This is excellent progress.
A big bugbear of mine for ages has been that it has always been possible to book a ticket online via Qantas from Australia to BOG and return (with either LATAM or Avianca as the Chile-Colombia connection, even though not a codeshare), but never the other way round - this should fix that.
I think expecting MDE (Medellin) is a bit much yet
LATAM do not fly direct SCL-MDE, and despite the all-emcompassing LATAM brand, they are very much still (on an operational level) still a collection of rebranded separate airlines/companies in each country.
There is also an issue with the QF/Latam alliance in that QF metal between aus and Chile has premium economy, which is not available on Latam metal, and booking thru Latam on QF metal does not allow PE bookings. (IE QF only sells business and economy through Latam) Another bug is that Latam's website does not happily allow mixed-class bookings. So although they do have PE on certain intra-south america international flights (just narrow body aircraft with the middle seat blocked and slightly greater pitch), they do not offer PE on their wide-bodies, so again booking is a pain. I suspect these things will affect the QF codeshares - I am guessing that it will be a choice of economy and business only. In any case LA572/575/576/577 are 787's or 767's that have economy and business, so maybe this will not be an issue. Also, with the 787 engine maintenance backlog, many of the SCL-BOG flights have been operated on Wamos charters - mediocre hard product
, fantastic spanish staff
, no Pisco Sours
Pro-tip 1: Unless things dramatically change, it is heaps cheaper to get a ticket between BOG and BNE/SYD/MEL etc with an add-on domestic flight to MDE, than to try to book it all as a single ticket.
As per rooflyer's suggestion, this is in some ways a tad late for me, but I still go there. Or at least I intend to when things are calmer there for me in my world
In case anyone is new to Latam, be aware also that their business model is that their international flights and services attempt to be that of a world-class airline (which they are really), but domestically in any south american country their model is pretty much that of a low cost carrier. There is no such thing as domestic lounges, etc, and they only have economy class. Baggage allowance that you have for the international travel may not be respected for the domestic parts. The LATAM lounge in Bogota is quite nice (as always excellent wines) but food is snack stuff + a few extras.
Pro-tip 2: if you are in Bogota airport waiting for one of those LATAM flights to Chile, there is a line of chairs in the lounge (second floor) that directly looks over the usual departure gate. They usually announce boarding way before it actually happens, so you can merrily keep downing that glorious wine whilst watching the queues form and linger..... You can time it to drink your last wine, casually walk down the stairs, and board just before the flight is closed. To me the 5 hour overnight flight down to Santiago is one of those horrid medium-haul flights where there is not enough time to both eat/drink/watch movie, and also sleep. So by using this technique you can board tanked, and then happily have a pisco sour prior to take-off, and then maximize sleep. God I have fine-tuned that....
