Welcome to Canada, you don't know what you've been missing! :D You should have a better day in Halifax tomorrow, sunny with a high of 24. If you don't have plans yet, I recommend the Marine Museum and the Citadel, and if you like beer, skip Alexander Keiths and check out the Garrison Brewing Company right by the cruise terminal. :beer-mug:
Sorry, I just realized I was reading your post from yesterday, but hope you enjoyed your day in Halifax!
Have fun in Sydney and if you get a chance, make sure to check out the trails around Louisbourg.
