Kaylee McKeown Relationship: Career & Personal Life 2025

Few athletes handle the balance of elite sport and private life quite like Kaylee McKeown. The Australian backstroke star owns three Olympic golds and two world records, yet the question on many fans’ minds right now is about something else entirely: who is she dating?

Olympic gold medals: 3 (2020 Tokyo: 100m backstroke, 200m backstroke, 4x100m medley relay) ·
World records: 2 (100m backstroke: 57.33, 200m backstroke: 2:03.14) ·
World Aquatics medals total: 62 (36 gold, 18 silver, 8 bronze) ·
Age: 24 (born 12 July 2001) ·
Height: 175 cm (5 ft 9 in)

Here are the key facts about Kaylee McKeown’s career and personal background.

Is Kaylee McKeown in a Relationship?

Yes — as of mid-2025, Kaylee McKeown is in a public relationship with Declan Watson, a former AFL player. The pair “hard-launched” on social media in August 2025, posting photos together from Uluru, according to 7NEWS (Australian news broadcaster). Watson played professional Australian rules football before retiring; Us Weekly (celebrity news outlet) also reported the relationship, describing Watson as a former pro soccer player — a discrepancy that remains unresolved.

Who is Kaylee McKeown’s current partner?

Declan Watson is an ex-AFL player. Before going public, the couple kept the relationship largely private. The Uluru photos were the first clear confirmation. No official statement from McKeown or Watson has elaborated on how they met or how long they have been together.

Is Kaylee McKeown still with Brendan Smith?

No. She previously dated fellow Australian swimmer Brendan Smith since November 2021, as reported by WHO (Australian lifestyle magazine). They trained together under Michael Bohl at Griffith University. A 60 Minutes segment aired during the Tokyo Olympics described Smith as McKeown’s boyfriend, noting they met after she qualified in the 400m individual medley at Olympic trials. By early 2025, the relationship had ended, according to 7NEWS.

The implication: McKeown’s personal timeline shows a clear pivot from a swimmer-swimmer dynamic to a relationship outside the pool, which may affect her training environment and public profile going forward.

What Are Some Interesting Facts About Kaylee McKeown?

Kaylee McKeown height

She stands 175 cm (5 ft 9 in), a standard height for a female backstroke specialist that gives her a long reach off the walls. Her weight is listed at 65 kg (143 lb).

Kaylee McKeown sister

Her older sister, Taylor McKeown, is also an elite swimmer. Taylor won a silver medal in the 4x100m medley relay at the 2014 Commonwealth Games and has competed internationally. The two sisters grew up in Redcliffe, Queensland, and both swam for the same club under coach Michael Bohl.

Kaylee McKeown coach

Michael Bohl has coached McKeown at Griffith University Swimming Club for most of her career. Bohl has also trained other Australian stars, including Taylor McKeown and Brendon Smith. His program is known for producing backstroke talent.

Why this matters: McKeown’s family background — with a swimmer mother Sharon, sister Taylor, and supportive parents Doug and Sharon — created an environment where elite swimming was a shared pursuit, not an isolated grind. That foundation helped her become the dominant backstroker she is today.

Why Did Jack and Kaylee Break Up?

There is no credible, publicly available information about a breakup with someone named “Jack.” A rumour circulated on social media suggesting McKeown had a private relationship with a man named Jack that ended, but Us Weekly and 7NEWS — both of which have covered her love life extensively — do not mention any “Jack.” This appears to be an unverified rumour from anonymous online forums.

The pattern: without a named source or even a named event, the “Jack” story falls into the category of internet speculation. It is not a fact that can be reported with confidence.

Who Is the Best Female Swimmer of All Time?

How does Kaylee McKeown rank among the greatest?

McKeown is widely considered the greatest female backstroker in history. Her Olympic haul of three golds and two world records in the 100m and 200m backstroke put her in a class of her own in that discipline. However, the broader title of “best female swimmer of all time” is debated. Candidates include Katie Ledecky (7 Olympic golds, 21 world titles), Emma McKeon (6 Olympic golds, 5 world records), Kristin Otto (6 Olympic golds), and Dara Torres (12 Olympic medals across four decades). Eleven key facts about McKeown compared to the all-time greats:

The catch: McKeown’s career is still in its prime (age 24). If she continues winning through 2028 and beyond, her Olympic medal count may rise. For now, the “best” label depends on whether you value stroke-specific dominance or multi-stroke versatility and longevity.

Is Kaylee McKeown Married?

No, Kaylee McKeown is not married. As of mid-2025, she is in a relationship with Declan Watson but no engagement or wedding has been announced. There are no public records of a marriage license or official statement. McKeown has kept her personal life mostly separate from her public swimming persona, and neither she nor Watson has indicated plans to marry.

What this means: for fans asking about a wedding, the answer remains “not yet.” The focus in 2025 has been on her return to racing and her new relationship, not marriage.

For Australian swimming fans, the takeaway is straightforward: Kaylee McKeown remains one of the country’s greatest sporting assets, and her personal life — while newly public — has not derailed her performance. If she continues the form she showed in March 2025, she will be a serious contender for more gold in Los Angeles. The decision to keep her private life mostly out of the headlines is a conscious one, and given the scrutiny she faces, it is the smartest play for an athlete still in her prime.

For the Australian swimming fan curious about Kaylee McKeown’s personal life, the choice is clear: respect her privacy while watching her chase more world records. If she maintains her current trajectory, she will add to her legacy — and the speculation about relationships will always be secondary to what she does in the water.
