5 Direction for temporary restricted areas outside Australian territory

  Australian aircraft

  If an instrument (a TRA instrument):

(a) issued by OAR; and

(b) expressed as made under either or both of regulations 6 and 9 of the AsR;

  purports to create 1 or more temporary restricted areas in Australian-administered airspace outside Australian territory (an external TRA), then the operator of an Australian aircraft is directed to comply with the requirements of the TRA instrument and its conditions (if any) as if they applied to the operator while the aircraft is in the external TRA.

Note 1   This section applies whether or not the TRA instrument also creates temporary restricted areas inside Australian territory. Such instruments for temporary areas inside Australian territory are separately valid and enforceable.

Note 2   It is an offence under regulation 11.255 of CASR to contravene the direction in section 5.

Note 3   Foreign registered aircraft

There is no requirement for a separate subsection to deal with foreign registered aircraft.

If a TRA instrument creates a TRA inside Australian territory, then the instrument applies to foreign registered aircraft by force of regulation 6 of the AsR.

If a TRA instrument purports to create 1 or more temporary restricted areas in Australianadministered airspace outside Australian territory (an external TRA), then under the Chicago Convention, as applied by section 11 of the Civil Aviation Act 1988, this direction instrument has no application to foreign registered aircraft. For an external TRA, as defined in this direction instrument, the operator of a foreign registered aircraft is not required to comply with the requirements (if any) of the instrument while the aircraft is in the external TRA. However, CASA strongly recommends that the operators of such foreign aircraft should comply in the interests of aviation safety, given that the relevant reasons for the declaration of the external TRA may constitute a threat to aviation safety.

6 Direction – Airservices Australia – Air Traffic and Aeronautical Information Services

  For aircraft operating in, or in the airspace adjacent to, an external TRA of a kind mentioned in section 5, Airservices Australia is directed that, as far as practical, it must provide ATS and aeronautical information services in accordance with the conditions (if any) expressed in the TRA instrument that is for the area, as if the area were a declared restricted area.
