He stands near the opening of the border, north-west of the Al Kharid Mine, which used to allow players to go into the Al-Kharid region without paying the 10 coin toll. He can be found to the east of Rat Burgiss, the character who you talk to in order to start the easy Varrock Tasks. Ali Morrisane has stationed him here because it is a major crossroads in Misthalanian and Kharidian commerce, used primarily by Lumbridge, Varrock, and Al-Kharid to trade and travel. Ali's chat head was one of the first chat heads that was rendered in high detail in RuneScape 2.
