Just means C of R holders will need to be a bit more discerning (in Victoria anyway) wrt who they hire, loan, lease their aircraft to.
Scenario is no different to the old Multanova or red light camera. Infringement notice gets sent to the registered vehicle owner. Either pay up or provide details of who was driving at the time. I would hope the introduced legislation provides similar provisions. C of R holders can probably protect themselves by having the pilot sign a simple document acknowledging their obligation for landing fees incurred during the time of their hire.
I really think a mountain is being made of a molehill here.
