Pat Cummins digs one in and gets the breakthrough for the Australians, with Tim Paine taking a simple catch behind.
Despite an audacious attempt at a drive first ball, Stoneman looked relatively assured at the crease. He hit two on-drives for four - something the hosts wouldn't have minded so early in his innings.
It took 29 balls for England's openers to hit a boundary, or a scoring shot more than a single for that matter. They've been watchful, until Stoneman's slip-up.
The sun is shining after a dull morning - the perfect temperature for batting. It's a pretty full house at the SCG today and no doubt a few punters would have spent the morning session at the bar making good use of their time.
