Glasgow's Ryan Grant, Robert Harley and Tom Ryder and Edinburgh backs Tom Brown and Tim Visser, who has scored 43 tries in 74 appearances for the Heineken Cup semi-finalists, are in line to make their international debuts.
Despite Scotland's dismal showing in this year's Six Nations where they finished last without a win, Robinson was not worried about the lack of experience in the squad.
"We've seen from the manner in which Edinburgh and Glasgow have finished the domestic season that there's confidence that we will be looking to build on," Robinson said in a statement on Wednesday.
"This is a tough tour for Scotland. We'll be playing against three attack-minded teams on their own turf, but it's an important opportunity to start the rebuilding process after a disappointing Six Nations."
Scotland play Australia on June 5 in Newcastle, Fiji on June 16 and Samoa the following Saturday.
