Why an observer in the southern hemisphere cannot see the star polaris?
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.

That refers to its actual brightness, not to how we see it. The apparent brightness depends on the real ("absolute") brightness, but also on the distance.
Why isn't Polaris the brightest star?
How bright a star appears depends on how bright it is and how far away it is. While, on the whole Polaris is a very bright star it is also very far away, at least 350 light years, which makes it appear dimmer. The brightest star in the night sky is Sirius, one of the closest stars to Earth at only 8.6 light years. The brightest star overall, as viewed from Earth, is the sun, which is a quarter of a million times closer to us than the next nearest star.

Is polaris a particularly bright star?
No. In fact, Polaris is the dimmest of the 57 stars commonly used for celestial navigation. Except for the happy coincidence that Polaris perches almost precisely above the Earth's north pole, nobody would think anything about it. In fact, we're fortunate that the skies around the north pole are bereft of bright stars. Polaris is relatively easy to find only because there are NO bright stars in that part of the sky.
