The status bonus you only get on SK metal - so it does really not matter whether it is ticketed as TG flight or a SK (code share) in that regard. The question is if you could have gotten a better deal on the ticket if ticketed after the code share agreement was announced - check with your TA.

An interesting aspect is that if you buy economy extra on SK you will get business on the connecting TG flight. For the recerse itin of yours (CPH-SYD) I am currently trying to see if there are any good deals with code share agreement in place.
