The big difference between the hemispheres is what is often called "the seasons". the dec-jan period is when we have long hours of daylight and long periods of twilight. There are lots of lists for northern hemisphere folk telling the best orer to do a messier marathon, but just try it for a southern location such as Sydney. Stellarium is perfect for this demo. you soon see that a marathon in dec or jan just won't work.
