A definite YES, but they will be down side up.
So when you read the level, you have to lift the high end to centralise, whereas in the northern hemisphere (where the bubbles are made and calibrated), they work on the assumption that you raise the low end to achieve the same result.
Unless of course, you could get someone to recalibrate the bubble to work the opposite way around, and then it would save you a lot of confusion.
But you must mark the level as having a reverse acting bubble, as people that are used to working with a northern hemispherical bubble in the southern hemisphere, will become disorientated and it might cause them to become very unstable, as they won't know which end to lift up. They just might cause themselves an injury, as they try to lift both ends of the the machine at the same time.
You could buy yourself a neutral bubble, this comes with a self adhesive pad that holds the bubble firmly in the middle of the vial. But they seem to have a reputation of not being very good, as the machines always act funny when they have been set up with a neutral level, pointing to the fact that it might be the level at fault, or in the case of southern hemisphere operators, blown out of their mind on lousy beer.

Do we really need to go on with this discussion?
