There's tons to do in the airport - free showers for connecting passengers, Korea Traditional Culture Experience, shopping, good food etc. Free nap room too.
You can also fly KE if you want, they check bags to other airlines even across alliances:

Personally, GMP and HND are much better airports for their simplicity and ease of access - but if you're worried about a layover issue, just stick to ICN. The MCT for GMP-ICN flights for international by the way is around 3 hrs for both KE and OZ. So 4 hrs is technically more than enough.
It's good to know KE will through-check bags to AC even on separate tix.
Do you think assuming 1hr to go from gate through immigration/carrousel/customs to landside is a pretty conservative estimate? And do you think allowing 1hr to purchase bus tix, wait for the bus, then the drive time to ICN is also a fairly safe estimate? Flying OZ into ICN would be the safest option, but it's also $400 more than going to GMP.
