With 15 of their regular faces away on British and Irish Lions duty the trip is being used to blood in youngsters with 11 uncapped players included in interim Wales coach Robin McBryde's 32-man training squad.
And Jones is urging the new guard to make the most of the opportunity that has been handed to them.
"This summer is a great opportunity for players to make their mark with Wales," said Jones.
"It's a chance for us to find out what the players are about, see some on the international stage for the first time and see some step up and lead the team.
"The World Cup is only two years away and players need to start putting their mark down now.
"If you look back at the 2009 tour, players came through, put their hands up and look where they are now. This is a huge opportunity for this squad.
"It's a chance for the players to work closely with international coaches, experience an overseas tour, see how they cope with it and test themselves on this stage."
