This is a huge mistake by Jelena. She played extremely well this fall and the OZ would be a tournament she could excel at. While she has had problems with the Australian Tennis Federation in the past, she needs to put it behind her. A good example of someone who put the past behind her was Hingis at Roland Garros. After a disasterous 99 final, Hingis went on the play in the doubles final the next day and came back the next year to play singles and doubles with Pierce. By coming back, I think Hingis demonstrated that, despite her bad behavior, she is serious about her tennis and that she wants to win Roland Garros.
It's up to Dokic. It sounds like she is still controlled by her dad. I hope that is not the case.
