Australian two-time bantamweight world title challenger Jason “Mayhem” Moloney and New Zealand-born heavyweight contender Junior Fa hope to showcase their talents for the home region fans at Marvel Stadium in Melbourne, Australia, on the undercard of the George Kambosos Jr.-Devin Haney undisputed lightweight world title showdown. The Kambosos-Haney world championship event is projected to be one of the biggest boxing events ever on Australian soil.
 
Moloney will battle former world title challenger Aston Palicte in a 10-rounder for the vacant WBO International bantamweight title, while Fa will take on Australian fan-favorite Lucas Browne in a 10-rounder for the WBA Oceania and IBF International heavyweight title belts.
 
Kambosos-Haney, Moloney-Palicte, Fa-Browne, and an eight-round heavyweight fight between Hemi Ahio (18-0, 13 KOs), Auckland, New Zealand, and Joe Jones (13-4, 10 KOs), of Jersey City. N.J, will be televised LIVE on ESPN, ESPN Deportes and ESPN+ Saturday, June 4, at 9 p.m. ET/6 p.m. PT.
 
In a swing bout, cruiserweight David Nyika (2-0, 2 KOs) will be showcased in 6/4-rounder against an opponent to be named. Nyika, from Hamilton, New Zealand, captured a bronze medal at the Tokyo Olympics last summer. A beloved sporting hero in his country, Nyika has earned his stripes as a sparring partner for heavyweight champion Tyson Fury.
 
Following the main event, streaming live and exclusively in the United States on ESPN+, world-rated junior bantamweight contender Andrew Moloney (23-2, 15 KOs) will battle Nicaragua’s Alexander Espinoza (21-3-2, 8 KOs) in an eight-rounder, and Devin Haney Promotions-signed junior middleweight prospect Amari Jones (5-0, 5 KOs) will fight Ankush Hooda (3-0-1, 1 KO) in a scheduled six-rounder.
 
“When it comes to presenting an undercard worthy of its main event — the battle between world champions George Kambosos Jr. and Devin Haney for the undisputed lightweight world championship — it's Aussie Rules.  Australian fight fans in Marvel Stadium and viewers around the globe will be treated to a feast of exciting all-action bouts, many featuring contenders and prospects from Australia, as well as New Zealand. And those not televised live on ESPN will be streamed to the U.S. on ESPN+,” said Lou DiBella, President of DiBella Entertainment.  “We are prepared to make history in Melbourne.”
 
Browne (30-3, 26 KOs) won the WBA Oceania title with a knockout victory over Faiga Opelu in December and is a former WBA world titlist. The 32-year-old Fa (19-1, 10 KOs) is looking to get his career back on track after losing to former world champion Joseph Parker in his last outing in February 2021. Fa has notable wins over American veterans Devin Vargas and Dominick Guinn.
