You are right since winning the 2023 world cup Australia team is in great form they are playing well in every match. Especially in the three Test matches against Pakistan, Australia's batsmen have batted exceptionally well. Australia team has won three Test matches due to excellent batting. Australia team will do very well against West Indies because every Australian player bats well. Australia's bowling is excellent so it looks like they will do very well against the West Indies. Maybe West Indies team can do well in T20 if they play well Westin T20 match we will see competitive match. On the one hand the players of the Australian national team are doing great and on the other hand the Australian women's team is winning with a bang against India.
Australians are true professionals and their cricket board is very supportive of their players. And that is also one of the reasons why Australian players are some of the highest paid cricketers in the world. Indian players on the other hand are swimming in wads of cash, but they focus more on showoff rather than professionalism. And now coming to West Indies, I am not sure whether they can be competitive against the Australians. They performed poorly in the tour match against Cricket Australia XI (which didn't had any player with international experience).
Currently, Australians are doing one of the best things in sports, and they are surely taking good benefit of them as well like cricket at the top and rugby and field hockey are also best and few other sports they are enjoying because they are grooming their youths from early ages and bring best of them at right time which is surely amazing with now it's time for the Indians to learn and bring some better changes even it's not easy and not happening in near future because too many problems and other difficulties which are clearly not allowing them, but now money is also not used wisely which is also creating problems.
West Indies could be going for like we have Pakistan few days back and most chances these two test matches are going to be one-sided affair but good for the home side as thy will be able to have the good number of points for the WTC league table.
