There's a Sony $300 cash back for the Sony A7 III until 2/1/2022, to take the cost down to $1864.
The savvy shopper will price match this at the Sony store, to stack with CR's or SB 10% cash back @ Sony. Net cost ~$1667. Even less if you pay with ANZ VISA and get 11% cash back.
[Edit 30/12/21] Extra 5% off next 2 days (ends 31/12/21), code BYEBYE21.
I put my price match on the 25th and haven't heard anything from Sony :(
