Australia will be a decent test for all the NH teams. They're going on a Grand Slam tour and it is possible that they could lose 3 of the 4 games against the home nations.
Charles.. Aus aren't playing France this autumn. France get the Springboks and the All Blacks though... good test.
Fortunately, we're not playing South Africa this autumn. Because I can see no way in hell of beating them. We're more than capable of beating Australia. And if we continue to build on our good finish to the 6N, and the ABs continue to play very badly, then there's a slim chance we could beat them too. Maybe.
