Oh, and I just checked the AO website *duh* and it says:
The Main Draw will be released on Sunday 15 January and play begins Monday 16 January, 2006. The Australian Open Website will have full draw sheets from the five main draw tournaments, the four junior tournaments and the wheelchair Classic 8s. These pages display completed match scores and the progression of the players in each event (Men's Singles, Women's Singles, etc.) and allow you to view the next and previous round match-ups (where available).
The DAY BEFORE? Surely that's inaccurate.
