THE APPEAL
14 The introductory words of s 39A(1) focus the relevant inquiry to "a particular day"; see also s 39A(1)(e). The definition of "primary place of employment" also speaks of the primary place of employment "in relation to a day". Paragraphs (a) and (b) in the definition of "primary place of employment" require identification of whether the employee performed duties on the day in issue. If an employee did perform duties on the relevant day (paragraph (a)), then the "primary place of employment", in relation to the day, is the premises which are or were the "sole or primary place of employment of the employee" (paragraph (c)) or "otherwise the sole or primary place from which or at which the employee performs duties of his or her employment" (paragraph (d)). If the employee did not perform duties on the relevant day, it is the most recent day on which the employee did perform duties which is relevant (paragraph (b)).
15 As indicated, the primary judge did not treat paragraphs (c) and (d) in the definition of "primary place of employment" as posing different tests or requiring differing analyses. The primary judge treated paragraphs (c) and (d) as involving the same "qualitative and quantitative exercise", namely a comparison of the duties performed by employees at their different places of employment during the course of a particular day. This approach involved error, because the two paragraphs contain different tests. Paragraph (d) in the definition would be otiose if it contained the same test as paragraph (c).
16 Paragraph (d) requires focus on the place of performance of "duties". Paragraph (c) does not. That is not to say that the location from which or at which duties are performed is irrelevant in determining whether or how paragraph (c) applies; however, the test in paragraph (c) is broad and is not limited or exhausted by an inquiry into the places from which or at which the employee undertakes his or her duties.
17 The primary judge considered the ordinary meaning of the word "primary" was "first or highest in rank or importance; chief; principal". This understanding of the word "primary" should be accepted, whilst acknowledging that the statute uses the word "primary" and that word is not to be substituted by similar or explanatory words.
18 Virgin's principal business activity is the transportation of passengers on aircraft to various destinations from airports in Sydney, Melbourne, Perth and Brisbane. Virgin entered into contracts with owners of car parks adjacent to the terminals at Sydney, Perth and Brisbane to procure parking spaces for Flight and Cabin Crew. It was common ground that Virgin operated more than one aircraft between relevant airports and that Flight and Cabin Crew could be required to work on more than one aircraft, including on a particular day.
19 As the primary judge concluded:
(a) Virgin's "business premises" included the airport terminals at Sydney, Brisbane and Perth and each aircraft: [19], [87].
(b) Flight and Cabin Crew performed their duties of employment for Virgin in several places, including the airport terminal where they commenced duty and attended to matters relating to signing-on and other related pre-flight duties as outlined above. The duties were also performed on the various aircraft on which the Flight and Cabin Crew were located for the particular day, and the destination airport terminal or terminals where the aircraft land, which may not have been their origin airport or the terminal where they commenced duty: at [90].
20 Other evidence was also relevant to the analysis required by paragraph (c) in the definition of "primary place of employment". The conditions of employment of the Flight Crew were regulated by various Enterprise Agreements comprising the Short Haul Pilots' Agreement 2013, Long Haul International Pilots' Agreement 2011, Regional Airline Pilots' Enterprise Agreement 2015, Wide Body Aircraft Pilots' Agreement 2017, and the Narrow Body Aircraft Pilots' Enterprise Agreement 2018. The conditions of employment of the Cabin Crew were regulated by various Enterprise Agreements comprising the Short Haul Cabin Crew Agreement 2015 and the Long Haul International Cabin Crew Agreement 2011.
21 The Enterprise Agreements had several relevant similar features. Flight and Cabin Crew were allocated a "Home Base". Numerous rights and obligations of Virgin and the Flight and Cabin Crew were defined by reference to the Home Base including rosters, rest periods between "Tours of Duty" or "Trips", allowances, and car parking entitlements. In certain circumstances Virgin could require both Flight Crew and Cabin Crew to change their Home Base for operational reasons.
22 The period commencing when Flight and Cabin Crew "signed on" at his or her "Home Base" to "signing off" at his or her "Home Base" was generally referred to as a "Tour of Duty". Under at least one Enterprise Agreement, Virgin was required, for example, to ensure that a "Tour of Duty" or "Trip" for Flight Crew involved spending no more than 3 nights away from the Flight Crew's "Home Base" (or 4 nights with agreement of the employee), or (in certain circumstances) to provide for extended rest periods upon return to "Home Base". During a "Tour of Duty" where Flight Crew were away for one or more nights from their "Home Base", transport was arranged or reimbursed between the airport and accommodation arranged and paid for by Virgin, and meal and other allowances paid.
23 Taking into account all of the foregoing facts, in relation to each of the relevant days, the employee's "Home Base" airport was the "primary place of employment" within the meaning of paragraph (c) of the definition of that phrase in s 136(1), read with s 136(2). It was the primary place of employment on each day of the employment of the Flight and Cabin Crew, even on days where the employee did not attend the "Home Base" at all, for example, on one or more days of a "Tour of Duty" where the employee had no occasion to attend, or perform duties at, his or her "Home Base". The "Home Base" was still the central place relevant to such matters as the employee's rosters, rest periods, allowances and car parking entitlements. The "Home Base" was the central place from where a "Tour of Duty" might typically be expected to begin and end. It is relevant to the inquiry required under paragraph (c), but not determinative, that on any particular day an employee carried out central duties on aircraft away from the "Home Base".
24 The primary judge should have found, in relation to each relevant day, that the employees had a primary place of employment, being each employee's "Home Base", and that the condition in s 39A(1)(e) was therefore satisfied. It was common ground that the relevant parking facilities were provided "in the vicinity of" the relevant "Home Bases". It follows that the condition in s 39A(1)(f) was also satisfied. Given that these were the only conditions in dispute, and each was satisfied, the primary judge should have dismissed Virgin's appeals.
25 It is not strictly necessary in those circumstances to reach a concluded view about the application of paragraph (d) to the facts. The terms of paragraph (d) direct attention to the place or places from which or at which the duties were performed on each particular day in order to determine the location of the "primary place".
26 As the Commissioner submitted, it can be said that the Flight and Cabin Crew performed duties "from" the relevant "Home Base", especially on a day that the employee commenced a "Tour of Duty" from that "Home Base". It is more strained, but still possible, to say that duties are performed "from" the relevant "Home Base" even on a particular day of a "Tour of Duty" on which the employee does not set foot in the "Home Base". However, the "primary place from which or at which" the duties of the Flight and Cabin Crew are performed "on the particular day" (s 39A(1)) is the aircraft from which or at which those duties were performed. This is demonstrated by the primary judge's thorough analysis and comparison of the duties which were performed at the various different locations, which showed (unsurprisingly) that the predominant location from which or at which flight and cabin duties were performed was on the relevant aircraft. If duties are performed on more than one aircraft on a particular day, the "primary place from which or at which" the duties are performed would typically be the aircraft from which or at which the employee performed his or her duties for the longest period of time.
27 If it had been necessary to reach a conclusion on the application of paragraph (d) to the facts, the conclusion would have been that the relevant "Home Base" of each employee was not the "primary place from which or at which" the duties of the Flight and Cabin Crew were performed.
