This post is just to cover one particular Australian passenger service, West Australian Airways (WAA) Perth-Adelaide service which actually saw the deployment of Dh. 66 Hercules aircraft to fly the route making WAA the only civil user of the plane other than Imperial Airways (The British 'Flag Carrier' founded in 1924), as such it's the most likely one to see Tarrant Tabors had they come into existence.
The service was inaugurated in 1929, making it too late for use in Masks, though really there is probably little to stop a Keeper from moving the start date back to allow its use. Like all early commercial services it was tied to a mail contract, in this case the mail was being taken off the Trans-Australian (Port Augusta - Kalgoorlie) train in Adelaide and flown to Perth where it would be taken to the port of Fremantle by road, thus cutting a three day journey to an overnight trip.
What follows is taken from a description provided in a WAA Brochure about the flight that dates to 1930 (Linked at the end of this summary). Tickets for the flight could be purchased at the same time as the train ticket or from an agent in either Perth or Adelaide. Passengers were picked up either from Adelaide Train station or their hotel and driven to the airport in a company bus, once luggage, passengers & mail were loaded, for a planned departure (in 1930) of 10am. The first leg of the flight was Adelaide - Ceduna. At Ceduna (Approx 1:45pm) the plane would be refueled and checked for the next leg of the flight while the passengers enjoyed a buffet lunch.
Departure on the next leg Ceduna - Forrest, which took the passengers from South Australia to Western Australia occurred around 2:15, arrival at Forrest was timed for 5 pm, where again the plane would be inspected/refueled while the passengers enjoyed a three course dinner. Passengers could then sleep in the airline hostel until woken at 3:50am. Breakfast followed at 4:30 am with the departure taking place at 5 am.
The plane would reach Kalgoorlie at around 8:30, be refueled/inspected while the passengers enjoyed refreshments and then take off for Perth shortly after 9 am (The brochure mentions some passengers got off/on at Kalgoorlie). The Perth Airodrome (Then located at Maylands.) would be reached shortly after 1pm. Mail would be offloaded for distribution, passengers would be taken by company bus to their hotels.
What did this avoid, as I noted earlier, the Trans-Australian ran Port Augusta - Kalgoorlie, the reason for this was this was the extent of the standard gauge line, aside from a three day crossing of the Nullarbor Plain, travelers avoided the break of gauge at Kalgoorlie and the resulting cross platform transfer from the Trans-Australian to the Perth-Kalgoorlie Westlander.
