Actor Hugh Jackman says that he had to work hard to perfect his native Australian accent for new film `Chappie`.

Jackman has teamed up with director Neill Blomkamp for the first time for the film, in which he takes on a role that required a stronger Australian accent from the actor.

And the actor has revealed that he had to brush up on some of the phrases that Blomkamp kept coming up with for his character, reports femalefirst.co.uk.

Speaking to the Press Association, the 46-year-old actor said: "I had to practise it because it was way stronger than my natural accent."

"He used a lot of phrases, and I had to end up Googling the slang. Neill was coming up with some really cool sayings. I was trying to think of more, so I ended up Googling some of them,` he added.

`Chappie` is the third feature film for Blomkamp, after the success of `District 9`.
