10/11 SFO-SYD, $711 at OLCI. As it's a long overnight flight and I had to do stuff when I hit the ground, I took it.
10/19 SYD-SFO, $890 AUD at OLCI -- or $568 USD. Declined this time.
Both times were K fares, so yes it's definitely possible to get UFC.
Wonder why the price disparity on the return flight? Noticed loads across the board were much lighter than the outbound (nearly full). Perhaps the UFC pricing is dynamic based on load factors?
