Longitudes makes the difference. NY is at #74^o# W and Sydney's longitude is #151^o# E, making a difference of #225^o#. The time difference is 16 hours in advance, for Sydney.

Explanation:

Night is day for antipodal locations,

Of course, night Full Moon could possibly seen at the same time, as daytime Full Moon, at diametrically opposite locations, depending upon Moon-rise and Moon-set timings for Full Moon, at each location

Longitude difference of #15^o# creates a time-difference of 1 hour.
