The Magellanic Stream and Leading Arm which originated from the Magellanic Clouds are spectacular gaseous features. They extend for tens of kpcs and span for ~200 degree in the southern sky. The close proximity of the Magellanic Clouds to the Milky Way provides an excellent opportunity to study interacting galaxy system. I utilized the data from Galactic All-Sky Survey (GASS) and ATCA high-resolution Magellanic Stream survey to study the properties of high velocity clouds that presumbly associated with the Magellanic Stream and Leading Arm. Morphological classification is given for these HVCs and HVCs catalogs in this vicinity are presented. I will also present the the newly discovered population of clouds
that forms the LA IV and a new diffuse bridge-like
feature connecting the LA II and III complexes.
