Qantas does not fly to SCL so there is your first issue. If you are using LATAM they left Oneworld on 1st May last yearThe rules are 318,000 for a J OWA,as I understand it , and have used in the past.
The route as planned is MEL - SYD - SCL with QF
BUE - ZUR with IB
Some internal Europe , as yet not planned and then
FRA - MEL with whoever
