Sigma Octantis is sometimes called the South Star.
North star is the polar star, not the pole star.The North Star is the pole star; it is diredtly above the North pole and is called Polaris. A polar star is a star in close proximity to the polar region such as Sigma Octantis, the Southern star which is close to but not directly over the South pole.
North star, or Polaris, is the name of a bright star that is CURRENTLY near the celestial north pole. Since the position of the north pole will change in the future, Polaris will still be called Polaris, but it will no longer be the north star.
Polaris, the North Star, is located near the North Celestial Pole which is visible only from the Northern Hemisphere. In the Southern Hemisphere, there is no bright star close to the South Celestial Pole like Polaris because the South Celestial Pole does not have a similarly positioned bright star. Therefore, observers in the Southern Hemisphere cannot see Polaris due to its location in the sky.
No, Polaris would not be overhead if you were at the South Pole. The North Star -- Polaris -- is not visible from the Southern Hemisphere.
No, people in the southern hemisphere cannot use the North Star (Polaris) for navigation because it is located directly over the North Pole. Instead, they use the Southern Cross (Crux) constellation to find south.
The pole star lies above the axis of rotation of the earth, hence for a person in the northern hemishere the pole star will show the north.But for a person in ,say australia the star may not be visible due th the earths curvature.
North StarThe name of the pole star is polaris.Polaris, also called the "North Star".

Unlike the North Pole, where the "North Star" Polaris is within a half-degree of being exactly north, there is no "South Star"; there are no naked-eye visible stars close to the South Pole. About the closest you can find is the Southern Cross, which points to the south pole without being right over it.
