I would if I could... but for reasons unknown, Australia's 10th largest city doesn't have an airport, and the Illawarra Region (would be 7th largest city if counted as a "city" like the Sunshine Coast is) has an airport big enough to handle 737s, but doesn't have non-charter passenger flights from any of the airlines
since 2008.
Wollongong has about 282,000 people, while the
Illawarra region has about 457,000 people, making it bigger than the capital cities of Canberra, Hobart and Darwin.
It is also close in size to the population of the Gold Coast, which is of similar distance to a capital city... and yet the Gold Coast has a very active airport, including international flights.
Cities that are SMALLER that have regular flight services by one or more of Qantas, Virgin, Jetstar, Tiger, Qantaslink...
Hobart (216,000)
Townsville (172,000)
Cairns (143,000)
Darwin (132,000)
Toowoomba (110,000)
Launceston (86,000)
Albury-Wodonga (85,000)
Mackay (82,000)
Rockhampton (78,000)
Bundaberg (70,000)
Gladstone (44,000)
Hell, even Mudgee with a population under 10,000 has a regular passenger plane service, flying 3-6 times a day between there and Sydney.
It is really weird... and would be a great vote-winner at state and federal elections to promise to build/upgrade one.
