The depiction of the compass rose on a navigational chart in the Southern Domestic Airspace (SDA) is shown as magnetic. This is crucial for pilots as it directly relates to how navigational aids and aircraft instruments operate within the airspace. Magnetic headings are essential for aligning aircraft navigation systems and for ensuring pilots can accurately interpret the magnetic directions necessary for flight operations.

In the Southern Domestic Airspace, utilizing magnetic headings is advantageous as they are more relevant to the local terrain and provide immediate reference points during flight. As the earth's magnetic field does not perfectly align with geographical true north, understanding and using the magnetic values depicted on charts are essential for effective navigation.

The distinction between true and magnetic depictions is significant in the navigation realm. True north is constant and does not change, while magnetic north can vary depending on the geographical location and the magnetic declination in that area. Therefore, charts in the Southern Domestic Airspace, which utilize magnetic depictions, facilitate more practical navigation for pilots flying within this specific airspace.

The other options concerning the Northern Domestic Airspace and true depiction do not apply in this context, as their focus diverges from the specifics of the Southern Domestic Airspace navigation.
