High tea would be ace! Are you wanting themes, as in if you decide to stay in and do something or ideas for where to go? If you are going out I know in Melbourne there is soemthign along the lines of a chocolate tour through the city - Sydney probably do something similar!? At the end of the day it is a celebration for you and your new bubby with girls you love! You could also do a pamper day where you go to a day spa and all have pedicures or massages or something? Many cater for that sort of thing and may even include lunch etc.
