What does KHA mean in Australian?

Kha

Kha or Ha is a letter of the Cyrillic script. It looks the same as the Latin letter X, in both uppercase and lowercase, both roman and italic forms, and was derived from the Greek letter Chi, which also bears a resemblance to both the Latin X and Kha. It commonly represents the voiceless velar fricative, like the Scottish pronunciation of ⟨ch⟩ in "loch". Kha is romanized as ⟨kh⟩.
