Looking for Tail numbers

Aviation Notable Activity
1

Hi,
I’m looking for the tail numbers of two planes:

  1. on 7th Sept 2016 the plane operated as QF1851 from CNS to AYQ (8:39-10:55 am) and later as QF1940 from AYQ to ASP (11:35am-12:09pm)
  2. on 11th Sept 2016 the plane operated as QF1871 from DRW to CNS (8:13-11:55 pm) and most likely prior to this as QF 1938 from ASP to DRW

Can anyone help to provide these two tail numbers?
In both cases the flights were operated by NJS Cobham Aviation for Qantas; the equipment was in bothe cases a B717-200.

Thank you!

Peter
