The EM/ES/EP/EU Civics were a disaster for Honda Australia I think (Panda, Shrek, Pazzman or someone working at a dealership confirm this) but look at it this way, EG/EH => EK/EJ => EU/ES, the difference between these three gens is pretty scary, EG and EK agruably things of beauty with engines to match and god knows how much parts available for them. Come to the EU/ES, the looks are disappointing (The ES was the main one on the ads, which to me dampened the appeal simply cause the ES isn't nice looking generally) and the engine was a 1.7L across the board? rated at 88kW wasn't powerful enough. Look at the local competition and that was game over for Honda.
Its a mix of several things that contributed to the 7th Gens lacking performance in Australia (Even if they had the EP/EM here, I doubt much would change)
