Looks identical to that. Level 1 HU same as aussie SS. My guess is that the LHD fan unit must be generic for GM, so holden just used the LHD units as is, but maybe "cheapened up" or chose not to use the LHD HVAC control module for some reason in the RHD models - maybe local manufacture vs having to buy in from overseas?
I'll snap a few pics of the control module for future reference. Getting to the std control module is gonna be fun as its right up under the dash, have just plugged in the g8 hvac control module and have it hanging down for testing. its working but throwing codes due to no sunload, ambient or internal temp sensors being fitted, but it is working without these at the moment.
Will get some pics up shortly.
