I can tell you how the rounds worked in my area last year but I cant tell you if its the same everywhere and this year....So on allocation day you receive your offer. You have a choice of accepting or declining the place. You really ought to accept the place even if you don't want it because if you decline it you are left with no place at all and wont be given preference to get another school you want. Once you accept the offer, your child will also be placed onto the continued interest lists for any higher ranked schools that you didn't get and that you are still willing to hold out for. As far I can remember this is automatic, and if you don't want to stay on the continued interest lists because you decide you are happy with your offer you need to contact the admissions team for them to remove you from continued interest list. Then in a few weeks they do a first round of continued interest, basically a reshuffle is worked out based on everyone who decides to accept/decline offers etc and what spaces have opened up are then given based on the same criteria as allocation day. Then if you still don't gain a place at your higher ranked school you can stay on the continued interest list again. Then they do a second and final round in around another month. Whilst you are on continued interest you can also lodge your appeal, get all this prepared just in case continued interest doesn't go your way. If I am incorrect in any of this information, im sure Tiggytape or Prhbridge will step in. As I say, we got the one school we really didn't want, we waited on continued interest and lodged an appeal. Continued interest round 1 came and went with no luck, but round 2 we made it! So, it is definitely worth being on those lists if you aren't happy with your given school.
