The Australians Schools sides have been tweaked ahead of next week's Tri-nations series with Tonga and New Zealand.
Archer Holz, Dylan Saunders and JP Tominiko have been brought into the camp as replacements after impressing in their school seasons.
Australia takes on New Zealand and Tonga in Brisbane next week as part of an annual international series.
The Aussie Schools side will also travel to the UK at the end of the year for a tour.
Australian Schools coach Andrew Moloney said the addition of some new faces had generated some extra competition in the team.
"We’ve been impressed with the intensity and effort of both squads during the camp," he said.
“Having invited new players into the group we have seen the whole squad work even harder knowing that spots are still up for grabs, as ultimately they all want to represent their country at the highest level.
“Our focus this week is our first game against Tonga and I know the team is certainly excited and looking forward to the challenge that this game presents.
“The opportunity to play at Ballymore later in the week, off the back of the Junior Gold Cup is going to provide a fantastic atmosphere for both sides.”
Every match of the competition will be LIVE and FREE on RUGBY.com.au.
