RADIOCOMMUNICATIONS - AUSTRALIAN SPECTRUM PLAN - REG 1 Citation
1. This spectrum plan may be cited as the Radiocommunications - Australian Spectrum Plan.
RADIOCOMMUNICATIONS - AUSTRALIAN SPECTRUM PLAN - REG 2 General
2. (1) This document sets out the Radiocommunications - Australian Spectrum Plan, which divides the radio frequency spectrum into a number of bands and specifies the general purposes for which the bands may be used.
(2) The primary basis for the structure of this Spectrum Plan is the Table of Frequency Allocations contained in the Radio Regulations published by the International Telecommunication Union (ITU).
(3) In particular this Spectrum Plan is based on the Table in the Radio Regulations appropriate to ITU Region 3 with reference to the following chart:
(CHART OMITTED)
(4) In the chart in subclause (3):
(a) Region 1 includes the area limited on the east by line A and on the west by line B, excluding any of the territory of Iran which lies between these limits and including that part of the territory of Turkey and the Union of Soviet Socialist Republics lying outside of these limits, the territory of the Mongolian People's Republic, and the area to the north of the USSR which lies between lines A and C; and
(b) Region 2 includes the area limited on the east by line B and on the west by C; and
(c) Region 3 includes the area limited on the east by line C and on the west by line A, except the territories of Mongolian People's Republic, Turkey, the territory of the U.S.S.R. and the area to the north of the U.S.S.R. and also includes that part of the territority of Iran lying outside those limits.
(5) A full description of where the lines A,B and C are to be drawn on a map may be found in Nos. 396 to 399 of the Radio Regulations.
(6) Where the words "regions" or "regional" are without a capital "R" in the Radio Regulations or in this Spectrum Plan, they do not relate to the three Regions here defined for purposes of frequency allocation.
(7) A sub-Region is an area consisting of two or more countries in the same Region.
(8) The shaded part of the chart in subclause (3) represents the Tropical Zone as defined in Nos. 406 to 411 of the Radio Regulations.
(9) The "Tropical Zone" consists of:
(a) the whole of that area in Region 2 between the Tropics of Cancer and Capricorn; and
(b) the whole of that area in Regions 1 and 3 contained between the parallels 30 degrees North and 35 degrees South with the addition of:
(i) the area contained between the meridians 40 degrees East and
80 degrees East of Greenwich and the parallels 30 degrees North and 40 degrees North; and
(ii) that part of Libya north of parallel 30 degrees North.
(10) In Region 2, the Tropical Zone may be extended to parallel 33 degrees North, subject to special agreements between the countries concerned in that Region.
(NOTE: The operation of radiocommunications transmitters for non-broadcasting purposes is governed by the Radiocommunications Act 1983. As a general rule a person may not operate a radiocommunications transmitter for non-broadcasting purposes unless the Minister has granted a licence. The categories of licence which the Minister may grant are set out in the Radiocommunications (Licensing and General) Regulations made under the Act. However, certain non-broadcasting transmitters are exempt from licensing by regulation under section 22 of the Act.
In deciding whether to grant a licence the Minister is required to have regard to all matters that he considers relevant, including:
(a) whether or not:
(i) the applicant; or
(ii) each person specified by the applicant as a person to whom the
applicant, if successful in his application, proposes to give an authority under subsection 26(1);
is a qualified operator in relation to any licence that the Minister
may grant as a result of the application;
(b) the extent (if any) to which the purpose of the operation of
the transmitters specified by the applicant is a purpose that could reasonably, in all the circumstances, be effected by a means other than the proposed operation of the transmitters;
(c) whether or not the Minister is satisfied that the proposed
operation of the transmitters is in accordance with the appropriate frequency band plan;
(d) the effect on radiocommunications of the proposed operation of the
transmitters;
(e) whether or not the Minister is satisfied that the proposed
operation of the transmitters is not reasonably likely to cause death of, or injury to, persons, or loss of, or damage to, property;
(f) the policies specified in Division 1 of Part 3 of the
Telecommunications Act 1989.
Under subsection 7 (1) of the Act the Minister is also required to
have
regard to the International Telecommunication Convention and the ITU Radio Regulations.
Subsection 25 (1) of the Act sets out conditions to which a licence is subject. As well as particular conditions specified in subsection 25 (1), a licence is also subject to conditions prescribed by regulations or specified by the Minister in the licence.
Of particular importance is paragraph 25 (1) (a) which makes it a condition that the holder of the licence shall not operate, or permit the operation of, the transmitter except for a purpose specified in the licence, being a purpose not inconsistent with a purpose of a kind specified in the appropriate frequency band plan under subsection 19 (2) of the Act.)
RADIOCOMMUNICATIONS - AUSTRALIAN SPECTRUM PLAN - REG 3
Alternative Allocations
3. Australia may adopt alternative allocations to those specified in Article 8 of the Radio Regulations provided that:
(a) no harmful interference is caused to stations in other
countries
operating in accordance with the provisions of the International Telecommunication Convention and the ITU Radio Regulations; and
(b) the possibility of harmful interference from other stations
operating in accordance with the provisions of the International Telecommunication Convention and the ITU Radio Regulations is accepted.

RADIOCOMMUNICATIONS - AUSTRALIAN SPECTRUM PLAN - PART 2
PART 2 - STRUCTURE OF THE SPECTRUM PLAN
RADIOCOMMUNICATIONS - AUSTRALIAN SPECTRUM PLAN - REG 6
The Structure of the Plan etc
6. (1) In interpreting this Spectrum Plan:
(a) the table in Part 5 of this Spectrum Plan indicates in diagrammatic form the radio frequency spectrum from 9kHz to 400 GHz, which has been divided into frequency bands within which certain designated radiocommunications services may be operated (see Part 1 for the definitions of these services);
and
(b) bands are shown in increasing frequency order from 9 kHz to 400 GHz; and
(c) the range of frequencies covered by each page of the Table is shown above the heading, together with the unit of frequency (kHz, MHz or GHz); and
(NOTE: As Australia is a signatory to the International Telecommunication Convention, regard is taken of the provisions of the ITU Radio Regulations in the assignment of frequencies to radiocommunication services shown in Article 8 of the ITU Radio Regulations for Regions 1, 2 and 3 which are reproduced in Column 1 of the table.)
(d) the allocation to services in Australia is shown in Column 2 which is sub-divided into frequency bands; and
(e) each band is assigned a name which consists of two numbers in the top left hand corner of the box containing the band and the unit of frequency set out in the heading at the top of the table on the page containing the frequency band, for example, on the first page in Part 5 "9--14" is in the top left hand corner of the box and kilohertz is the unit of frequency at the top of the page and the name of this frequency band is the "9 to 14 kilohertz band"; and
(f) the actual frequencies contained in each band are those greater than the first number up to, and including the second number, for example, the frequencies contained in the band referred to in paragraph (e) are those above 9 kilohertz including, but not exceeding, 14 kilohertz; and
(g) within each band in each column:
(i) the boxes contain a list of radiocommunication services that may operate within that band; and
(ii) the order of listing of services in the table does not indicate relative priority within each category; and
(iii) the status of individual services (primary, secondary or permitted) is indicated by their being in either capitals, lower case, or between oblique strokes, respectively; and
(h) in the case where the name of a service is followed by an addition in parenthesis, that service allocation is restricted to the type of operation so indicated, for example, "FIXED-SATELLITE (earth-to-space)" limits transmitting stations in the fixed-satellite service to operation in the earth-to-satellite direction; and
(i) in addition, the name of a service may be followed by additional remarks, for example, "MOBILE except aeronautical mobile" limits the allocation to the land mobile and maritime mobile services, and excludes the aeronautical mobile service and "MOBILE except aeronautical mobile (R)" limits the allocation to the land mobile, maritime mobile and aeronautical mobile (OR) services, and excludes the aeronautical mobile (R) service; and
(j) in Column 1 there may be a number (eg "444") following the allocation to a service, or appearing at the bottom of the box and these numbers refer to
"footnotes" which are contained in Part 7 of this Spectrum Plan and have equivalent status to the entries shown in the Table; and
(k) the allocations to services in Column 2 generally follow the allocations to Region 3 shown in Article 8 of the Radio Regulations, and account has been taken of additional allocations and alternative allocations to the Region 3 Table applicable to Australia, with either a table or footnote entry as appropriate; and
(l) in addition to relevant ITU footnotes, particular Australian
footnotes
are shown in Column 2, prefixed by the letters "AUS", and footnotes with this prefix are defined in Part 6 of this Spectrum Plan and have equivalent status to the entries shown in Column 2 of the Table; and
(m) the footnote reference indicators which appear at the bottom of a particular box of the tables below the listed service or services apply to all services to which the band concerned is allocated; and
(n) the footnote reference indicators that appear to the right or indented and immediately below the name of a particular service apply only to that service.
(NOTE: Where footnotes from the Region 3 Table that are operative in Australia call for administrations to act in a particular manner (eg 444, 572 etc), the Australian Administration will have regard to these requirements.)
(2) Where column 2 of the Table in Part 5 or a footnote in that column allocates services to a frequency band which are different to the services allocated in that part of Column 1 of the Table or a footnote in that part which applies to the frequency band in Region 3, operation of the services allocated by Column 2 in Australia is constrained by:
(a) any restraints on the services specified in Column 2 or specified by a relevant footnote; and
(b) the requirement in Radio Regulation 342 that the services cause no harmful interference to services operating in accordance with the provisions of the International Telecommunication Convention and the Radio Regulations.
(3) Notwithstanding subclause (2), requirements for coordination or notification of services expressed in the Radio Regulations apply.
(4) For the purposes of the definitions of "medium frequency band" and "very high frequency band" in subsection 4 (1) of the Broadcasting Act 1942 and subsection 6B (3) of the Radio Licence Fees Act 1964:
(a) the band of frequencies above 300 kilohertz, up to and including 3000 kilohertz is designated as the medium frequency band; and
(b) the band of frequencies above 30 megahertz, up to and including 300 megahertz is designated as the very high frequency band.
RADIOCOMMUNICATIONS - AUSTRALIAN SPECTRUM PLAN - PART 3
PART 3 - CATEGORIES OF SERVICE AND ALLOCATIONS
RADIOCOMMUNICATIONS - AUSTRALIAN SPECTRUM PLAN - REG 7
Primary, Permitted and Secondary Services
7. (1) Where, in a box of the Table in Part 5 of this Spectrum Plan, a band is indicated as allocated to more than one service, such services are listed in the following order:
(a) services, the names of which are printed in "capitals" (example: FIXED) which are called "primary" services;
(b) services, the names of which are printed in "capitals between oblique strokes" (example: /RADIOLOCATION/) which are called "permitted" services;
(c) services, the names of which are printed in "normal characters" (example: Mobile) which are called "secondary" services.
(2) Additional remarks are printed in normal characters (example: MOBILE except aeronautical mobile).
(3) Permitted and primary services are of equal status, except that the primary service, as compared with the permitted service, has prior choice of frequencies.
(4) Stations of a secondary service are of a lower status than primary and permitted services.
(NOTE: Stations of a secondary service:
(a) shall not cause harmful interference to stations of primary or permitted services to which frequencies are already assigned, or to which frequencies may be assigned at a later date;
(b) cannot claim protection from harmful interference from stations of a primary or permitted service to which frequencies are already assigned, or may be assigned at a later date; and
(c) can claim protection, however, from harmful interference from stations of the same or other secondary service(s) to which frequencies may be assigned at a later date.)
(5) Where a band is indicated in a footnote of the Table as allocated to a service "on a secondary basis", or in an area smaller than a Region, or in a particular country, this is a secondary service.
(6) Where a band is indicated in a footnote of the Table as allocated to a service "on a primary basis", or "on a permitted basis" in an area smaller than a Region, or in a particular country, this is a primary service or a permitted service only in that area or country.
(7) If a frequency band is allocated to a service as a primary service, nothing in this Plan prevents the same type of service being allocated the same frequency band as a secondary service in a frequency band plan.
RADIOCOMMUNICATIONS - AUSTRALIAN SPECTRUM PLAN - REG 8
Additional Allocations
8. (1) Where a band is indicated in a footnote of the Table as "also allocated" to a service in an area smaller than a Region, or in a particular country, this is an additional allocation, i.e., an allocation which is added in this area or in this country to the service or services which are indicated in the Table.
(2) If the footnote does not include any restriction on the service or services concerned, apart from the restriction to operate only in a particular area or country, stations of this service or these services shall have equal status with stations of the other primary service or services indicated in the Table.
(NOTE: If restrictions are imposed on an additional allocation in addition to the restriction to operate only in a particular area or country, this is indicated in the footnote of the Table.)
RADIOCOMMUNICATIONS - AUSTRALIAN SPECTRUM PLAN - REG 9
Alternative Allocations
9. (1) Where a band is indicated in a footnote of the Table as "allocated" to one or more services in an area smaller than a Region, or in a particular country, this is an "alternative" allocation, i.e., an allocation which replaces, in that area or in that country, the allocation indicated in that Table.
(2) If the footnote does not include any restriction on stations of the service or services concerned, apart from the restriction to operate only in a particular area or country, these stations of such a service or services shall have equal status with stations of the primary service or services, indicated in the Table, to which the band is allocated in other areas or countries.
(NOTE: If restrictions are imposed on stations of a service to which an alternative allocation is made, in addition to the restrictions to operate only in a particular country or area, this is indicated in the footnote.)
RADIOCOMMUNICATIONS - AUSTRALIAN SPECTRUM PLAN - REG 10
Miscellaneous Provision
10. Except if otherwise specified in a footnote, the term "fixed service", where appearing in the Table, does not include systems using tropospheric scatter propagation.
(NOTE: Where it is indicated that a service may operate in a specific frequency band subject to not causing harmful interference, this means also that this service cannot claim protection from harmful interference caused by other services to which the band is allocated under Chapter III of the Radio Regulations.)
