New father James Anderson is confident he will be physically and mentally fresh, after two trips round the world in the last week, to lead England's attack in the third Ashes Test.

Anderson arrived in Perth on Monday afternoon after the return leg of his globe-trotting journey to witness the birth of his second child, Ruby.

He was given permission by the England management to fly home while his team-mates were playing against Victoria in Melbourne, and Ruby was born last Friday.

"I didn't try to acclimatise back to English conditions, just tried to stay on Australian time. I didn't get into a sleep routine in England. I think I've done that well," said Anderson.

The fast bowler was due to have his first practice on Tuesday afternoon back with a team who can retain the Ashes with victory at the WACA, albeit a ground where previous English tourists have had precious little success.

"I've got two days of preparation now before the first Test," he said.

"I don't see why they're not going to go well, and I feel fresh, and probably happy for the rest from bowling after a tough first two Tests."

Anderson appears grateful to his employers for allowing him to return home temporarily, and accepts the job he does means he inevitably has to compromise on time spent with his family - even during life-changing times.

"It was obviously nice to go back for a few days and be there for the birth," he said.

"In an ideal world, I probably would have stayed a bit longer.

"But the nature of my job is I've got to be here and try to perform at my best for England."
