NAVIGATION (COMPASS) REGULATIONS - REG 3
Interpretation
3. (1) In these Regulations, unless the contrary intention appears:

"approved person", for the purposes of a regulation in which that expression occurs, means the Authority;
"the Act" means the Navigation Act 1912.
(2) Where a term used in these Regulations is defined in section 187A of the Act for the purposes of Part IV of the Act, that term shall, unless the contrary intention appears, have the same meaning in these Regulations as in that Part of the Act.
(3) A reference in these Regulations to a form by number shall be read as a reference to the form so numbered in Schedule 1.
(4) A reference in these Regulations to Marine Orders is a reference to orders made under the Navigation (Orders) Regulations as in force from time to time.

Application
4. (1) Subject to subregulation (2), these Regulations apply to and in relation to:
(a) ships to which Part II of the Act applies; and

NAVIGATION (COMPASS) REGULATIONS - REG 7
Examination and adjustment of compasses
7. (1) The compasses of a ship undergoing its first survey to which these Regulations apply shall be examined and, where necessary, adjusted by an adjuster of compasses before the issue of a certificate of survey, a passenger certificate, a certificate of equipment, a passenger ship safety certificate or a cargo ship safety equipment certificate for the ship.
(2) Subject to subregulations (3), (4), (5) and (6), the compasses of a ship, not being a ship to which subregulation (1) applies, to which these Regulations apply shall be examined and, where necessary, adjusted by an adjuster of compasses before the ship first goes to sea from a port in Australia after:
(a) the ship has been laid up for a period of three months or more;
(b) the ship has been surveyed in accordance with the requirements of the Act and of Marine Orders, Part 21 (Equipment - Navigational), as in force from time to time, for the purpose of the issue or renewal of a certificate under Division 2 or Division 2B of Part IV of the Act, other than a cargo ship safety construction certificate, a cargo ship safety radiotelegraphy certificate or a cargo ship safety radiotelephony certificate;
(c) the ship, not being a ship registered in Australia, is licensed to engage in the coasting trade;
(d) the ship, a part of the ship or equipment on the ship has been overhauled, altered or repaired so as, in the opinion of a surveyor, to affect or be likely to affect the accuracy of the compasses of the ship; or
(e) the master of the ship has received a notice under subregulation (3).
(3) Where a surveyor has reasonable ground to believe that the compasses of a ship are or are likely to be unreliable, he shall give notice in writing accordingly to the master of the ship.
(4) Where the compasses of a ship would, but for this subregulation, be required to be examined and, where necessary, adjusted by an adjuster of compasses before the ship first goes to sea from a port in Australia after an event referred to in paragraph (a), (b) or (c) of subregulation (2) and the Authority is satisfied, after report to him by a surveyor, that further adjustment of the compasses of the ship after that event is unnecessary, he may, by writing under his hand, subject to such conditions as he thinks fit, exempt the ship from the requirements of that subregulation in relation to that event.
(5) Where:
(a) the compasses of a ship would, but for this subregulation, be required to be examined and, where necessary, adjusted by an adjuster of compasses before the ship first goes to sea from a port in Australia after an event referred to in paragraph (b) of subregulation (2); and
(b) the surveyor is satisfied from evidence produced by the master of the ship that the compasses of the ship have been properly examined and adjusted during the period of fifteen months immediately preceding the date on which the ship was so surveyed;
the ship is exempt from the requirements of subregulation (2) in relation to that event.
(6) Where the compasses of a ship, not being a ship registered in Australia, would, but for this subregulation, be required to be examined and, where necessary, adjusted by an adjuster of compasses before the ship first goes to sea from a port in Australia after the ship is licensed to engage in the coasting trade and the compasses of the ship have been adjusted for the Southern Hemisphere before the ship is so licensed, the ship is exempt from the requirements of subregulation (2) in relation to that event.

(5) Where:

(b) in any other case - a fee equal to the travelling and subsistence expenses which would have been necessarily incurred if the adjuster had travelled from the nearest port or out-port at which an adjuster is stationed to and from the ship for the purpose of performing those services.
(8) The fact that a fee is, by virtue of a particular subregulation of this regulation, payable in respect of services shall not be taken to prevent a further fee, or further fees, being payable in respect of those services by virtue of another subregulation, or other subregulations, of this regulation.
(9) Where a fee payable under this regulation in relation to the services of an adjuster of compasses is not paid, the amount of the fee is recoverable from the person who requested those services as a debt due to Australia.

(a) Magnetism
(i) Magnetic properties of materials, induction, susceptibility and
permeability. Magnetic effects of electric currents, including
calculations.
(ii) Terrestrial magnetism. Dip, total force, horizontal force and
vertical force. Effects on the deviation of the compass accompanying change
in the values of these elements. Variation.
(iii) Ship's magnetism. Hard and soft iron. Permanent, sub-permanent
and induced magnetism. Components P, Q, R; the rods a, b, c, d, e, f, g, h,
k. The approximate coefficients A, B, C, D, E, and the causes of sextantal
and octantal deviations.
(iv) Heeling error, Lambda, Lambda two and Mu.
(b) Compass Compensation
(i) General principles of compass correction. Methods of finding, and
compensating a compass for, the various components which might cause
deviation, including the effects of heel and trim.
(ii) Compensation by use of the Kelvin deflector. Principle of the
deflector method and information which can be deduced from readings
obtained.
(iii) The siting and lining up of compasses with due regard to the
proximity of magnetic material, electrical devices and other disturbing
influences.
(iv) The theory of degaussing in ships fitted with M coils and compass
compensation by means of B and heeling error coils.
(v)Swinging ship and the analysis of a deviation table. Analysis of a
deviation book of a foreign-going ship to determine causes of irregular
deviations, and suggest measures for their removal.
2. Compass Design and Electricity - one 3-hour paper
(a) Compass Design
(i) Size and relative position of compass needle.
(ii) Location of soft-iron correctors, and permanent magnets, with
reference to each other and to the compass needles with due regard to
standard binnacles of all types, overhead compasses, and pole compasses,
and the probable effects if conventional limits are not complied with.
(iii) Relative position of lubber line, card, pivot, and gimbal axes.
(iv) Types of quadrantal correctors; their advantages and
disadvantages.
(v) Detection of errors in instruments.
(b) Electricity
(i) Electrical currents and their production. Simple cells of the
primary and secondary types, including the effects of polarization.
(ii) Electromotive force, resistance and current.
(iii) Ohm's law. Kirchhoff's law. Lenz's law. Faraday's law.
