I have exactly the same issue, Safari 13.1.1 on macOS Catalina 10.15.5, sometimes it works and sometimes the loading bar hangs half way forever.Is it just me, or does the Qantas website regularly fail to load in the Safari web browser?
It's been happening to me for months, and only in Safari - works fine in Google Chrome, etc.
Sometime back everything loaded nicely except the flight searches.it very strange that so many people are having this issue. Most of my devices are Apple and I never have problems browsing in QF site in Safari.
Not had any issues with Safari per se, but definitely PayPal and Telstra NBN.I have no issues with Safari on both QF and AFF sites across multiple devices.
I am wondering if it’s a DNS issue. I use Cloudflare DNS on all my devices as it’s super reliable, and very fast.
Suggest someone with the problem gives it a go (easiest is to change DNS in your home router to 220.127.116.11)

Bizarrely had a problem the past few days trying to book accommodation and flights on Chrome. Ended up with a hassle-free experience on MS Edge which was slightly unsettling as I'm not a fan of this browser.
That says it all really...Any time you have issues with the QF site, I’d be inclined to blame QF IT as the first port of call. They are, after all, the mob who were ringing up pilots and telling them that they would be reported to their manager, because they were using their company iPad overseas (for flight planning), and who also put out a memo telling us not to use iPads to access one of the company sites, even though they’d given us iPads for that very use.
