Inception has made it a hat trick of weeks at the top of the Australian box office.
Christopher Nolan's epic sci-fi thriller has been one of the critical and commercial hits of the summer and the movie grossed a further $4.1 million to comfortably hold off the challenge from new entry Step Up 3D.
The third Step Up movie to hit the big screen had to settle for second spot as it took $3.1 million this weekend to be the highest new entry at number two.
The movie follows a tight-knit group of New York City street dancers, including Luke (Malambri) and Natalie (Vinson), team up with NYU freshman Moose (Sevani), and find themselves pitted against the world's best hip hop dancers in a high-stakes showdown that will change their lives forever.
There was a once place drop for Killers, Knight & Day and Toy Story 3 as they finished the week at three, four and five to round of this week's top five.
There was also a single place drop for The Twilight Saga: Eclipse and The Karate Kid at six and seven. At number eight was the second new entry of the week in the for of The Special Relationship.
Nine was also a new entry as Ewan McGregor and Pierce Brosnan's latest movie The Ghost Writer had a disappointing opening weekend. Grown Ups was this week's biggest faller as it dropped two places from eight to ten.
