Thank you for reaching out, your traveling dates can definitely work.
I must say that I love australians as I have quite a few friends from there and they always have a positive and happy energy . I am originally from Colombia and we are also very happy people. I've been in NYC for over 13 years so that also makes me a New Yorker. I will gladly give you tips on anything i can help you with.
Your arrival time should be fine, you can just call me once you arrive at the airport or feel free to call me prior to it if you'd like to arrange the meeting time.
My number is (phone number hidden)
Safe travels and see you soon in NYC!! :)
