This is my first post so go easy on me.
After price matching at Betta home living against Appliance Central (Betta's sister company) I picked up a Fujitsu 7.1 kW (ASTG24KMCA) Reverse Cycle Split System AC for $1600 with a $300 cash back. So $1300 in total inc gst.
Cash back is from
https://www.airconbonus.com.au
Offer is available australia wide from 1st October until 31th October.
There are multiple options available for an aircon that will suit your needs.
See available models and stores.

Don't forget to price match. ;)
Edit.
Found Stan cash is even cheaper again. $1,577.00 + cash back bonus ($1277)
