From the kick off to get the match underway, it was clear that the Irish were prepared to match the Kumuls’ hard, straight running as they charged out of the line in the opening set.
Their fast paced start to the match paid off in just the fourth minute of the match as Irish hooker, Michael McIlorum, was the beneficiary of some luck of the Irish.
On the fifth tackle play broke down as the Irish started throwing the ball around desperately trying to create something.
The ball ended up on the flanks as they sent the ball up in the air before a cruel bounce gifted McIlorum an early four-pointer.

But in the 16th minute, PNG would finally get the breakthrough they were searching for through none other than fan favourite Garry Lo.
Shifting the ball across the field, Kato Ottio tapped the ball on for Lo who looked up to see a wall of green in front of him. But despite the attention, Lo was able to beat seven Irish defenders on his way to the line as Port Moresby erupted with cheers.

With the wind blowing Martin’s conversion attempt across the face of the posts, Ireland was still right in contention, trailing by just two points despite having few attacking chances.
Errors once again stained the final minutes of the first half as the siren signalled time for a much needed breather for both sides.
