Alexandra represented Australia at the 2000 Olympics. Then won a team all-around gold medal in the 2002 Commonwealth Games as well as a silver medal in the vault.
She retired at age 18. A great career.
Bored one day, age 19, she decided to try diving.
How did that work out for her?
The idea of diving—something she had never done before—intrigued Croak. It wasn’t that different from gymnastics except, as Croak pointed out, that divers fall on their head instead of their feet. …
“It wasn’t that tough of a transition. [Diving is] a lot less demanding on your body.†…
First she was selected to compete at the Commonwealth Games in Melbourne. And then, after just two weeks to prepare for an event she had never competed in—the synchronised 10-metre dive—Croak and 13-year-old sensation Melissa Wu finished second in the event behind much more experienced Australians Loudy Tourky and Chantelle Newbery. …
Not only did Croak claim a silver medal from the competition. She also became the first Australian woman to compete at the Commonwealth Games in two sports.
She’s just picked up another synchro medal at a World Cup meet in Brisbane.
