I found this little news tidbit in a Brisbane, Australia, paper, dated April 7:
A NEW DIRECTION
Heath Ledger made his directorial debut at the Ben Harper concert at the Enmore Theatre on Wednesday night. Harper told the crowd Ledger had shot the footage he uses as the backdrop of his concert. Meanwhile, over at Ledger's old Bronte digs, yet more building work is going on, just months after Ledger spent millions renovating the multi-levelled home, installing paparazzi-proof window tinting but sadly never enjoying his time there because he was too hassled by the paps.
LN note: I thought he sold the beach house in Bronte back in the early part of 2006?
