Every few years, someone mentions the Boeing 737. Sometimes it's a councillor. Sometimes it's a business group. Sometimes it's a reader who has just flown back from Brisbane on a full Jetstar service and wonders, reasonably enough, why Wollongong can't have that too. It's a fair question — and the answer is more interesting, and more consequential, than most people realise.
The Shellharbour Airport Master Plan 2023 is a serious, thorough piece of engineering work. It was prepared by L+R Airport Consulting for Shellharbour City Council and it examines, in careful detail, exactly what this airport can and cannot accommodate. Reading it honestly, two things become clear: this airport has more capability than it currently uses, and it has hard physical limits that no amount of investment will fully overcome.
We think both of those things deserve to be said plainly — and acted on.
What the airport can actually handle today
Start with what the airport already has. The main runway at 1,819 metres is longer than many people assume — it technically exceeds the lower threshold for Code 4 aircraft operations. The pavement, following the 2018 upgrade, carries a PCN 40 rating, which is sufficient for aircraft up to and including the Boeing 717-200 with no restrictions at all, and for the Airbus A220-300 operating without payload limits. The apron already has bays marked to Boeing 717 size.
In plain terms: the physical infrastructure at this airport today is already capable of accommodating aircraft significantly larger than the SAAB 340B that currently operates here. The gap between what we have and what we use is real, and it matters.
The Master Plan identifies three development scenarios. Scenario 1 is business as usual — the SAAB 340B continuing as the sole RPT aircraft. Scenario 2 introduces jet or larger turboprop services — the Dash 8-Q400, Fokker F100, Boeing 717, or Embraer E190, roughly 70 to 110 seats. Scenario 3 is the one everyone imagines: Boeing 737 or Airbus A320, 180 seats, low fares, multiple airlines.
The airport's infrastructure is already capable of handling aircraft significantly larger than the SAAB 340. The gap between what we have and what we use is real — and closing it doesn't require a 737.
Why the 737 and A320 are almost certainly never coming
We know this is not what many people want to hear. But the Master Plan is unambiguous, and we think the Illawarra deserves an honest account of it rather than a vague promise that bigger jets are somehow just around the corner.
The fundamental constraint is the runway strip — the graded and obstacle-free area on either side of the runway centreline. The current strip at Wollongong is 90 metres wide. A Code 3 instrument runway requires 280 metres under current standards. For a Boeing 737 or A320 to operate here on a regular, commercially sustainable basis, a minimum of 150 metres is needed — and even that requires a safety case and CASA approval.
Achieving 150 metres at this airport is not simply a matter of grading some extra ground. The western boundary of the runway strip runs close to private land. Moving the runway centreline east to create more room would compromise apron tail clearances, likely destroy the utility of Bays 1 and 2, require relocation of Taxiway G, and necessitate clearing trees that would then fall into other protected surfaces. The Master Plan concludes that centreline relocation is not a feasible option.
Then there is the terrain. The hills surrounding the airport permanently and irremovably intrude into the obstacle limitation surfaces that Code 3 and Code 4 operations require. The airport cannot declare itself a Code 3 or Code 4 facility — not now, and not ever, regardless of what is built on the ground. Any larger aircraft operator would need to develop bespoke instrument approach procedures, departure routes and one-engine-inoperative procedures specifically tailored to Wollongong's terrain — procedures that may carry operational restrictions that erode commercial viability.
And the runway length, while technically adequate for some Code 4 types in benign conditions, falls short for a 737 operating at full passenger load to meaningful distances. One potential operator told the Master Plan authors it would need 1,980 metres to reach the Gold Coast at capacity — 160 metres more than currently available. Starter extensions could add up to 200 metres, but these require their own safety case, jet blast mitigation infrastructure along the airport boundary, and significant engineering work.
None of this is a criticism of the airport or of Shellharbour City Council. The constraints are geographic, historical and regulatory — they are what they are. The Master Plan handles them with admirable clarity, and the recommended path forward is sensible: engage with potential operators and CASA to develop a realistic safety case for Scenario 2 aircraft before committing to expensive infrastructure.
What we are saying is that the conversation in this region needs to catch up with reality. The 737 is not coming. Planning as if it might is a distraction from the genuine, achievable opportunity in front of us. Two case studies make this plain.
Two case studies: Newcastle and Ballina
Newcastle Airport is the comparison most often cited when people ask why Wollongong can't have jet services. It is a poor comparison, and understanding why matters.
Newcastle's runway is not a council-built regional airstrip. It is a full military runway at RAAF Base Williamtown — 3,058 metres long and 45 metres wide, built to Code E standards capable of handling wide-body aircraft up to Boeing 777 size. The Commonwealth owns and maintains it. Newcastle Airport operates under a lease from Defence until 2075. When the F-35 program required a runway extension, Defence funded it as part of the military upgrade. When Newcastle needed international terminal facilities, $55 million came from the federal government.
Newcastle is approaching 1.334 million passengers annually, with Jetstar, Virgin Australia, QantasLink and others serving 13 domestic routes plus Bali and Singapore connections. It is the second busiest airport in New South Wales. But it is not a regional council airport that grew organically from a 1,800-metre community strip. It is a sovereign defence asset that civil aviation happens to share.
Ballina is the airport Wollongong should be studying. It is council-owned, built on a regional community base, and it has achieved what Wollongong aspires to. The comparison also reveals, with uncomfortable clarity, exactly why terrain is the decisive constraint.
Ballina's runway is slightly longer than Wollongong's and identically wide. Both are council-owned. Both serve regional NSW populations of comparable scale. The Ballina catchment sits at around 300,000 people — Wollongong's is nearly 500,000. On paper, Wollongong has the larger market.
The difference is terrain. Ballina sits on the flat Northern Rivers coastal plain. There are no hills intruding into the obstacle limitation surfaces. The airport was able to achieve a 150-metre runway strip width, which is the minimum required for jet operations under a safety case. When Jetstar arrived in 2005 with its A320s — and Virgin followed with 737s — the airport was physically ready to accommodate them. Twenty years later, those two airlines have carried more than five million passengers between them.
Wollongong cannot replicate Ballina's jet story because the Illawarra escarpment permanently intrudes into the airspace that jet operations require. That is a geological fact, not a policy failure and not a funding gap. No investment changes it. But Ballina also illustrates something else: QantasLink runs Q400 services alongside the jets, filling the Sydney route with a turboprop that fits the infrastructure perfectly — and that coexistence works.
The aircraft that could change everything — and is already here
The Bombardier Dash 8-Q400 is the most compelling next step for this airport. It carries 74 to 86 passengers — more than double the SAAB 340B — and it operates comfortably within the existing infrastructure constraints. The Master Plan notes that CASA has already accepted the Q400 as compatible with a 30-metre-wide runway and standard taxiway configuration, and the aircraft has operated routinely at airports like this across Australia for years. No new runway width. No strip expansion. No terrain-driven safety case of the complexity that a jet would require.
The Q400 is currently operated in Australia by QantasLink, which uses it extensively on regional routes — including services from airports with very similar infrastructure profiles to Wollongong. It is a proven, commercially viable aircraft on exactly the kinds of sectors this airport serves: one to two hours, point-to-point, connecting regional communities to capital cities.
Doubling seat capacity on the Melbourne and Brisbane routes — from 34 to 74 or more seats — would fundamentally change the commercial equation for this airport. More passengers per flight means lower unit costs, which means the potential for lower fares or better frequency, or both. It unlocks new destinations that a 34-seat aircraft simply cannot serve economically. And it signals to the market — to other airlines, to corporate travel buyers, to government — that Wollongong is serious about its aviation future.
Doubling seat capacity without laying a single metre of new runway or acquiring a square metre of new land — that is the Q400 opportunity. It is real, it is achievable, and it is available now.
We are not suggesting the Q400 is the permanent ceiling for this airport's ambition. The Master Plan rightly identifies a path — long, complex and conditional — toward jet operations if the right operator, the right safety case and the right regulatory conditions align. That path should be kept open. But it is a long-term prospect, not a near-term plan.
What we're asking for
We are calling on operators of the Dash 8-Q400 to consider Wollongong. The population catchment served by this airport is approaching 500,000 people — Australia's ninth largest. The airport is certificated, instrument-equipped, and recently upgraded. The runway is long enough, the pavement strong enough, and the apron ready. The regulatory pathway for Q400 operations is, by the standards of regional aviation, genuinely straightforward.
The Illawarra has been underserved by aviation for too long. The SAAB 340B has done, and continues to do, important work — but a 34-seat aircraft will never unlock the full potential of this region's connectivity. The next step is not a 737. It is a Q400. And the time to take that step is now.
Wollongong Airport supports development of Scenario 2 operations as defined in the Shellharbour Airport Master Plan 2023. We encourage operators of the Bombardier Dash 8-Q400 and equivalent aircraft to engage with Shellharbour City Council and consider the Illawarra as their next regional opportunity.
