never mind mate..... next time.... im back home again now!
Ended up using a combination of the recommendations.
Booked a "towncar" to pick us up from the airport to drummoyne, then we got a bus back to the city, then train back to the airport...now im back with a happy wife and a full glass!
I can recomend the towncar option .really good.
Thanks everyone im in the good books tonite
