Not knowing what other traffic was around Dick, I can only speculate. There may have been outbound traffic on the 335 or 353 tracks you weren't aware of. From CLARK you would have been on the 300 radial. That would place the lateral separation point around 8 DME Hobart. Much easier to do that than try and do opposite direction overs and unders. Air Traffic Controllers don't try and make things hard. They look for the best solution with the least workload. Especially in a tower like Hobart where one person is doing procedural approach, departures and aerodrome control.
