Khawaja whips Siraj off his pads to deep square leg for a single to raise the 50-run stand for the second wicket.
Labuschagne taps the next ball on the off-side for another run before his partner ducks under a short ball and does the same last ball.
Just two overs for Reddy before Jadeja comes back into the attack. Labuschagne is beaten as he looks to play the cut shot as the spinner gets some extra bounce before he confidently defends the next.
The right-hander carefully plays out the rest of the over as Jadeja sticks to a good line just outside the off-stump for a maiden over.
Australia are 140/1 in 40 overs with Khawaja on 53 and Labuschagne on 23. They have scored 28 runs in 15 overs since lunch as India's bowlers have looked to build pressure by drying up the runs.
