One can see why Comet C/2024 G3 (ATLAS) will be difficult to observe from the northern hemisphere, given its location relative to the Sun as seen from a vantage point in the northern hemisphere.
Ideally, you want the comet to be located sufficiently above or below the Sun, but in the case of New York, it is located just slightly above the Sun for a few days and to the side after that.
Sydney OTOH has a much favorable view of the comet as seen below.
