The Regulations create obligations and potential enforcement exposure for identifiable categories of persons and entities. The primary affected parties are:
- Aircraft operators: defined in the instrument and required to observe conditions and restrictions imposed under determinations, declarations and directions (definition and the offence provisions in regulation 16). They must monitor AIP/NOTAM publications to know when airspace classifications, special use designations, or service variances apply (regulations 5(3), 7(1), 9(1), 11(3)).
- Aircraft owners: expressly subject to CASA’s information notices requiring provision of documentation or information in their possession, custody or control when reasonably necessary for reviews (regulation 14(1)-(3)). Failure to comply attracts a 50 penalty unit sanction and strict liability (regulation 14(3)-(4)).
- Aerodrome operators: defined and specifically named as persons who may be required to provide information under regulation 14. Aerodrome operators are also affected by determinations about controlled aerodromes (regulation 5(1)(e)) and by CASA’s publication of particulars of ATS for controlled aerodromes (regulation 9(1)).
- Providers of air traffic services: defined and included as both recipients of information notices (regulation 14) and potential delegates of CASA’s functions and powers (regulation 13(1A), 13(3)). Approved providers can be delegated functions and tasks to give directions or make determinations under specified regulations (regulation 13).
- Personnel of approved ATS providers and the Australian Defence Force (ADF): the ADF is explicitly mentioned within the definition of approved provider for delegation purposes (regulation 13(3)(b)). Personnel of approved providers can receive delegated authority to exercise functions or powers under the specified regulations (regulation 13(1A)(c)).
- CASA: responsible for making determinations, declarations and designations; for publishing required particulars in AIP/NOTAM; for issuing information notices and conducting statutory reviews every five years; and for managing delegated powers (regulations 4, 5, 6, 7, 9, 10, 13, 15).
- The Minister and ICAO: the Minister may request reports of CASA’s statutory reviews (regulation 15(4)); CASA must notify ICAO and member States of declarations of prohibited or restricted areas that are to have effect for three months or longer, including location and boundaries (regulation 7(4)).
Who pays: regulated parties (aircraft operators, owners, aerodrome operators and ATS providers) bear compliance costs (monitoring AIP/NOTAMs, adapting routes, adjusting operations to meet published conditions), respond to CASA information notices within 28 days, and face penalties of 50 penalty units for non‑compliance (regulations 14 and 16). CASA bears the administrative cost of making determinations, publishing in the AIP/NOTAM, conducting five‑year reviews and preparing reports (regulations 5(3), 7(1), 15(2)-(3)). Approved ATS providers may bear additional duties if delegated functions are vested in them (regulation 13).
Decision‑makers: CASA is the primary decision‑maker for designations, declarations and determinations (regulations 5, 6, 8, 11). CASA may delegate to specified staff, approved providers or their personnel and to the ADF for some functions (regulation 13). The instrument expressly leaves certain matters to CASA’s opinion (e.g., military necessity for prohibited areas, safety/environment/security for restricted areas, activities dangerous to flight for danger areas) (regulation 6(2)-(5B)).
Information flows: CASA requires regulated parties to supply information reasonably necessary for the statutory five‑year reviews (regulation 14(2)-(3)). CASA publishes operational particulars that directly alter what operators must do or how they operate (regulation 9(1)-(3), regulation 7(2)-(3)). Publication in AIP/NOTAM is the trigger that creates notice and legal effect (regulation 5(3), regulation 7(1)).
