BRISBANE - What birthday present do you give a kid who already has the run of a zoo?

If you're Bindi Irwin's mum, you make her a keeper at the family's world-famous Australia Zoo.

Bindi celebrated her ninth birthday in rock star-style at the wildlife park on Queensland's Sunshine Coast.

Her favourite singers and "best friends in the whole world" The Veronicas helped celebrate the big event, rocking out at the Crocoseum with thousands of pint-sized fans.

Terri Irwin said she had given her daughter a hand-held walkie talkie for her birthday, making the youngster an official Australia Zoo staff member.
