Keary's addition to the squad sees the Roosters with the most Club representatives in the Australian side, with Boyd Cordner captaining the side that also includes Jack Gibson Medalist James Tedesco and Latrell Mitchell.
The Kangaroos will face off against Tonga and the Kiwis in upcoming test matches later in October.
