Australian broadcaster Nine identifies her full name as Jamie Lee Melham, née Kah. The reason for the switch is not a suspension, retirement, or illness; it is marriage. She married jockey Ben Melham, and race cards began listing her as J. Melham.

When did Jamie Kah change her name?

She married Ben Melham in January 2025, according to Reuters, and began using Melham as her race-name immediately.

The upshot: the name switch is a marriage, not a mystery — and the name on the race card will keep changing for the same person.

What is Jamie Kah doing now?

Jamie Kah is now riding under her married name Jamie Melham. She continues to compete in Australian and international races, with a full riding schedule according to Nine. She married fellow jockey Ben Melham in 2025 and won the Melbourne Cup that year.

Did Jamie Kah really win the 2025 Melbourne Cup?

Yes. New Zealand public broadcaster RNZ’s headline put it plainly: “Half Yours wins 2025 Melbourne Cup.” Nine’s coverage named the winning jockey as Jamie Melham. UK newspaper The Telegraph also used the Melham surname in its report.

  • 1995 — Born; Nine’s profile identifies her as Jamie Lee Melham, née Kah. Nine
  • 2025 — Marries Ben Melham and begins using the surname Melham. Reuters
  • 4 November 2025 — Wins the Melbourne Cup on Half Yours. RNZ
  • 2025 — Completes the Caulfield-Melbourne Cups double, reported by RNZ as a first for a female jockey. RNZ
Note: The name “Kah” did not disappear; it became “Melham.”

The upshot: yes, she won it. The victory was real; the name on the trophy just looked different.

Why is Jamie Kah not riding today?

She probably is riding. Race cards now list her under her married name, so searching for “Jamie Kah” can make her look absent even when she is in the jockey’s room. The better search term is “Melham.”

Nine’s post-Cup reporting describes her as an active jockey with a full riding schedule. The “not riding today” searches are the clearest sign of how quickly fans attach to a former surname. It is not that Kah has disappeared; it is that her official name has changed.

Tip: When searching for Jamie on race days, use “Melham” instead of “Kah”.

The better question: “Which name is on the race card?” For Jamie Lee Melham, the answer is usually the one you are not searching for.

What made the 2025 Melbourne Cup historic?

RNZ reported that the win gave Melham the Caulfield-Melbourne Cups double. According to RNZ, it was the first time a female jockey had completed that particular double. Nine added another layer: the 2025 Cup was also the first time a married couple raced against each other in the event.

That combination — a career-first victory, a women’s racing milestone, and a family-vs-family subplot — is why the 2025 race will be remembered long after the betting markets move on.

Why it matters: the 2025 Cup was both a debut win and a small piece of racing history.

What about Jamie Kah’s net worth, height and weight?

  • Net worth: no verified dollar figure appears in the reporting reviewed for this story. Coverage tends to link her earnings to prize money and sponsorship.
  • Height: her exact height is not listed in the major public profiles reviewed for this article.
  • Race weight: jockeys manage their weight for each meeting, and Melham’s current race weight is not a permanent public number.

The takeaway: do not confuse a missing figure with a real story. For jockeys, what matters is the race-day card.

What the reporting says

The pattern: every major headline used the married name, which explains why “Jamie Kah” searches stopped showing the win.
