Q.Dying snake plant
I have had this snake plant for about 2 months. I have watered it about 2-3 times since I bought it. It lives in my room which has relatively low light. Occasionally, I put it outside on the balcony to get more sunlight. I live in Australia and it is summer time so the plant hasn’t been exposed to extreme cold.
About a week ago, I noticed that the leaves weren’t standing up straight and a closer look at the leaves showed that something was seriously wrong. The top of the soil was dry but damp towards the bottom when I took it out of the pot. I couldn’t see any clear signs of root rot when I took the plant out. I have left it for the soil and roots to dry out and trimmed the damaged leaves but I am still unsure what is wrong with the plant.
I have attached pictures of the damaged leaves and roots. Any help or advice would be most welcome!

The roots do look healthy, but overwatering could still have been the problem. It's good that you're not watering too often and that you're checking that the soil suface is dry before watering, but you should also check your soil mix. Snake plants need a very well-draining soil mix with low organic matter and no peat. They can benefit from mixing in gravel, sand, etc.

Another possibility is a fungal disease. If improving drainage doesn't help, the best option may be to cut out any damaged areas and allow the plant to hopefully regrow.
