As an ex controller, I must make the following very cynical statement about TIBA operations.
If TIBA is supposed to be safe (with no traffic restrictions, pilots make their own decision to enter and self separate etc); then why have ATC at all?
Make all airspace TIBA (because Airservices and CASA believe and tell the flying public and politicians that it is safe) and let everyone self separate. It would surely help reduce costs!!!!!!!!!
