Hang in there! While Australian internet is pretty bad by global standards, you should be OK once you get out of the hotel with its crappy guest WiFi. Typical Australian fixed line NBN connections are usually 25 or 50mbit. 100 is common as well. So from that perspective FAF will be OK as log as you can survive your stint in quarantine!
Latency-wise the only thing I can add is that you will want to be aware of what your ISP is doing when you sign up for a plan. Some Australian ISPs including my own use Carrier-Grade NAT (CG-NAT) which can affect peer to peer games. My ISP allows users to opt out of CG-NAT if they have a valid reason - and gaming is definitely something they list as a valid reason. That said, this may not matter much once Geosearchef's mentioned fixes are in place.
