I can’t see any usable difference between these two birds. Curious that your comment (and photos) implies that there should be a difference at the head end.
Even if these two might be different, that doesn’t mean it is a sex difference. HANZAB mentions female “Very similar to primary male, though never have obvious bright blue patch on rump” . That was the only thing that I had ever thought of as a clue. Though
the blue is over the back (hidden by wings when perched) but does not extend so far down to the rump.

Subject: [canberrabirds] Distinguishing between male & female Kookaburras
This pair of Kookaburras regularly visit a holiday house near Batemans Bay. I would appreciate any advice as to distinguishing between the male and female. Click on the thumbnails for a larger view.
Although the head structure appears slightly different, Kookaburras have the ability to flatten their head feathers, so I don't think this is a differentiator. The bird on the left has slightly darker head colouring - and the dark stripe below the eye is slightly
darker, longer and more rectangular than the stripe on its mate. Any tips on gender identification would be appreciated.
