Okay but how does Aussie!Wild use vegemite as a weapon? Does he throw the container at people, fling globs of it at his adversaries' mouths or eyes, force feed...?
Flinging globs off of spoons is one option. I believe the texture of vegemite would be a pain in the ass to get out of one's hair.
Serving repeatedly for breakfast and lunch can help wear down his housemates so that he can get his way in arguments over things like what to watch on movie night or what game tournament should be next.
Force-feeding during interrogation is always an option.
Spreading a thin layer in front of the door or at the top of the stairs is a viable home defense method in situations like the home invasion.
Jars of vegemite make an acceptable projectile at the right velocity.
