yeah, I think from between the Pakistan series of 83/84 and the '89 Ashes (5 1/2 year period), we only won ONE test series (against New Zealand in 1987). That was during the period where the Australian side was decimated by the Rebel Tours (cricket's equivalent of the Super League War post World Series era). It took us a while to recover from that and build the depth in the side back up again.
But, regarding the the last time we lost 3 in a row (vs West Indies nearly 20 years ago), fair enough, we were up against a champion side of Richards, Ambrose, Marshall, Walsh etc. They were way too good for us.
In Ponting's case, it's very different. If you think about the losses, the one vs Pakistan at Headingley, we got bundled out in the 80s for the 1st innings (again, I think that was the lowest 1st innnings total by an Australian side for MANY years. I don't exactly remember when, have to do some research, but in my time following cricket, I don't ever remember sides during the Mark Taylor or Steve Waugh era achieving this feat), and as a result, we lose out first test to Pakistan since 1995. And then the last time, we should have NEVER lost that when we had India 8 down. Yes, Bollinger going off had a big impact and I believe we would've won if he stayed on bowling, but even with Bollinger off, Ponting's tactics were just like Mohammad Yousuf's in the 2nd test at the SCG earlier this year. Everytime Laxman (our nemesis) was on strike, Australia never looked like getting him out. You're not going to win test matches with all men out on the boundary and it was Ponting's poor captaincy tactics which completely took the pressure of India and allowed Laxman/Sharma to slowly by slowly edge their way towards victory.
