In reviewing the revised reward charts, how do I determine the mileage requirement from Guam (Oceania) or the Philippines (South Asia) to Australia? In both region pairings (ie, GUM-SYD; MNL-SYD), no mileage requirements exist even if the flight pairaings are possible (ie, GUM-SQ-MNL-SQ-SIN-SQ-SYD and back).

If anyone can clarify this for me, there are a number of faithful OnePass members here in GUM, the CNMI, and Micronesia who I know will want to visit Australia.
