Sadly for Labuschagne his celebrations didn’t last long as he was sent packing just before the lunch break after notching a stunning 204.
Smith then carried on his own brilliant innings after being joined at the crease by Travis Head.
With plenty of runs on the board, Head didn’t waste any time as he put the foot down immediately and raced to his half century from 61 deliveries.
As the runs continued to pile up questions turned to when the Aussies would call time and send the West Indies into bat.
As the third and final session got underway Smith and Head inched closer to their milestones with Smith saluting his own double century with a quick single.
It left Head on the crease needing only one run to bring up his century, but it all went horribly wrong as he chopped a delivery from Kraigg Brathwaite onto his stumps.
Skipper Pat Cummins waved an end to the innings as Head walked off with his head slumped.
It means only opener David Warner failed to cash in on the run-onslaught after he chopped on for five runs.
Smith and Labuschagne combined for a 251-run stand, their biggest ever partnership in Test cricket.
The West Indies were sent in to face a tough 25-overs after close to two days in the field under scorching Perth conditions.
Tagenarine Chanderpaul made his Test batting debut and was thrown into the fire early on when Mitch Starc clattered a delivery into his pads. After a review the youngster remained by the slimmest of margins.
Only a handful of overs later however he was struck again, this time by Josh Hazlewood but painfully it slammed into his groin.
After a brief stumble away from the crease he hit the deck as a West Indies trainer ran onto the ground to check him over.
Warning, the following footage will make any man wince.
Chanderpaul shook off the painful blow and set about building the West Indian innings alongside skipper Brathwaite.
At the end of the second day’s play the West Indies were 0/74 as they look to hunt down the monster first innings total from the Aussies.

7pm – Aussies lose early review
Mitch Starc thought he had Tagenarine Chanderpaul in his second over after slamming a delivery into the youngster’s pads.
A lengthy discussion between the players unfolded before Pat Cummins called for the review.
After originally being given not out, the ball tracking showed the ball hitting the top of the stumps, but not enough to overturn the umpires decision.
6.35pm – Head bowled as Aussies declare
Travis Head’s innings came to an end in heartbreaking fashion as he chopped on a delivery from Kraigg Brathwaite.
Australia was on the brink of calling time on the innings as they waited for Head to bring up his milestone.
But in devastating fashion it wasn’t to be as Head looked to work a delivery down through the slip region only for a bottom edge to rattle into the stumps.
The brutal batting onslaught was brought to an end after Head’s dismissal which came shortly after Steve Smith brought up his double century.
Opener David Warner missed out on the run-scoring onslaught after being knocked over for only 5 runs. Fellow opener Usman Khawaja scored 65 runs to be the second lowest for the Aussies.
Smith and Marnus Labuschagne both scored double centuries as the Aussies fell just shy of the 600 mark.
6pm – When is the declaration coming
It’s the question on everyone’s minds as the tea break on day two is called with the Aussies sitting at 3/567.
Steve Smith remains unbeaten on 189 with Travis Head on 80 from only eighty deliveries. The session was another wicketless one for the Aussies as Smith and Head combined for a 166-run partnership. The second highest of the innings behind Smith and Labuschagne’s 251-run stand.
The Aussies are expected to call time once Smith and Head reach their double century and century milestones. Forcing the West Indies to face a few hours after almost two days in the field.
5.30pm – The run onslaught carries on
For the ninth time in his illustrious career, Steve Smith has surpassed the 150 run mark as the Aussie total surpasses 500 on day 2.
Marnus Labuschagne’s departure brought Travis Head to the crease who applied instant pressure by racing to 50 runs from only 51 deliveries as Smith continued to ply away.
Smith’s masterful innings drew heavy praise from Ricky Ponting and the changes he made to his technique.
“He’s talked all week, and we’ve talked about it in comms about his changes and he said to us it was all about freeing up his off-side play,” Ponting said on Channel 7’s coverage.
“What I have seen in this game, it’s actually freed up his leg- side play. It’s made him a better puller of the ball already in a couple of days. I think that’s because he’s been looking ahead to the South African series and who he might face there.”
The questions now turn to when the Aussies will call time on the innings and send the West Indies in who have spent two days under the scorching Perth conditions.
3.20pm – Smith equals Sir Donald
Steve Smith has raised the bat after producing a masterful innings alongside Marnus Labuschagne.
It makes it Smith’s 29th Test century, drawing him level with Sir Donald Bradman for fourth on the all-time Australian list.
Only minutes after Smith raised his bat, Labuschagne again raised both hands to the heavens as he made it to 200 unbeaten.
He becomes only the third player this year to score a double century in Test cricket.
Marnus’ innings came to an end on the stroke of lunch at 204 runs when he was caught behind off the bowling of part-time spinner Kraigg Brathwaite.
2.30pm – Marnus and Smith shatter record
The dominant Aussie duo are continuing to put the West Indies attack to the sword on day 2.
After Smith joined Labuschagne at the crease following the fall of Usman Khawaja, leaving the Aussies at 2/151.
But the star duo quickly turned the blowtorch back onto the tourists as they combined for a partnership of 211, so far.
It’s their biggest partnership together in Test cricket.
1:00pm – Marnus ‘calming down a bit’
Marnus Labuschagne has explained some of the sutble changes to his batting ahead of the second day of his magnificent innings.
Speaking to Fox Cricket, Marnus was asked if he was actively trying to minimise his unique mannerisms while batting out on the pitch.
The star batsman suggested he might be “calming down a little more,” although it clearly hasn’t been a purposeful step to remove his unique quirks.
12:30pm – Smith good to go after injury scare
Steve Smith is ready to rock on Day 2 despite an injury scare on Wednesday that left him needing treatment out on the field.
The batting superstar is “all ok” according to Cricket Australia after going down with a sore left hip, the same hip he was struggling with in the lead-up to the Test.
He resumes his innings on 59.
