osm-without-australia.osm and fosm-australia-only.osm are not
derivatives of each other (*), but planet-combined.osm is a derivative
of both osm-without-australia.osm and fosm-australia-only.osm.

planet-110706.osm. But pretending that OSMF starts OSM over from
scratch to come up with osm-without-australia.osm.
