Well if the group I was with 120 or so is anything to go by, we had plenty of opportunity to share our faith with the locals in Sydney.
I personally had quite a few one on one's with people some Christian and some not.
But my impression was that of those who were confronted on their faith, most did not take a backward step, in fact they took the opportunities to educate as they occurred.
The Holy Spirit was working wonders in Sydney!
