Shamar keeps the spotlight on Australia's struggling top order

Things may yet turn out alright on the night for Australia in Barbados in terms of the result - although that remains far from certain - but the opening day of the series shone a further light on the task of reshaping the top order with an eye to the future.

Firstly, a qualifier: these were not comfortable batting conditions. Travis Head, who produced the most dominant innings, said that Australia had been taken by surprise with how tough they were, but Jayden Seales suggested West Indies had an inkling of what to expect after the pre-series training camp here.

Still, Australia's 22 for 3 - and a later collapse of 7 for 69 - followed on from the difficulties they had in the World Test Championship final against South Africa when they couldn't find a way through tricky periods. West Indies had struggles of their own, but it was a reminder that the next generation of Australia batting could be a longer-term project riddled with uncertainties.

You only need to show Shamar Joseph an Australia batting line-up for him to put on a display. He had not quite hit the heights of the Gabba since that heady day (although, after his struggles in England last year, the numbers had been far from dire) but this brought back memories of Brisbane.

His opening spell, and specifically the dismissal of Sam Konstas, set the tone for a well-planned West Indies bowling performance which held its nerve as Head and Usman Khawaja forged the best stand of the day, 89 runs, although it could have been better with safer catching.

Konstas was beautifully set-up by Joseph, falling in a manner that has been seen before at Australia Under-19 level and in his early domestic days with the ball shaping back at him.

"I think I set it up perfect towards him; a few outswingers, and then get the ball to nip back, because he's just looking to get beaten outside off and then to nip back through the gate," Joseph told ESPN's Around the Wicket, while speaking of the importance of the work he had put since the white-ball tour of the UK.

Joseph followed by giving Cameron Green a working over at No. 3, having him dropped second ball in the gully before he edged low to second slip. Ahead of the match, Pat Cummins said he saw Green as a long-term option at No. 3 but, while he's had some tough conditions to face - firstly Kagiso Rabada at Lord's and now another good pace attack - he will need a more convincing second innings to quieten the debate.

The best of the lot, though, was saved for Beau Webster who was completely turned around by a magnificent delivery that took the top of the stumps. "That's probably one of the best deliveries I've ever bowled," Joseph said.

Without Steven Smith (albeit temporarily) and Marnus Labuschagne, this batting order is without nearly 15,000 Test runs and it was something West Indies had taken note of.

"We spoke about it," Seales said. "We knew that coming into the Caribbean, pitches are a lot slower than what they were accustomed to in Australia. And especially this pitch, with the grass being how it is and the colour of the pitch, we knew that there was vulnerability within the batting line-up and more so with the pitch, so we just tried our best to exploit it."

'I don't think there's one solid way of going about things on those sort of wickets. You've just got to double down on your plan and your blueprint and what you play best'Travis Head

It took Australia 16 overs - and three wickets - to find the boundary, but Head defended the approach of the top order, backing each player to work out their own method.

"I thought Usman applied himself really well in the partnership and batted completely different to what I did, and both were as effective as each other," he said. "Guys will want to learn, you always want to try to adapt to the conditions the best way we can. We battled hard against a really quality attack, so on another day, you hope you get through it."

"I don't think there's one solid way of going about things on those sort of wickets. You've just got to double down on your plan and your blueprint and what you play best. Naturally, I like to try and put as much pressure back on and there's going to be times where it works and not."

Seales, who had claimed his first wicket when he removed the recalled Josh Inglis to a pull shot, was able to beat his team-mate to a five-wicket haul. He termed it the "most special" of the three he has bagged because he never quite felt at his best, but ensured Joseph took the acclaim as he left the field.

"I think that's what opened the game right up for us," he said of Joseph's early spell. "Blowing away the top order is the most important thing in Test cricket and then that made it a lot easier for us in the middle and in the back end of the innings."

Between them, their nine wickets left Australia needing the bowlers to keep them in the contest which, for the final 20 overs of the day, they did commendably as they so often have. But all eyes will be on that top order again come the second innings.
