In her first grass-court tournament, the Eastbourne International, she won through to the third round, only to be beaten in three tight sets by Nadia Petrova.

Since her daughter was starting school in Austria in September 2007, Bammer decided to plan her season so that she would never be away from home for more than a month at any one time.

She then got her first win over Nadia Petrova in the first round of the Sydney International in straight sets, 7–5, 6–3, before losing to Katarina Srebotnik.

At the Qatar Open, Bammer made her first ever Tier-I quarterfinal and scored the biggest win of her career over world No.
