Wow, nice trip buddy! I've been to Sydney and I have really loved the place. I actually consider Australia to be one of the best places in the world to have a family as standard of living is very high, amazing weather, beaches, exotic culture etc - Sydney has it all + a decent nightlife for younger guys as well, not as good as some states in US or some countries in EU, but it has many other aspects, that you could fall in love. I love your helicopter trip ^^ It must have been an really amazing experience. I never did that, but before I die I will definitely have to. Cheers ^
HAPPY NEW YEAR...
