From the new article:
I wonder why they picked ADL then? Sure, it's the largest city they could fly to (given BNE, SYD, MEL, PER are out of bounds), but the terrible flight times would totally negate this as a consideration. I guess the considerations are:
- Must be an AU destination (e.g. can't go to AKL) under the terms of the regional loophole
- Can't be BNE/SYD/MEL/PER
- Apparently CBR doesn't work
- Must have the ability to cater for international widebody flights (ruling out NTL and many other domestic-only airports)
- Must not have a curfew (ruling out OOL)
Putting on my armchair airline CEO hat on, some of the alternatives could be:
| Airport | Pros | Cons | 
| WTB (Toowoomba) | Possibly get QLD govt funding for launching a new international route No curfew
 Airport can accommodate international widebody planes
 Possible freight route
 | No border force presence currently, although talks had previously been underway (pre-COVID, and during the construction of the quarantine facility) | 
| MCY (Sunshine Coast) | Possibly get QLD govt funding for launching a new international route No curfew
 Airport can accommodate international widebody planes
 Border force already present on a seasonal basis (MCY-AKL route)
 |  | 
| TSV (Townsville) | Possibly get QLD govt funding for launching a new international route No curfew
 Airport can accommodate international widebody planes
 | 
No current border force presence (although the airport has previously hosted international flights)| Starting to get a bit far from MEL | 
 | 
| CNS (Cairns) | Possibly get QLD govt funding for launching a new international route No curfew
 Airport can accommodate international widebody planes
 Border force already present
 | Pretty far from MEL | 
| DRW (Darwin) | No curfew Airport can accommodate international widebody planes
 Border force already present
 | Pretty far from MEL | 
| HBA (Hobart) | No curfew Airport can accommodate international widebody planes
 Border force already present
 | The QF lounge | 
 
EDIT: Added sly dig at HBA's lounge 

 (I know the other cities listed aren't any better)
