I believe I read somewhere that Australia have decided they want a break from internationals this time next year. If there is something it will probably be NZ in the northern hemisphere with a rumoured return of a GB test series. So Samoa are going to have the momentum stifled if that is the case but I really do think Oz may have a real struggle with them next week.
If Aus want to sit it out id be more than happy for Samoa to take their place in the NH version. Might show them the game doesnt revolve around them
