"Mitch Marsh probably hasn't been as consistent as he would like and we would like", Paine said, confirming that Marsh would be a likely inclusion later on in the Test summer.
2018 will go down as one of the most hard years for the Australian test team but after tough tours to South Africa and the UAE against Pakistan where they lost both series, they return home now where they are notoriously strong to play India.
This is somewhat of a gamble to take in the first day Test at Adelaide Oval in four years, particularly if Virat Kohli calls correctly at the toss and bats first with temperatures expected to soar to 39 on Thursday and into the mid-30s the following day. However, ahead of the third and final - a stern Test against Australia in Australia, the Asian giants are being tipped as favourites.
"That's why I feel that India have got a big chance because they are a settled unit and they will be confident".
The dumping of Mitch Marsh will add an extra burden for Josh Hazlewood, Mitchell Starc, Pat Cummins and spinner Nathan Lyon, who will have to take on more overs in what are forecast to be scorching hot conditions in Adelaide.
Paine confirmed Marcus Harris would make his Test debut and open the batting with Aaron Finch in the series opener, Australia's first home Test since Steve Smith and David Warner were banned over the Newlands ball-tampering scandal. "It is going to be no different for them; they are going to see at times if they can attack Nathan and get on top of him and we're going to have bowl our quicks a bit more than we would like so it is going to be a real chess match in that regard". We've obviously got a lot of confidence in Nathan Lyon bowling a lot of overs if we need to.
"It's probably unlikely we'll use the three quicks as much we will this game through the whole series as it wears on". In 44 Tests on Australian soil, they have only managed five wins thus far.
"We have options there but we'll be backing our bowlers", Paine said.
