"The whole process over the last six months has been about trying to get my body right and getting my action right to be back playing the longer format of the game.
"I am less than a week away from doing that and I am pretty excited at the moment.
"Hopefully I can use these three games and get some good performances on the board and feel good, and then I can put my name forward for selection for the West Indies."
In a bid to avoid further back injuries, Pattinson has remodelled his action working alongside Australian bowling coach Craig McDermott and Cricket Victoria high performance manager Tim McCaskill.
"Initially, I was not going to play any Big Bash cricket but I got to the stage where I had to play some cricket because it had been so long since I had, and I was ready to go," said Pattinson, who has claimed 51 wickets in his 13 tests at an average of 27.07.
"I managed to play five matches, which was fantastic.
"I was a bit nervous coming into the games, whether I could hold my action and actually compete at that level knowing I had been out of the game for so long but I was lucky enough to get a few wickets and stick to my [new] action too.
"It is a mouth-watering year ahead.
"The Ashes is the pinnacle and that is my goal, I want to be available for that series and I want to be performing well so I can put my name up for selection."
