Australia won the toss, batted and jumped out of the blocks on day 1, scoring 1/109 (Langer 68*, Ponting 11*) from 25 overs at lunch.
Cricinfo described the first ball thus:
Harmison's first delivery was a moment to rank alongside Phil DeFreitas's long-hop to Michael Slater on this ground way back in 1994-95. Then, as now, it pricked the bubble of anticipation for a capacity crowd, and provided Langer in particular, who was given such a working-over on the opening morning of the 2005 series, the ideal sighter to settle his nerves.
And it didn't get much better after this, at least from Steve Harmison's perspective. His figures at lunch: 6 - 0 - 37 - 0.
