Eddie Osei-Nketia

Osei-Nketia was born in Auckland, New Zealand to parents of Ghanaian descent.^[3] His father, Gus Nketia, is a former New Zealand national 100m record holder; a record that Eddie broke in 2022.^[4] Eddie initially grew up in the Whangaparāoa Peninsula until he relocated with his family to Canberra, Australia in 2010 at the age of nine for better sporting and educational opportunities.^[5] While in Canberra, he attended St Edmund's College where he played rugby union along with competing in athletics events.^[6] As a teenager, he represented the ACT at several Australian national junior athletics championship events.^[7] In early 2019, at the age of 17, Osei-Nketia moved back to New Zealand to live in Wellington and finish his secondary schooling commitments at Scots College.^[8]

As a dual citizen, Osei-Nketia initially represented New Zealand in international competitions and won the 100m Australian national title at 18 years old in 2019.^[9] After Osei-Nketia was controversially left out of the New Zealand's Olympic and Commonwealth Games national teams in 2021 and 2022, he decided to cease representing New Zealand in international competitions.^[10] He briefly pursued an American football career as a wide receiver at the University of Hawaii before accepting a track scholarship at University of Southern California and officially switched back to represent Australia in international competitions in December 2025.^[11] His younger brother, Augustine Nketia Junior, is also a sprinter who competes internationally for Australia.^[12]

In June 2019, Osei-Nketia won the 100 m at the Oceania Championships in Townsville.

On 28 September 2019, Osei-Nketia came fifth in his heat of the first round of the 100m at the World Athletics Championships in Doha, Qatar with a time of 10.24s, missing out on a semi-final berth by 0.01s.^[13] Osei-Nketia won the 2019 Australian Athletics Championships 100m in 10.22 after running a personal best of 10.19 in the semi-final.^[14]

On 27 March 2021 he ran 10.12 in Brisbane, ranking him second on the New Zealand all-time list, 0.01 sec behind the National Record set by his father, Gus Nketia, in 1994,^[15] qualifying him by ranking for the 2020 Summer Olympics, but he was not nominated.^[16]

Osei-Nketia broke his father's NZ 100m record in finishing second in the 7th heat of the 100m 2022 World Athletics Championships in 10.08 seconds (−0.3 m/s) on 15 July 2022.^[17]

Osei-Nketia transferred his allegiance to Australia on 4 December 2025^[18] and was subsequently named in the Australian team for the 2026 World Athletics Relays^[19] (though he did not attend due to other commitments).

In April 2026, he broke the Australian all-conditions 100m record previously held by Patrick Johnson by running a time of 9.84 seconds (+2.8w) during the 2026 Mt. SAC Relays in Walnut, California, United States.^[20][21] He further improved that record running 9.74 (+5.6w) at the Big Ten NCAA Division I athletic conference on 17 May 2026.
