Perhaps, but it’s probably better than Labor being controlled by the far left from outside the party (in the Greens), because they were hanging on to power by the skin of their teeth.
In fact, what you’ve said is an oft-repeated cliche by the media; in truth I see Malcolm as a politician who is very centrist, and has in fact dabbled with joining Labor in the past, who is balanced by conservative voices.
In contrast, I see Bill Shorten as a politician, with his deep union roots, as quite socialist, who is now being dragged further to the hysterical far left.
So, centre of the right win Malcolm versus way to the left of the centre of the left Bill. Know which sane voice I’d want as PM!
