The squad announcement is live on Sky Sports News, talkSport and Fox Tel in Australia at 11am BST and you'll know who's in and who's out at the same time as those desperate to star Down Under.
"The players are going to find out with the rest of the rugby world," said Gatland.
"In the past, we've text players and there's been a bit of a leak and people have known. So no-one's going to know this time."
Gatland faces a tough task to select a squad of around 35-38 players for the 10-match tour but he says that stems from the fact that he is blessed with too many options rather than too few.
"Selection is just a matter of opinion - that's all it is," added Gatland.
"That's what we've been charged to do (pick a squad to beat the Wallabies), and that's the difficult thing.
"The positive thing for us is that there are so many choices. We feel like there are three or four people in certain positions who could do a job for us.
"We're not worrying about who we're going to select - it's more about who we're going to leave out."
Whichever individuals he picks next week, Gatland insists that the collective nature of the squad will be central to their chances of series success in Oz.
Much has been made of the spirit of the last Lions side to taste Test glory in the southern hemisphere, with the class of 1997 bonding brilliantly both on and off the field.
Gatland intends to harness that sense of togetherness as quickly as possible as he believes it will be key to their hopes of returning home victorious in early July.
"I've definitely paid attention to past tours. It's important that I look at previous tours and talk to people who've been on those tours.
"What's come out of talking to players and coaches is that the harmony between the squad has been a big part of the success of Lions tours.
"It's really about getting the rugby right but also embracing some of the traditions that the Lions has been about in the past. It's about getting that balance right."
