Aus are the best international team, that is without doubt - what is infuriating though is that they also arm themselves with every advantage to extend this dominance - as GBT mentions above.
Teams with various advantages can use them to gain wins - France in 1978, the first test in the last ashes series, some of the recent WCC in teh UK are examples.
The July tests can only result in wipeouts as the scores of 52-0, 64-10 and 48-6 show.
The country v city and three SOO matches are preparation beyond the wildest dreams of any other country, add to this home advantage and a home ref and there is no other result.
I'm glad the mid season games have been ditched - a tri series is the only way forward. (although I am sad to see the postponment od ashes series and WC).
