The RPL is equivalent to the RA-Aus pilot certificate, which is issued by Recreational Aviation Australia.
The PPL allows private pilots to operate single engine aircraft in VFR conditions throughout all Australian airspace classes in daylight.
[2] PPL holders may operate Australian registered aircraft in foreign airspace, subject to the regulations of the relevant government aviation authorities.
[6] Holders of a foreign (ICAO) pilot licence may fly temporarily in Australia for up to 12 months using a Certificate of Validation.
