In short
Short answer: the Commercial 3 Zone (C3Z) is a Victorian planning zone set out in clause 34.03 of the Victoria Planning Provisions and applied to land through each council's planning scheme. In the clause's own words, its first purpose is: “To provide for a range of industrial, commercial, office and other employment generating uses which support the mixed-use employment function of the area”.

A zone sets the main purpose of the land and what can be built on it; every Victorian lot has one.
What it typically means for a buyer (Delora editorial, not legal advice): A mixed employment zone for industry, offices and services, with only limited housing allowed.
