This kind of thing was part of the reason we got ducted heat pumps. I'm not sure ducted is a good idea in general, individual room gives a lot more control, but cooling the room is probably the only real solution. Putting an awning outside should reduce the heat, but even then you'll probably need cooling.

 

We got some sunshade blinds from Roman Blinds Direct a few years ago, we found them excellent. Not sure if they helped with temp much, but they're much nicer than other curtains. You can choose 1% to 10% light passing through. They can do motorised blinds, but you probably don't need that for sunshade.

 

Did they also do the installation?
