An excellent suggestion to include BNE and environs, but my suggestion for the AU/NZ section, coming from SIN, and provided it would be allowed by the xONEx rules is: QF SIN-PER (stopover if desired)- QF PER-ASP (stopover including AYQ/Uluru side-trip and surface to SYD [by overnight train (The Ghan) to ADL and overnight train (Indian-Pacific) to SYD]; QF SYD-BNE (stopover); QF BNE-CHC; surface to AKL via WLG; QF AKL-SYD (stopover); QF SYD-LAX etc.

Driving from ASP to PER, or vice versa) is not recommended, and ASP and Uluru (AYQ) are best visited in May to September when the ambient temperature is reasonably low. The weather is also perfect in Brisbane during those months, is somewhat cooler and damper in SYD and PER, and best avoided in ADL and MEL.

If they can't visit during those months, a re-think about visiting ASP would be advisable.
