The Amateur Class Licence and Its Conditions
Australian amateur radio operates under a class licence made under the Radiocommunications Act 1992. Unlike an apparatus licence, a class licence is not issued to an individual: it authorises anyone who meets the stated conditions to operate, and the operator's authority comes from holding the relevant qualification together with an endorsed licence document from the ACMA. Understanding this distinction is the first concept a candidate must master.
Who and what is authorised
The class licence sets out the amateur service and amateur satellite service purposes, permitted frequency bands, maximum transmitter output power, emission modes and bandwidths, and prohibitions. Amateur stations must not be used for commercial or financial gain, must not transmit music or entertainment, must not engage in communications the operator could reasonably make by other means, and must not cause interference to other services. The licence also imposes obligations about station identification, third-party traffic, and remote or automated operation.
Common traps
Questions frequently test whether a class licence is held by a person (it is not), whether a licensee may use any power on any band (power limits are band-specific), whether a Foundation licensee may build transmitters (they may not; only commercially manufactured equipment), and whether unlicensed third parties may speak over the air (only under supervision and within the conditions). Another trap is confusing the roles of the ACMA (regulator, issues licences and call signs) with the Australian Maritime College (examinations) and the peak bodies (non-regulatory).
Worked rule of thumb
Read every condition as a two-part test: what the licence permits, and what the operator must personally hold. For example, operating on 50 MHz requires both that the class licence permits that band and that the operator's licence level includes that band. If either limb fails, the operation is unlawful.
