Australia narrowly defeated New Zealand 24-22 in the opening match of the Rugby League World Cup, held on a chilly, wet evening in Sydney before a crowd of 41,255. The tightly contested encounter saw debutant Jack Bostock emerge as the pivotal figure for Australia, scoring a hat-trick and providing a crucial assist in the final stages to secure victory for the Kangaroos.

Bostock, a 23-year-old winger for the Dolphins, made a significant impact on his international debut, including two intercept tries that swung momentum in Australia's favor despite New Zealand’s dominance in general play. His first try, an interception midway through the first half, set the tone for a match where much of the yardage and possession favored the Kiwis. Australia trailed in metrics such as average set distance and tackles, with New Zealand covering more ground and maintaining greater field position.

New Zealand’s fullback Kalyn Ponga was a standout performer, overcoming what appeared to be a painful arm injury to score two tries and challenge Australia’s defense throughout the contest. Ponga’s second-half efforts included a solo try that underscored his reputation as one of rugby league’s most electric players and appeared to confirm his status as the tournament's rising star following the injury of Australian playmaker Nathan Cleary. However, concerns remain over his fitness after he exited the game late with the arm injury.

Reece Walsh, Australia’s fullback, contributed significantly with a long-range try and linked effectively with Bostock on the decisive scoring plays. Walsh’s speed and elusiveness were critical in countering New Zealand’s attacks, although he also experienced handling errors that allowed the Kiwis to close the gap at various points.

New Zealand’s early dominance featured scoring contributions from centre Casey McLean and halfback Jamayne Isaako, who was reliable with goal-kicking, adding five points for his team. McLean’s try in the opening minutes showcased his emergence as a noteworthy player, further highlighting the depth of talent present among the Kiwis.

The match was marked by notable defensive stands and errors on both sides. For example, a double movement penalty denied New Zealand a try in a key moment, while Australia’s aggressive use of interceptions turned the tide despite being outplayed in most other aspects.

The tension culminated in the final minutes when Bostock leapt above Isaako to secure a contested catch and score his third try, putting Australia ahead. New Zealand struggled to mount a final attack with the sin binning of Kotoni Staggs for a late infringement and were unable to force extra time.

Australia’s coach Kelvin Walters praised Bostock’s maiden performance as exceptional, expressing optimism for the tournament ahead. Meanwhile, New Zealand coach Stacey Jones acknowledged uncertainty over Ponga’s injury but remained hopeful for the team’s prospects.

This closely fought match set the tone for what promises to be a fiercely competitive tournament, as both traditional rivals look ahead to a potential rematch in the final later this month.
