Ukrainian boxing legend Vasiliy Lomachenko secured the IBF lightweight world title on Sunday with a remarkable performance, stopping Australia's George Kambosos in the 11th round in Perth's packed 15,000-seat RAC Arena. Despite the hostile crowd, Lomachenko dominated the fight, leaving Kambosos bloodied and claiming the 135-pound belt, his first in the IBF lightweight category.

Lomachenko, a former WBA and WBC lightweight champion and two-time Olympic gold medalist, expressed joy at regaining the world title and hinted at spending time with his family, leaving his future in the sport uncertain. Kambosos, a former champion, acknowledged Lomachenko's greatness despite his pre-fight bravado and gave his best effort but fell short.

Both fighters aimed to redeem themselves after previous losses to Devin Haney. The fight was marked by intense exchanges, with Lomachenko's skill and speed proving decisive as he landed punishing blows, ultimately forcing the referee to stop the contest in the 11th round.

The undercard saw controversy as Pedro Guevara controversially defeated Andrew Moloney for the interim WBC super flyweight belt, prompting Moloney's immediate retirement announcement due to injury. Additionally, Cherneka Johnson claimed the women's WBA bantamweight belt in a hard-fought battle against Nina Hughes, despite initial confusion over the announcement of the winner.
