This was the eighth time out of 13 innings that Australia haven't been able to post a score of 300 or more runs in an innings, in the last year. This does not include Michael Clarke's declaration against India at Hyderabad, when Australia were 237 for 9. Among the top Test teams, again, only New Zealand have done worse.
Australia's first four batsmen in their line-up have contributed, largely, to their team's batting woes. They have not been allowed to spend much time at the crease by the opposition bowlers. Their top order has faced 52, on average, balls per batsman-innings.
The top four batsmen of only West Indies and Pakistan have hung around for fewer deliveries in Tests in 2013.

Not surprising then, their top four batsmen are yet to score a hundred from 52 innings in 2013. They are the only Test team not to have a single hundred from their top four batsmen. They are also the team with most ducks - seven - from batsmen at batting at No.1 to No.4
