London, June 7 (UNI) Australia reached 73/2 at lunch after being sent into bat under overcast conditions on the first day of the WTC final at the Oval on Wednesday.
Marnus Labuschagne (26) and Steve Smith (2) were in the middle at the break.
Opener Usman Khawaja (0) lost his wicket early after edging one angling into him off Mohammad Siraj to Srikar Bharat behind the stumps.

The impressive Siraj was very well supported by Mohammad Shami at the other end as India fished for more wickets, with the swinging ball troubling the Aussie batsmen.
Labuschagne survived a couple of confident LBW reviews and took a couple of stings on his fingers off some deliveries that snorted up hitting on his gloves.
David Warner and Labuschagne played a waiting game, and once they saw the new ball off, the opener launched an attack on first-change bowler pacer Umesh Yadav and staved off the pressure building on them.
The dangerous Warner (40) fell minutes before the lunch break, and India seemed back on track. His partnership of 69 runs with Labuschagne for the second wicket was threatening to put Australia in control early in the game.
Warner was caught by Bharat behind the stumps off fourth seamer Shardul Thakur. After lunch, India have theirtask cut out. UNI BDN SSP
