I am sure, yes.

You would be making planet-combined.osm out of two databases:
osm-without-australia.osm (ODbL) and fosm-australia-only.osm (CC-BY-SA).

As it happens, osm-without-australia.osm is a Derivative Database of
planet.osm, and fosm-australia-only.osm is a Derivative Work of planet.fosm.
But that's immaterial - planet.osm is probably a Derivative of some other
databases, too. It being a Derivative doesn't restrict your rights under
ODbL. Once you have the Derivative Database, you are free to use it under
the full provisions of ODbL, and that includes doing whatever you like with
an "unmodified" version of it.

cheers
Richard
