The main circumpolar constellations, which cannot be seen from the Northern hemisphere are Carina, Centaurus (Centaur) and Crux (Southern Cross).
Carina is part of what used to be Argo Navis, a large ship, but has since been divided into three smaller constellations, Carina (the keel), Puppis (the poop deck) and Vela (the sails).
Hydra (Snake), Pavo (Peacock), Musca (Fly), Apus (Bird) and Chamaeleon are some smaller ones which might be mainly or exclusively visible in the South. Most of the other constellations can be seen at some time during the year from the Northern hemisphere, although countries far north may not see them.

52, and there is also 5 constellations on the Celestial equator, it is don`t class as northern or southern hemisphere constellations.

It can be seen every year, like all constellations can be. It is best viewed from the southern hemisphere.
Northern Hemisphere
No, but southern constellations visible in Australia can't be seen in the Northern Hemisphere, so it all balances out.
no
Some of them, yes. Constellations along the Zodiac can be seen from either hemisphere, but constellations well away from the celesial equator cannot be seen very far in the other hemisphere. For example, Ursa Major is not visible in Australia, and the Southern Cross is not visible in Europe or North America. Most of the "official" constellations were named by northern hemisphere astronomers, or European navigators sailing in southern waters. Look at how many southern hemisphere constellations have a nautical theme; the Telescope, the Octant, the Quadrant. Even Cetus, the Whale, was named by sailors, not people who LIVED there.

Northern Hemisphere
Too many to mention - there are about 88 officially recognized constellations and more than 2/3rds of them can be seen from the Northern Hemisphere.
No. One of the better known constellations in the northern hemisphere is the big dipper. People in the southern hemisphere can't see this. In the south the well known constellation is the southern cross, and you can't see this in the northern hemisphere.
It can be seen in the southern hemisphere, but is better seen in the northern hemisphere.
