Will a full moon occurring in New York, USA be seen at the same time in Sydney, Australia? Or does the area of the planet make full moon viewing different for different regions?

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.


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.
