>Which flat model? The flat model can easily have northern and southern stars, they are intimately linked to the earth's magnetic field.
All flat earth models.

Below about 30 degrees south the circumpolar stars never set below the horizon at night, which means they are visible from all locations at night at the same time.
These stars can also be used to find south at night, particularly the Southern Cross.

By all flat earth models, south is just away from north, the center of the flat earth map, however people in South America, South Africa, Australia and New Zealand can all observe the Southern Cross at night and use it to find "south". By the flat earth models these would all be different directions, yet they observe the same stars and can use those stars for navigation.
