Australia v Ireland - Nations Championship live updates and latest as Wallabies replacement Tate McDermott gives side lead in epic clash

Australia had the opportunity to add some vital points to their tally. However, Donaldson’s effort is caught in the wind and flies just wide.

Australia have survived the spell of Ireland pressure and are now looking to land a killer blow themselves. Ryan gives away a penalty and retaliates out of frustration.

Timoney finds a gap in the Wallabies’ defence and charges through to gain 20 metres of ground. The ball is recycled out to Ryan, but the ball drops through his hands under a tackle.

The Wallabies are desperate to increase their advantage and Jorgensen believed he had space out wide. However, Keenan stood in his path  and was an immovable object to stifle the attack.

After receiving treatment Lonergan makes way.

There is little between the two sides heading into the final 20 minutes. Ireland are much improved in this second half and will believe they can snatch the win.

Ireland are denied a try. A line-out results in a driving maul and around the corner Sheehan is on hand to roll over.

The conversion is again good and Ireland looked to have the lead. However, TMO saw that Ryan had blocked a defender after disconnecting from the runner.

The try is ruled out

Paenga‑Amosa, Slipper and Tupou are all on.

From the Australian scum a quick moment of thinking from the scrum half Gordon. He falls a metre short before McDermott provides the final drive to push him over. Gordon also scores the resulting conversion to regain the lead.

Four replacements for Ireland as the visitors throw on a host of new faces in the pack

Australia looked for an immediate response but were met by a stubborn defence. The visitors concede a penalty but hold out.

Phase after phase of Ireland pressure results in a penalty advantage and the Wallabies being pushed back. From the ruck Gibson‑Park finds the driving run of Keenan to score.

That’s Ireland’s fourth try from five 22 visits. The conversion under the post is slotted over.

McCloskey fooled his tackler with a show-and-go before driving forward and putting Ireland back into the Australian half.

Moments like that will give Ireland renewed optimism in this second half.

The Ireland lock was a little too keen in that tackle and grabbed his opponent by the neck. That infringement allows the Wallabies to gain ground early in the half.

It was a memorable first half and if the second 40 minutes is the same then we’re in for a treat. We’re back underway

Ireland have shown their battling qualities to remain in this match. However, the young Wallabies have been impressive to watch and if they can continue at that pace then Ireland will struggle in the second 40.

Ireland have been punished by three lost line-outs which all resulted in key moments up the other end of the pitch.

That was the final play in a non-stop first half containing seven tries. The Wallabies may reflect on that missed Jorgensen chance which would have put them out of sight at half-time.

Instead it’s Ireland who go in at the break just five points behind.

It’s a beautiful passing try from Ireland which started inside their own 22-metre line. The Wallabies fail to pick up Gibson‑Park’s run to score from Conan’s pass.

The Wallabies forwards make some crunching challenges before silky passing out wide results in an opportunity for Jorgensen.

However, the winger is a yard off the pace.
