England won the toss and chose to bat first.
Australia took an early wicket (Cook, for 10) and followed up with two more in the morning session, to go to lunch slightly in front with England at 3 for 97.
After lunch, England's batting stalwarts, Pietersen and Collingwood, built a slow but steady partnership and took the score on to 228, before being dismissed close together after tea.
Prior and Flintoff built a new, faster-scoring partnership, and took the score from (five for) 241 to 327 before both were bowled by Siddle with the second new ball.
Anderson and Broad saw out the remaining play for a handful of runs.
Day one saw honours roughly even with England on 7 for 336. They should be able to press on to 350 or 370 or so tomorrow, which is a thoroughly respectable score - not enormous, but Australia will have to beat it by a solid margin because they will be batting fourth, and the pitch is expected to become more difficult as time goes on. Further, the pitch is already providing some grip and turn for the spin bowlers, and England is stronger in that department that Australia, and the pitch will only get better for them in this regard.
