There may be some set screws on each or any side of that circular compass.
Usually to compensate for where you have to place it on your ship to correct
any magnetic conflict.

Try to place it on your ship where there will be no interference but that
may seem impossible. Install it where you like, which may cause this
interference and then adjust those screws (if it has them) to the true north
and that should take care of it.
Could depend on the southern or northern hemisphere compass. Where was the
compass originally purchased for? Some compasses have weights on the
opposite leg to the north in order to eliminate it from digging into to its
own board. For example, if you have a northern hemisphere compass, there
will be a little weight on the needle, this prevents it from digging in or
aiming right at true north (through the earth). But if you take that same
compass down to Australia, it will dig in and not be usable.
But in reality, when you go down to Australia, you are actually going up. In
relative prospective, Australia is actually on the top of the world, not
like the maps you are used to in grade school.
