The deals on AONEx's out of KRT were removed some time ago. Those fares are now comparable to AONEx's out of first world nations.
When I still got LONE4's out of Australia, they were 3900-4400AUD depending on taxes. Though my last LONE4 was in 2009 (have since been booking DAS13's to TYO or ICN, then starting DONE3s from Japan or South Korea).
