My current best routing looks like:
Australia - LAX - DFW - BOS - LAX - SCL - LAX - DFW - BOS - DFW - London

i assume your constraint is:
Oz-BOS-LAX-SCL-n_america_LHR?
i also assume you could transit at more than one point in N.A. before going down to S.A. (i don't know the answer to this, some agent/airline might insist you cannot have split the 6 N.A. segments between the SCL trip)
then it could be
Oz-JFK-DFW-BOS-LAX-DFW-SCL-MIA-ORD-LAX-LHR for max miles,
or if in summer,
Oz-JFK-DFW-ANC-DFW-BOS-LAX-SCL-DFW-LAX-LHR
or some variations
