Our garage faces directly west and temperatures in it in the middle of summer were generally only about 1 or 2 C degrees below external temps.
The temp in the garage impinged on the house via the single brick wall between the garage and the kitchen to the point where items in the WIP had to be thrown out because they got too hot.
Ceiling is insulated with 3.5 Batts.
First step - install ceiling fan in WIP to draw air conditioned air into WIP.
Second step - install aircell foil insulation in garage door - increased differential between outside and garage by ~2 degrees C
Third step - install shade sail to provide shade on garage door - increased differential between outside and garage by a further 2.5 degrees C
Fourth step - replace aircell foil with 40mm M grade polystyrene - no effect at all - quite surprising
Fifth step - install weather seals to gaps at top and sides of garage door opening - no discernible effect
Sixth step - still to be done - fit temperature activated exhaust fan in garage ceiling plumbed externally and fit and air vent to bottom of door between living areas and garage.
Any other ideas?

Colour of door. Sheet steel door? See Colorbond solar absorption data sheet. Surprising figures.

These colorbond type doors take a re-paint real well.

Hi... just noted your topic. I had insulated door garage installed during house build with Metricon 2 1/2 years ago for North facing garage. Works great summer/winter. I also had external wall of garage insulated R2.5 and ceiling R6...
(I don't think best doors can help in WA but something similar is an option..)
