Mack Hansen scored a stunning first half hat-trick as Ireland saw off Australia in Dublin

Mack Hansen grabbed a 28-minute hat-trick as Ireland secured a record and morale-boosting 46-19 victory over Australia in Dublin.

Caelan Doris, Ryan Baird and Robbie Henshaw scored further tries to add to Hansen's treble, as Ireland kicked on in the second half to see off a jaded Wallabies side playing their 14th Test since July.

Fly-halves Sam Prendergast (two conversions, one drop-goal) and Jack Crowley (one penalty, three conversions) added further points on a day of positives for Andy Farrell's Ireland.

Farrell led the British and Irish Lions to a 2-1 series victory over Schmidt's Wallabies in the summer following Ireland's 22-19 victory over the same opponents last November.

His side - showing nine personnel changes from last weekend's disjointed 41-10 success over Japan - were rewarded for a rapid start on a soggy Saturday evening.

Hansen crossed twice in the opening 11 minutes, diving under the posts after being teed up by Stuart McCloskey following a quick-tap penalty before collecting a Prendergast pass to register a carbon-copy effort.

Australia, who suffered a shock defeat to Italy last weekend and had lost five of their previous six Tests, responded when centre Ikitau beat Prendergast to barrel over.

Hansen, whose mother hails from Cork, then further punished his homeland, powering across the line wide on the right after Prendergast's miscued kick was spilled backwards by Tommy O'Brien.

Yet the Wallabies were only 19-14 behind at the interval as flanker McReight crashed over in the final play of the half, with fly-half James O'Connor adding his second conversion.

Ireland had struggled to set pulses racing with their performances this month and would have been eager to secure greater control of the scoreboard.

After hooker Dan Sheehan was held up on the line, Prendergast nailed a drop goal from distance before providing a crossfield kick assist for O'Brien, only for the score to be disallowed for a knock-on in the build-up.

Crowley - on in place of Prendergast - slotted a penalty to stretch the score to 25-14.

Captain Doris then bulldozed over at the end of sustained pressure, with Crowley adding a superb conversion, before Australia were left to play the final 10 minutes a man down after replacement lock Nick Frost was sin-binned for a high tackle on Tom Clarkson in the build up.

Despite the Wallabies' numerical disadvantage, replacement hooker Pollard went over to reduce the deficit.

But Ireland twice responded to seal an emphatic, six-try victory, with Baird crashing over before Henshaw raced clear down the left after being released by a sensational kick from Jamison Gibson-Park followed a lovely Crowley chip.
