Two airlines, one sky: the policy that shaped Australian aviation — Defamer

There is a line in a 1981 Commonwealth submission to a Senate inquiry that has always stayed with me. It describes the two-airline policy as a framework designed to ensure "the orderly development of civil aviation in Australia." Orderly. That word does a lot of work. What it actually meant, in practice, was that two carriers — one private, one government-owned — divided every significant domestic route between them, flew nearly identical schedules, charged identical fares, and operated under an agreement so thoroughly supervised by Canberra that they couldn't order a new aircraft without ministerial involvement. Whether that counts as orderly depends entirely on your perspective.

For Reg Ansett, who had scratched his way into Australian aviation from a single-aircraft passenger service in regional Victoria in the late 1930s, the policy was initially a constraint and ultimately a lifeline. For the flying public, it was decades of limited choice and prices set by government fiat. For the industry, it was an architecture so deeply embedded that when it was finally dismantled in the late 1980s, neither of the two airlines it had sheltered quite knew how to operate without it.

How the two-airline policy came to be

The framework didn't arrive fully formed. It evolved through a series of post-war decisions shaped by the Chifley government's failed attempt to nationalise Australian aviation outright. The High Court blocked that nationalisation bid in 1948, but the government didn't abandon its ambitions entirely. Instead, what emerged — cemented in the Airlines Agreement of 1952 and the Civil Aviation Agreement Act — was a regulated duopoly. Australian National Airways (ANA), the dominant private carrier of the day, and the government-owned Trans-Australia Airlines (TAA) would share the major trunk routes under conditions set and monitored by the Commonwealth.

ANA didn't survive the transition particularly well. Ansett Airways — by then a genuine operation with ambitions well beyond Victoria — acquired ANA in 1957, and overnight Reg Ansett found himself holding the private-sector seat in the duopoly. Ansett-ANA, later simply Ansett Airlines of Australia, would hold that seat for more than four decades.

TAA, meanwhile, sat on the government side of the ledger, operating as a commercial airline while answering ultimately to the minister of the day. The two carriers flew the same trunk routes: Sydney–Melbourne, Sydney–Brisbane, Melbourne–Adelaide, the key links between the state capitals. Route licensing under the Department of Civil Aviation meant that entry by any third carrier was, for practical purposes, impossible. The sky was allocated. You either had a licence or you didn't.

The mechanics of a managed duopoly

The policy's real engine was a capacity-matching arrangement so precise it bordered on the absurd. Under the Airlines Equipment Act, passed in 1958 and refined through subsequent agreements, neither carrier could introduce a new aircraft type without the other having the right to match it. The logic was equalisation: if Ansett ordered Boeing 727s, TAA could order the same. If TAA moved to 767s, Ansett followed. The result was a fleet of near-identical aircraft flying near-identical schedules — a striking visual demonstration of how thoroughly the competitive instinct had been suppressed.

Fares were set by government, not the market. Ansett and TAA didn't compete on price because they weren't permitted to. Service quality and on-board amenities became the only genuine differentiators, which produced a peculiar kind of brand rivalry: each airline devoted considerable energy to convincing passengers that its meals, its flight attendants, its lounges were marginally superior to the other's, while charging exactly the same fare for the seat.

I've spent time going through the ACCC's historical predecessor filings and old Prices Justification Tribunal submissions, and the picture they paint is of a pricing process that would make a modern airline's yield manager weep. Fare applications, supporting cost data, government review, approved increases. The whole system moved at the speed of bureaucracy, not the speed of a market.

For freight and charter operators there were narrow exceptions, but on the trunk routes the duopoly held firm. Regional aviation was a separate and more complicated picture — state-based operators and independent regional carriers worked in the gaps — but the premium traffic between the capitals was the domain of two carriers only.

What the policy actually protected

Here's where I'll offer a slightly contrarian reading: for all its anticompetitive character, the two-airline policy did produce financially stable carriers. Neither Ansett nor TAA was allowed to fail. Neither could be undercut on price by a more efficient rival. Neither faced the kind of capacity dumping that would eventually contribute to Ansett's own collapse twenty years after deregulation. The stability was artificial, obviously — propped up by regulation rather than earned through efficiency — but it was real. Both carriers were adequately capitalised, maintained their fleets, and kept flying through economic downturns that, in a deregulated environment, might have bankrupted one or both of them.

Contrast that with the post-deregulation record and the argument becomes awkward for true believers in open markets. Compass Airlines entered in 1990, the first beneficiary of deregulation, and was in administration by late 1991. A second Compass arose in 1992 and lasted less than a year. Ansett itself collapsed in 2001. The "orderly development" line starts to look less like bureaucratic self-satisfaction and more like a description of what was actually delivered, even if the cost in consumer welfare was substantial.

That said, I wouldn't romanticise it. Regulated fares were high. The absence of competition meant both carriers had limited incentive to run tight operations. And the policy required increasingly baroque maintenance to hold together as aviation technology changed and international carriers began to demonstrate what competitive pricing could look like. By the mid-1980s, it had become a political embarrassment as much as a policy.

The Hawke government and the end of the regime

The decision to deregulate Australian domestic aviation came under the Hawke Labor government, announced in 1987 with a target of full open skies from October 1990. The Airlines Agreement would not be renewed. Route licensing would end. Fare controls would be removed. Any carrier that could obtain an Air Operator's Certificate and fund itself could fly a domestic Australian route.

TAA was eventually commercialised and then privatised, emerging briefly as Australian Airlines before merging with Qantas in 1992 — a consolidation that tells you something about the structural economics of the market the two-airline policy had, in its way, accurately identified. Two carriers had been enough for the Australian trunk routes in the regulated era; after a turbulent transition and several failed new entrants, the market settled back toward a dominant carrier with a challenger, rather than the free-for-all some had anticipated.

Ansett entered deregulation with serious structural disadvantages it had been allowed to paper over under the old framework. Its industrial relations arrangements, its fleet complexity, its cost base — all had grown in the climate of regulated fares, where inefficiency didn't kill you because the government set your revenue too. When fares became contestable and a sharper operator could undercut on price, those structural problems didn't disappear. They metastasised.

The full story of how deregulation exposed Ansett's vulnerabilities — and how the subsequent ownership changes under News Limited and then Air New Zealand compounded them — is covered in the rise and fall of Ansett Australia and the Air New Zealand takeover piece. But the point I'd make here is that the two-airline policy didn't create a competitive industry held back by regulation; it created two carriers whose operating models were calibrated to a regulated world. Changing the rules without changing the carriers was always going to produce turbulence.

Reg Ansett's complicated inheritance

One thing the two-airline policy's critics often understate: Reginald Ansett built a genuine business before the framework solidified. His instinct was entrepreneurial — he saw a gap in regional Victoria, flew passengers himself, and expanded systematically. The regulated duopoly didn't create that drive, but it did eventually domesticate it. By the time Reg Ansett was eased out of active control in the early 1980s, his airline had become a large, bureaucratised carrier more comfortable managing its government relationship than competing aggressively on service.

There's a certain irony in the fact that the framework designed to ensure orderly development ultimately produced carriers unprepared for disorder. When News Limited acquired Ansett and began steering it through the turbulence of the 1990s, the airline was encountering a competitive environment it had never actually been trained for. And when Air New Zealand took the wheel, it was dealing with both the post-deregulation structural hangovers and its own strategic miscalculations — a combination the administrators' reports following the 2001 collapse would document in considerable, sobering detail.

The two-airline policy is worth understanding not as a curiosity of mid-century economic management but as the context that made Ansett what it was: large, reasonably profitable for decades, structurally fragile in ways that only became visible when the protection was removed. That's the story behind the story. For the broader pattern of Australian corporate collapses where regulatory shelter masked underlying weakness, the Great Australian Collapses archive is a dispiriting but instructive read.

The sky wasn't always free. And when it became free, not everyone who'd been flying under managed conditions was ready for it.

Common questions

What was the two-airline policy in Australia?
The two-airline policy was a regulatory framework, formalised through the Airlines Agreement of 1952 and related legislation, that restricted domestic trunk-route aviation to two carriers: one private (eventually Ansett) and one government-owned (TAA). Fares, capacity and aircraft types were all subject to government oversight, preventing genuine price competition on major routes.
When did Australia's domestic aviation market deregulate?
The Hawke Labor government announced deregulation in 1987, with full open-skies conditions taking effect from October 1990. The Airlines Agreement was allowed to lapse, removing route licensing requirements and fare controls that had governed the industry since the early 1950s.
Did deregulation benefit Australian air travellers?
In the long run, fares fell and new carriers entered the market. But the immediate post-deregulation period was volatile — Compass Airlines launched and collapsed twice in quick succession, and Ansett itself failed in 2001. The transition period imposed significant costs on the industry and, ultimately, on workers and creditors when Ansett went under.
