Australia captain Steve Smith said Paris's left-arm swing bowling in his home conditions swayed the selectors in his favour.
"Traditionally we like to play a left-armer here who can use the breeze and move the ball so hopefully he'll be able to do that for us," Smith said.
"He's been very impressive in the (one-day) Matador Cup in the last couple of years and in the T20 Big Bash this year. We look forward to seeing how he goes.
"It's a good opportunity for him and some other young quicks around the country. So it's an exciting time for Joel to make his debut at the WACA."
Boland gets the nod after being on the fringes of the Australian Test team this season.
"His death bowling has been very impressive," said Smith of Boland's efforts with the Melbourne Stars in the BBL.
"I think he hits a yorker as well as anyone at the moment. He's got a bit of pace to him so hopefully he can hurry up the Indian batters a bit."
Smith said he would decide who takes the important final overs of the Indian innings on the day.
"We've got a few options. All of our fast bowlers in this game can perform a role at the death," Smith said.
Shaun Marsh could not force his way back into the Australian team with George Bailey filling the batting spot left by the retirement of former captain Michael Clarke.
"It's very difficult but Shaun's been exceptional," Smith said.
Marsh has been unlucky this season after scoring his highest Test score of 182 in the first Test against the West Indies in Hobart, only to make way for the return from injury of Usman Khawaja in the second Melbourne Test.
"He hasn't whinged once. He's taken it on the chin and he's been great around the group," Smith said.
"He's been really impressive and hopefully every time he goes back (to state cricket) he can continue to dominate, keep scoring big runs and to put his name up there."
