Then, a report '4nm E of Lismore' puts the Jab. approx 11 / 10nm from Ballina, and descending inbound?
Except the Jab called Lismore traffic. He wasn't going to either Lismore or Ballina. If he didn't say where he was descending to, no-one knew where he was going. But it didn't matter, because it looks like no one heard it anyway.
