Assuming this continues the way it has been going for the last three days, when was the last time Australia was beaten this convincingly in a test? Not trying to have a big doom and gloom whinge about the state of Australian cricket or anything, I'm just interested.
Looking back, Australia lost a test in Perth recently that was fairly comfortable but no smashing. They managed to come back and make both the losses in the 05 Ashes fairly close tests. Last loss before that was in the previous series in India, which was by 13 runs. Before that, the drawn home series against India, which was four wickets, then the West Indies record chase, three wickets. Both fairly close games. The 02/03 Ashes had a fairly comfortable loss in the 5th test, only possible competition I can see in the decade so far.
Back in the late 90s there's a pretty bad loss to Sri Lanka in the game where Waugh and Gillespie ran into each other in the 1-0 lost series, and just before that in the '98 India tour there's an innings defeat, which might be the last time Australia got totally hammered in a game of cricket across five days. Shows the magnitude of the Indian achievement here if they go on with it.
