At the risk of making broad generalisations about a diocese as big and diverse as Sydney...
What might be helpful to understand is that there are two orders of ministry, those with incumbency licenses and those without. That is the reality on the ground in Sydney. Trying to fit current reality in Sydney into the three orders of ministry is like trying to fit a square peg in a round hole.
Following on from what Jenny noted the official position is that women can anything except hold an incumbency licence and consequently the things that only priests can do. (Because anglican priesthood has been tied to incumbency) The real issue is not what only ordained priests can do but what only incumbents can do. Administration of the sacraments is not widely considered an act that can be limited to the holder of an incumbents licence. Remember the issue has never been ordination of women to the priesthood - priesthood is a catholic concept. The issue has always been female headship in church.
Regarding women preaching to mixed congregations, opinions on that are as big and diverse as Sydney is.
Jereth, I think you are right in saying that Sydney tends towards a more baptist understanding of sacraments. To answer your question on Sydney communion liturgies. Yes they do have them and you can find them here:
