Just found a discount code for Etihad Airways, I am not sure of it's expiry but it worked for me for travel to Munich from Melbourne.
Dep 29 Sep and Ret 16 Oct for 1052 AUD. It also works for multi stopovers too. I am not sure if it works for destinations other than Europe. Thanks

Update 2: Also available, 15% off codes - Economy: STFECO and business: STFBUS Thanks The Champagne Mile
You must travel between September 15 – December 14, 2016, on Etihad flights only (no codeshares) and book direct by June 29. Expired
