The only time that NG released an Australian model in 400 scale this year was in April when they released the Jetstar A320neo. And spare a thought for the likes of New Zealand or Fiji, they haven't had a release from anyone really in ages.
The Australian releases this year have been from (not counting flaps-down releases)
JC Wings - 14 (mostly Qantas)
HX Models - 6 (All Qantas)
3D Design Deck - 5 (+1 November Release)
Aviation 400 - 3 (All Qantas)
Apollo - 2 (Both Qantas)
Gemini - 2 (Qantas/QantasLink)
Aero Polaris - 1 (Qantas)
NG Models - 1 (Jetstar)
Panda Models - 1 (Qantas).
NG have certainly had better years for Australia, and I feel that they could have released maybe 1 to 2 more Australians.
