I suppose i'm lucky in one way that i haven't booked it yet but i need to get Lhr/SYD via CMB(having come syd/las)

Without Cathay , anyone got any bright ideas how i do it on a DONE4 without paying extra segments on a staralliance plane?

If only work booked staralliance and qantas wasn't the only one with lounges to where i live
