The SE is traditionally the base model - lowest performance engine, lowest specification. Depends on the exact car, though. Look them up on www.drive.com.au under the 'value your car' section on the left. This will bring up the model you want and you can click each badging to see what they had. 95% of the time this is accurate.
FWIW, I had an 89 Corolla SE - it had the carby 1.4l 6A engine, and no p/s, a/c, etc. The 89 Corolla CS came with the carby 1.6l 4A engine, and from memory had the p/s and a/c available as options.
