Sydney:The fourth Ashes test sprung to life late on Day 1 after sweeping showers threatened to dampen the prospects of both teams for a positive start at the Sydney Cricket Ground.
After rain delays permitted only 21 completed overs in the opening two sessions, runs and wickets came more frequently in the final passage of play after tea as Australia reached 126-3 at stumps.
Steve Smith was unbeaten on six and Usman Khawaja was four not out when rain ended play for the day.
Veteran seamer Stuart Broad, recalled to the England team after being omitted for the third test in Melbourne, went someway to vindicating his selection by dismissing David Warner and generally appearing the most threatening bowler in the England attack.
Harris and Warner put on 50 for the first wicket before Broad made the breakthrough for England in the 21st over, teasing Warner onto the front foot and finding the edge which carried comfortably through to Zak Crawley at second slip for his 527th wicket in 151 matches.

Warner, who made 30 with six boundaries off his 72 balls, swiped his bat through the air in frustration at his dismissal and not capitalizing after making another good start to an innings in this series.
It was the 8th time Broad (1-34) has captured Warner's wicket over the past seven Ashes tests that the fast bowler has played in.
Marnus Labuschagne joined Harris at the crease, but four balls into the 22nd over showers swept back over the ground forcing the players from the field after only 9 overs of play in the middle session, much to the disappointment of the crowd of about 30,000.
