If it were me, I'd start her in 2010.

If she starts next year she will be way younger than the other kids and they may not even accept her anyway with the age guidelines they have. If you think she is ready though, you could always ring the school or visit and speak to the principal or whoever and get their advice. My birthday is in June and I started the year I turned 5. Even though I was able to do all the things they thought I should be able to do to be in school, they still didnt want me to start that year, purely because of my age... age and Lily would be 6 months younger than I was. In the end my mum pestered them and they took me.
