I'm surprised QF doesn't use the US as a main hub for flights to Europe. Pre-COVID I would be flying SYD to LHR (via LAX). Way better airports, way better connection experience than the dump that is SIN IMHO. Plus you earn more status credits and you are flying over friendly airspace at all times.
The way I see it, right now WA is very lucky. They managed to keep Omicron out, but even with these restrictions cases can still break through and took hold in the community. We saw that with Delta in Sydney with that lone taxi driver, there is no reason to believe that won't happen in WA especially with a variant which we know is at least 3 times more infectious than Delta. What will be interesting to see is how WA responds to that with closed borders. It's one thing to say we're taking away your freedom to protect you, but if you can't keep that promise there'll be a lot of upset people who will be left wondering why was it worth listening to the government all along when it came to vaccines, social distancing, etc?
