finest individual events.

After the COVID effected 2020 year where she had very limited competition opportunities, she made the most of the next competition window mid-COVID in early 2021 – agreeability a breakthrough three months in her career. Aged 15, in two heptathlon competitions, the Victorian and Australian Championships she scored excellent scores of 5435 and 5553 points with the under-18 specifications. At the Australian championships event she won by nearly 1000 points. Individually she set PBs across the board highlighted by 6.09m in the long jump and 14.56m (3kg) in the shot.

Coming out of the Victorian COVID restrictions, in early 2022 Mia was in pursuit of qualification for the World U20 Championships – 5300 points in the heptathlon and 6.12m in the long jump. That summer she was aged 16/17 and came incredibly close to qualification before the team was selected in April 2022. In the long jump she would record competitions of 6.08m, 6.07m, 6.04m, 6.03m, 6.08m and 6.01m. She would also surpass the standard (6.12m) with windy jumps of 6.14w and 6.12w (2.1m/s !!). In the Heptathlon she achieved scores of 5226, 5000 and 5292, but alas would fall short by 8 points, equal to 2cm in the long jump or half a second in the 800m.

Months ahead of the 2022 World U20 Championships were to be held in August, competing at the Oceania Championships in June, Mia scored 5480 points – a massive 180 points over the standard.

During Mia’s 2022/23 summer campaign she tallied heptathlon scores of 5410, 5311 and 5537, winning her second Australian junior title. The long jump had taken off as she leapt 6.27m. Selected for the World University Games, she would place 12th with a terrific score of 5531. Three months later in November she would win the Pacific Games heptathlon with a PB score of 5624 points. During the year her high jump and shot put had really improved. She added 7cm to her HJ (1.77m) and over a metre to her shot (13.70m).

After missing the 2022 World U20 Championships, in 2024 Mia would have a chance at competing at the 2024 World Juniors, but the year was hampered by injury. Off just a few competitions in early 2024, at the World U20 trials Mia would win her third Australian U20 Heptathlon title with a tally of 5429 points. Still hindered by injury she would go on to place a magnificent fourth at the World U20 Championships with a score of 5550 points. “The biggest challenge I have faced was coming back from injury before competing at the World U20 Championships and having to complete modified training leading up to the championships.”

In 2025, Mia’s first season as a senior, she pushed her PB score up to 5770 at the Australian Championships and placed 9th at the World University Games in Germany. Individually every event was improving or becoming more consistent. It seemed to set her up for her next big breakthrough in 2026. In January she added 149 points to her heptathlon PB scoring 5919, then at the National Championships, against the best heptathlon field assembled in the history of the championships she added 256 points and won the National title. During the Australian championship performance, she sets PBS in six of her events, only missed a PB in the 800m – by half a second. In June she was named on the Australian team for the Commonwealth Games.

In 2026 Mia reflected on some advice to her younger self: “Be patient and trust the process.” Certainly, through her career she has had to follow that advice from her wiser self.
