Both sides were locked at 0-0 after 90 minutes in London, with Italy enjoying the better of the first half but Austria rattling Roberto Mancini’s side in the second period.
Chiesa opened scoring early in extra-time and another goal from Pessina set up a quarter-final against the winners of Sunday’s tie between Belgium and holders Portugal.
But there was still time for late drama when Austria’s Sasa Kalajdzic stooped to head the ball in at the near post from a corner with a little over five minutes to go but their frantic final efforts were in vain.
Austria had a chance to snatch the lead on the counter when Marko Arnautovic ran through on goal after muscling past Leonardo Bonucci, only to fire wildly over from the edge of the area.
Unfazed by that scare, Italy were immediately back on the attack.
Ciro Immobile was inches away from putting them ahead when the Lazio forward whipped an audacious 20-yard strike against the woodwork with Bachmann rooted to the spot.
Having emerged as Group A winners with a 100 per cent record after playing all three of their games in Rome, Italy were on the road for the first time in the tournament.
