I don't think what a few AFFs are doing in Australia will cause AA to remove YUPP fares. There are many more yank based FFer talk forums that discuss how to do this to get the lowest $ / mile routings. Here is the HNL - PTY quick run I did. Please note it is not optimised for min O/Ns nor for lowest $/SC cost:

I suspect there are better routings and lower $/SC runs available. I feel HNL is a better place to start and end the run than mid to north west coast US cities.
One way raw miles and SC earns are:
Hnl-Lax (F) = 2,556 miles for 150 SCs
Lax-Las (F) = 236 miles for 60 SCs
Las-Dfw (F) = 1,055 miles for 90 SCs
Dfw-Msp (F) = 852 miles for 90 SCs
Msp-Mia (F) = 1,501 miles = 120 Scs
Mia-Pty (J) = 1,151 miles for 60 SCs.
Total SCs are 1,140, total miles are worth 14,702 QF points. Platinum 100% bonus will boost that to 29,404 points. AA 50% cabin bonus will further boost points to 36,755.
A J* Syd-Hnl rtn in Starter + points, no check-in baggage will cost around AUD1,200 and earn 140 SCs plus 20,296 points for a WP.
Total cost would then be around AUD$2,500 and earn 1,280 SC plus 57,051 points for a WP.
