UNSOLVED Australia - Mr Cruel, serial child rapist, active 1987-1990, Melbourne, Vic.

What they need is someone like former FBI profiler Robert Ressler to come in and look at the cold case. Someone who understands these monsters and how they think.

In one of the video's I watched they said one detective thought Karmein Chan’s murder was done by a Robber who was killed in a shootout with police. Apparently one of his accomplices thought he was Mr. Cruel.

It is amazing that according to reports he used a condom, which is not common with Pedo's or rapists because they want to "Own" the person, and defile them.
He also made them bathe after which tells you that he wants nothing left for forensics, which for DNA was in it's infancy. DNA was not something that an every day criminal would know anything about in 1989.

Perhaps he had a specific STD or other identifying marker he did not want to pass on, which would have narrowed down suspects if detected?

Perhaps but to me it smells more like an in-depth knowledge of the latest advancements in forensic science. His insistence of the girls clipping their nails suggests he knew of DNA analysis and had an inkling that eventually DNA would be extracted from fingernails

More on why I think he downplayed his intelligence/pretended to not have as high an intelligence:
The house. As one person in Reddit mentioned he probably doesn’t have direct connection to the place (or places as I too suspect he used multiple) he used to hold the girls which suggests he knows the people who own it and probably had permission to use it while they are away (likely someone from work). By using this method he would be able to ensure no one would find him on deed registries. Once again I think we need to talk to forensic scientists living in the area at the time and see if they had any colleagues they would let stay at their place while they were away. Then we can cross reference if those houses were anywhere near medium to large airports and that would lead us more to him.
