Shane Warne and Ricky Ponting are gunning for Dennis Lillee and Viv Richards.
The peerless Australian leg spinner and his run-plundering captain have produced such bumper individual seasons that the test records for most wickets and runs in a calendar year - two benchmarks that were supposed to be untouchable - are under attack.
Former Australian skipper Mark Taylor believes Ponting has overtaken Brian Lara and Sachin Tendulkar as the world's finest batsman, and predicts he will give Richards's mark of 1710 runs an almighty shake.
Lillee knows his 24-year-old record for most wickets in a year (85) is as good as gone because the magnificent Warne has 73 already, with four more Tests to go.
"If the record has to be broken, and I suppose it does, I'm glad it's going to him," Lillee said. "He's an amazing cricketer. Amazing isn't a strong enough word. You talk about great players - this is a truly great player. The record is all his."
To put Warne's phenomenal year into perspective, the 36-year-old has already taken more wickets (from five fewer Tests) than he did in his pomp in 1993, the year of his Mike Gatting ball and assorted other tricks. This at an age when he should be past it. He continues to defy belief.
"Incredible," Lillee said. "What else can you say about him?"
Richards hit 1710 runs in 1976 in a performance of such sustained quality that his figures have never been threatened.
With up to eight innings to go, Ponting is 494 runs short. Given the 253 he pummelled in the first Test against the West Indies and given the weakness of the Windies attack, Ponting can do it. Difficult, yes. Impossible, no.
"He's a chance," Taylor said. "If he can have another Test match like the last, he's going to come very close.
"Most people suggest that Viv's record was never going to be beaten but the fact we can even discuss it seriously means Ricky is having a fine year."
Warne and Ponting have been Australian teammates for a decade - and it was Warne who gave "Punter" his nickname.
"That all started back in about 1992 or 1993 at the cricket academy," Ponting said. "I was there at a very young age, 15 or 16. Warney had just been picked on his first Australian tour to Sri Lanka. He came down and spent some time with us.
"I was too young to go out but Warney would grab me and try to dress me up in a good pair of pants and a shirt and try to take me out.
"I headed down to the pub and had a bet on the greyhounds. Warney said, 'You're a little punter, aren't ya?' and I said, 'Yeah I am'. It's stuck from there."
Debate about the identity of the world's best batsman routinely revolves around Lara and Tendulkar. Care to argue with Ponting being No.1? Lara is too inconsistent, Tendulkar has a glass elbow.
Jacques Kallis and Rahul Dravid? Nup, it's got to be Ponting.
His Test average after 95 appearances is 56.75 compared with Lara's 53.44 and Tendulkar's 57.25. He is not out of place in their company.
"We often talk about Lara and Tendulkar," Taylor said. "But watching Brian play the first Test match and looking at his numbers in recent times compared with those of Ricky, Ricky is playing much better.
"Brian is absolutely trying his guts out. It looks to me like he's knuckling down and doing everything in his power to do well for the West Indies but he just can't seem to get on top.
"Ricky seems to dominate more often than not when he's at the crease. I don't think there's any finer player in the world at the moment."
Taylor was Australian captain when Ponting made his Test debut in 1995. David Boon was batting at No.3.
"You have to put him in the top echelon of batsmen in the world," Boon said. "His performances over the last few years have been outstanding. Most impressive is when and where he has scored.
"That's very important. Some of his hundreds have come when a game has been tight or in a big occasion. A prime example would be Manchester [in the Ashes series] this year. There was the [2003] World Cup final. As a leader, he's doing a fantastic job.
"You always want your players to follow your leader and have respect for your leader. The players admire him and their relationship within the team is extremely buoyant. He leads from the front and his cricket knowledge is exemplary."
Taylor said Ponting was not exactly shy and retiring as a debutant but took a little while to perk up in the dressing room.
Ponting was understandably "a little peeved" by his lbw verdict on 96 in his first Test innings from a ball that was going over the stumps.
Boon said it was clear from Ponting's early days that he was destined to occupy his current lofty position in the pecking order of world batsmen.
Asked during the week to nominate Australia's best batsman since Don Bradman, Ponting opted for Matthew Hayden. Hayden would undoubtedly return the compliment.
