Australia’s most successful captain, Ricky Ponting, is leading the charge for a major shake-up of the nation’s Test team after the No. 1-rated side was stunned by Bangladesh in Darwin.

The two-Test series was seen as a frolic in the tropics for the Aussies as they gear up for a 20-Test odyssey that will see them play in South Africa, India and England across the next 12 months, as well as a home series against Trans-Tasman rivals New Zealand.

However, the working holiday vibes were quickly dashed by a determined tourists who could never have imagined a nine-wicket victory over the world’s best Test team.

And it came just a week after they were dismissed for 54 in a tour game by an Australian representative side.

West Australian Cam Green was the only shining light on the final day of the contest, assuring his place in the side with his maiden century on home soil.

But for a top order who already had question marks, the spotlight intensifies.

The heat will mostly focus on opener Jake Weatherald and first drop Marnus Labuschagne, who again failed to make any real impact, but some of the side’s aging bowlers will also be put under pressure after Bangladesh amassed 426 from 138 overs in the first innings as a second-gamer scored triple figures.

Ponting said the result made change “inevitable” and added they should have bitten the bullet ahead of the series.

“I think it’s inevitable they have to make a change,” he said on commentary for Seven.

“I was on the record at the end of last summer thinking that this was the ideal time to start to regenerate this team because the performances from some of the players, and look, I’m the last one I want to make change.

“As a captain or as a player, I wanted to keep the group together. So it has to get to a bad point before I start saying you ought to leave somebody out.

“But there had been enough evidence for me coming here to suggest that they weren’t going to lose anything or much at all by starting that regeneration, by maybe bringing in another opener, by maybe bringing in someone at number three. And I think if they lose here, then I think that has to happen.

“They’ve been out-batted, they’ve been out-bowled and probably Bangladesh have probably fielded better as well. So to be in a situation they are, in Australian conditions, against a team from the subcontinent, not good.”

Fellow seven commentator and former New South Wales quick Trent Copeland labelled the disastrous loss “embarrassing”.

“This is completely an unacceptable result for Australia. This is an embarrassing loss,” he said.

Australia’s preparation will also come under fire for the third summer in a row after much of the team entered the Test with a single intra-squad hitout under their belts.

However, skipper Pat Cummins said his side was ready to compete in Darwin.

“Yeah...I think they outplayed us in all facets, really. I thought they were really patient and quite disciplined, and once we were behind, it was really hard to get back,” he said post-game.

“I thought our preparation was spot on; I thought it was excellent, so no excuses there.”

Another golden generation member, Mark Waugh, said Australia needed to make the change before they head to South Africa, which will be the team’s first appearance there since the Sandpaper Gate scandal.

“You have to bite the bullet at some stage if the batting keeps failing. It is as simple as that, no matter who the opposition is,” he said.

“I think Weatherald is the one most under pressure, and it would not surprise me if there were two changes. It would be nice to give someone a Test match leading into South Africa.”

Former Australian opener David Warner echoed Waugh’s sentiments.

“(South Africa) is a big, big challenge. They have a great bowling unit. Those conditions are not easy to play in,” Warner said.

“Would you be confident to take a batting unit that hasn’t got the weight of runs behind them? Is there going to be changes for that series? There might not be any changes after this game, just one Test, but what does that look like for that tour and for the Australian summer?”
