Nikita Tszyu returns to Newcastle Entertainment Centre on Wednesday, May 6, looking to extend one of Australian boxing’s most remarkable records. The Tszyu family stands a perfect 13-0 in Newcastle — and now Nikita puts that legacy on the line against unbeaten Spanish contender Oscar Diaz (16-0) in a high-stakes showdown.
Undefeated at 11-0 with nine knockouts, Tszyu has already produced career-defining moments in Newcastle. Now he faces a dangerous opponent determined to disrupt the rise of one of Australia’s fastest-growing stars. With a stacked undercard featuring Olympian Callum Peters, CJ Mundine, Jack Bowen, Brandon Grach and strong local talent, this is a must-see night of Australian boxing.
