OP should also be using awardnexus.com with alerts set - along with the customary advice to get an ExpertFlyer subscription and to set alerts there as well.
Perhaps OP should look for HKG award seats DFW-HKG and then from there, use JetStar to get further south on paid tickets. OP - if I were you, I'd snatch up the best routings for the TPAC and then buy the revenue seats to Australia/New Zealand. Lots of Low Cost Carriers operating in SE Asia and Australia now.
