Pattinson has been dogged by injuries, mainly in his back, throughout his career. He underwent surgery in November 2017 in a last ditch attempt to resolve the problems, without returning to the Victorian team of Sheffield Shield until the beginning of last season.
He played as a handyman before Christmas, increasing his workloads in the second half of the season, when his spicy form booked him a place in the plane for England.
Pattinson debuted in the New Zealand test in 2011 in the same game as David Warner and Mitchell Starc, but he played the fewest games of that trio with a considerable margin.
Warner has played 78 tests, even with 12 months of suspension, Starc 52 while Pattinson has queued in just 19.
"James Pattinson is again someone who really enjoyed us for what he did in the Test cricket here," said Paine.
"He is playing bowling very, very well, it will be a great resource for us as we go along. We have been saying right from the start that we want to make sure we take care of him, so he has many more years of Test cricket in him. We don't I look forward to bringing it back to Australia and freeing it during the summer. "
Before this series, Australia had never had the quartet of stars of Pattinson, Starc, Josh Hazlewood and Pat Cummins available at the same time. If they all stay in shape, Australia will have little chance of defeating Pakistan this summer, regardless of their problems with the bat.
"Clearly, our largest, tallest and fastest pitchers work really well in Australia," said Paine. "That's where we see six really exciting months for James Pattinson, Mitchell Starc, who has never played so much in this series.
"We think our house conditions fit really well to those two. We are excited, we will have them fresh and ready to go home for the summer, which is great. We have certainly taken a slightly different approach to things here this time."
Mitchell Marsh is back for his first game from the Boxing Test of last summer, his last appearance for Australia in any format.
The handyman put the writing on the wall for his recall with 74 and three wickets in a touring match against Derbyshire. It was chosen to lighten the burden incurred by the rapid Australians, who have campaigned extensively in England.
Marsh was told that after his test axing he needed to get in better shape and improve his game.
"He got quite honest feedback when he was dropped for the Indian series," Paine said.
"He had a choice to make, either with a pout or something. Mitch is currently as fit as we saw."
The Australians want Marsh to aspire to the fitness standards set by Ben Stokes, who was able to exceed 25-30 championships, but he still has the constitution to make hundreds.
"It's something that Mitch has observed closely and something he aspires to," said Paine.
"Certainly when he is in better shape, his bowling goes to another level. If you are a boy of the size he is, it is difficult to run all day when you bring a few extra pounds. He has worked hard to eliminate them."
