Warning : long winded post
We love our smartphones so much that when we discovered that the hotel had no working wifi, we popped into Chinatown to get a tourist sim card.
Thus for AUS 2 per day as opposed to AUS 25 per day at the hotel , we were able to access google maps so we didn't need to worry about getting lost.
When we finally reached the Opera House, the rainy weather was beginning to get under our skin. Quick nip into tourist shop selling these ghastly kangaroo paws, then out again to look for reasonably priced food to fill our tummy .
