Fiery West Indies quick denies outburst was aimed at Mitchell Starc after Aussies suffer 7-68 collapse

Australia lost 7-68 to be bowled out for 225 on day one of the third West Indies Test as fiery local quick Jayden Seales seemingly delivered a couple of vicious send-offs that may result in more scrutiny from officials.

Seales removed Cameron Green with a jaffa as well as Mitchell Starc and Pat Cummins en route to registering figures of 3-59 in the day-night Test in Kingston, but the right-arm paceman could yet be sanctioned for the second time in the three-Test series.

The ESPN broadcast didn't show it, but according to respected cricket reporter Bharat Sundaresan, Seales was jumping up and down and yelling in Smith's face after Australia's No.4 was dismissed for 48 by Shamar Joseph in the 56th over.

The departure of Smith saw Australia slip to 4-157 and triggered the 7-68 collapse, with all seven of those wickets falling inside 15 overs.

In the 68th over in the Jamaican capital, Seales ripped through Starc's defence and then appeared to deliver the tail-ender an intense send-off, seemingly pointing at him and firing off some choice words.

However, he denied that he had directed his anger at Starc.

"No send-off — that was pointed directly towards Alzarri [Joseph]. We had a conversation before the delivery. No send-offs," Seales said at stumps.

"I'm not planning to get any fines or push the limits with the umpires anymore, so definitely not crossing that line."

Seales was docked 15 per cent of his match fee after giving Cummins a send-off in the first Test and the 23-year-old is now likely set to face more heat from International Cricket Council officials.

Despite the send-off Seales seemingly gave Smith, the Australian claimed at stumps to have not noticed it.

"Wouldn't have a clue," Smith told reporters.

"I didn't hear anything. No idea."

Australia's all-pace attack, selected at the expense of dropped off-spinner Nathan Lyon, had nine overs at the West Indies before stumps.

And as he's done on so many occasions in his 100-Test career, Starc jagged a wicket with the new ball when he bowled opening batter Kevlon Anderson for 3 at Sabina Park.

Brandon King and captain Roston Chase will continue on 8 and 3 respectively when the West Indies resume on day two at 1-16.

Both of Australia's opening batters failed with Sam Konstas losing his wicket for 17 and Usman Khawaja 23.

Green (46) and Smith (48) made some runs of substance in a rescue of sorts, but the West Indies' quicks were soon tearing through the visitors with the pink ball under lights.

To remove Green, Seales brought Australia's first drop forward, beat his outside edge off the seam and hit the top of off.

Eighteen months after inflicting carnage at the Gabba, Shamar Joseph took 4-33 in another destructive display with the ball against Australia.

The right-arm quick claimed the wickets of Khawaja, Smith, Beau Webster and Josh Hazlewood.

Even Smith, arguably Australia's best Test batter since Sir Donald Bradman, admitted he struggled against the pink ball.

"The pink ball in general is just a completely different game," Smith told reporters at stumps.

"Personally, I find it quite tricky just picking the ball up at certain times of the day ... and the way it behaves is completely different to the red one.

"People like the spectacle but as a player, particularly as a batter, it's very challenging.

"The game can turn so quickly and things change really quickly, which you probably don't get so much with the red ball.

"But people like watching it, I suppose, so I guess it's here to stay."

Australia won the first two Tests to retain the Frank Worrell Trophy.
