The Kangaroos are world champions for the 12th time, taking down Samoa 30-10 in the Rugby League World Cup final at Old Trafford.
The men's side's victory at the home of Manchester United completed a double for Australia, with the Jillaroos even more comprehensive in their 54-4 victory over New Zealand in the women's final.
But while the Jillaroos were up against their old rivals who they know inside and out, the Kangaroos faced a team of destiny in the shape of Samoa, but there was to be no fairytale underdog story.
The Pacific Islander stars never truly threatened to cause an upset in their first World Cup final, with the Australians boasting too much firepower across the park, as fullback and captain James Tedesco won player-of-the-match honours for his two-try performance.
He also broke seven tackles and ran for a game-high 199 metres, per StatsPerform.
The Kangaroos have not been beaten at a World Cup since losing the 2008 final to New Zealand, sporting a perfect 18-0 record, including three straight finals, since then.
That experienced showed for the full 80 minutes in Manchester, although an early refereeing blunder could have changed the complexion of at least the first exchanges.
In the fourth minute, Samoa hooker Chanel Harris-Tavita attempted a 40/20 that should have been awarded, but on-field officials missed Tedesco's toe on the line as he dove to bat the ball back in-field.
From there, Australia pounced on every mistake, getting a running start from a poor Jarome Luai kick into the in-goal, with Nathan Cleary sending Latrell Mitchell over for the opening try in the 14th minute on the back of the ensuing sets of six.
Tedesco got his first almost immediately after, with winger Josh Addo-Carr breaking through the middle and finding his skipper supporting through the middle.
Harry Grant sent Liam Martin over on the half-hour, and Australia took a 14-0 lead into half-time, but there was more drama to start the second stanza.
After a Valentine Holmes knock-on, Angus Crichton picked up the loose ball, and Harris-Tavita ran in to give Crichton a few words of advice, but the Australian back rower collected him with a forearm to the head.
Harris-Tavita was knocked out of what could be his final game, and Crichton was sin-binned for 10 minutes, but Samoa could not capitalise on their numerical advantage.
In fact, the Kangaroos managed to cross with just 12 men, with Cleary sending Cameron Murray through a hole with just under half an hour left.
Samoa got on the board, much to the crowd's delight, with Brian To'o on the end of a right-side shift that featured a stunning long ball from Luai, but Australia answered right back with a slick set play for Tedesco's second.
Stephen Crichton scored a trademark intercept try heading into the final 10 minutes, but it was too late for a comeback, with Mitchell's second sealing the victory.
Look back at how the men's final unfolded at Old Trafford.

Doing the double
What a night for Australian rugby league.
The Jillaroos' performance was certainly the most complete, but you can't argue with two World Cups out of two up for grabs on one night.
Another huge step towards equality, with the women's game given similar billing to the men's, and hopefully people saw the skill on display and will keep pushing the game further in that direction.
And that seems as good a time as any for me to call time.
We'll be back across the FIFA World Cup in coming weeks, and then for the summer of cricket.
Until then...

THE KANGAROOS WIN THE WORLD CUP YET AGAIN!
The conversion goes wide, so it's a 30-10 win for Australia's men's side.
No-one can say Australia didn't deserve to win that game, but it almost feels like an anti-climax, after Samoa's run to the final was so enthralling, for them to only get on the board late.
Honestly, the Australian side seemed to be peaking at the right time, while the Samoans genuinely looked tired out there.
Losing Chanel Harris-Tavita also completely messed with their set-up on both sides of the ball, and made it tough for them to fire a shot in the second half.
By Jon Healy
Latrell puts the cap on a famous win!
The play wasn't pretty in the lead-up, but Nathan Cleary fired out a cut-out ball to Latrell Mitchell in space and the Rabbitohs superstar did the rest.
What a sign-off from two of this team's guns who were maligned for underwhelming tournaments.

79th minute
Well that just seems mean, as Nathan Cleary belts a 40/20.
And we have a streaker. Good work. Height of comedy.
Anyway, Australia will run out the clock here.
By Jon Healy
78th minute
I thought the busted Spencer Leniu might get there, then Jarome Luai grubbered for himself, but Angus Crichton flew across from nowhere. Great effort play from the big forward.
By Jon Healy
76th minute
Latrell Mitchell strips Jaydn Su'a but knocks on in the process. So Samoa will reload from just on the wrong side of halfway.
By Jon Healy
75th minute
Cameron Munster tries a bunted grubber, but I think Angus Crichton overran him and was offside. Another nothing play from Munster. He hasn't been at his best tonight.
By Jon Healy
74th minute
Milford bombs from his 40m line. Australia needs to resettle now.
A set restart will help.

Stephen Crichton gets another intercept!
Is this guy a master of disguise or something? Opposition players just seem to find him.
This time it was Ben Hunt, who was just trying to pop a short ball from dummy half, and Crichton came from nowhere to tap it forward, chase it down, and score in the corner.
Crichton hits the post, so it's still 16 points the difference with eight minutes left.
By Jon Healy
Tedesco is in for a massive double!
Absolutely perfectly executed inside-outside play.
Every member of the spine got a touch: Ben Hunt going right from dummy half, turning it back for Nathan Cleary, who spins it out to Cameron Munster, who pops it back inside for the flying James Tedesco to burst through the gap at full speed and on a perfect line.
That's the back-breaker.

68th minute
Tino Fa'asuamaleaui joins the fray in the final 15 minutes for Australia.
Latrell Mitchell makes valuable metres through the middle, as does Reagan Campbell-Gillard.
By Jon Healy
65th minute
Oh Brian To'o is almost away on an intercept, but he couldn't stay on his feet as he swooped on Nathan Cleary's loose pass. Still, Samoa with the ball in good field position.
But Luai's pass goes to ground and the play dies out wide.
By Jon Healy
SAMOA IS IN! IT'S BRIAN TO'O!
It looked like the numbers matched up as Jarome Luai drifted across, and Latrell Mitchell went for the intercept on Luai's cut-out pass. But he only came up with air, and Kelma Tuilagi summed things up, sending To'o over out wide.
Stephen Crichton slots the sideline conversion. So this match is alive with 18 minutes left.
By Jon Healy
59th minute: The Kangaroos are in again, but no try
Josh Addo-Carr breaks down the left and kicks back infield for Angus Crichton, but he couldn't get the bounce, and fumbled with the line at his mercy.
The pass was probably on for Addo-Carr, but can't blame him for kicking, and Crichton really should've finished it off.
By Jon Healy
58th minute
Samoa tries to get something going with the offload game that's served them so well, but it ends in a knock-on at halfway.
The Kangaroos will launch another attack.
By Jon Healy
57th minute
Harry Grant tries a dummy-half sneak, but Joseph Suaali'i is strong enough to hold him up.
The Kangaroos are pinged for an obstruction, so a let-off for Samoa, but Angus Crichton is back on. So it's 13 vs 13 again.
By Jon Healy
55th minute
Two minutes left in the sin bin for Angus Crichton. Meanwhile, Samoa's line-up has been scrambled by the loss of hooker Chanel Harris-Tavita.
Milford is dummy half in attack, but defending in the halves. No clue who's partnering Luai in attack.
Cleary uncorks a spiral bomb, and Penrith teammate Stephen Crichton has hit the extended kicking leg in an attempted chargedown, spinning Cleary like a top and earning the Kangaroos a penalty.
By Jon Healy
Cameron Murray goes over for Australia!
My word. What a ball from Nathan Cleary. What a line from Cameron Murray. Makes it look very simple.
They're targeting Milford in defence, and it paid off there with a superb short ball to send Murray over basically untouched.
Cleary converts for 20-0.
By Jon Healy
51st minute
Another gift for Samoa, with Latrell Mitchell wrestling Papali'i off him, and knocking on as he tries to plant the ball to play it.
But Cameron Munster rips it back for Australia, robbing Spencer Leniu blind. Maybe targeting the dodgy shoulder.
