Additional thoughts:
- Depending on when the child was dead, if it was 2007 then I would feel that the responsible person has an emotional attachment with the child for keeping it so long, as someone also mentioned in this site. I can feel it too. Without this emotional attachment, the bones and clothes would be likely to be thrown separately. It should be very easy to get rid of the clothes eg donate to Salvation Army or in the bin.
- I am feeling that the responsible person is in a new situation*, it could be a new wife, new husband, there were other children and as they grew up they could find out the bones, a new comer in his or her living space or he or she is selling home as someone has also mentioned in this site. I feel that he or she is constrained for space and time to clear the bones and clothes, he or she has to get rid of it as quickly as possible but he or she has this emotional attachment with the bones and clothes so putting them together in a suitcase. I think it was hidden in the bush not wanting anyone to find out and perhaps with the intention of collecting it back one day.

Last night or on 26 Aug 2015, on 7:30 report and the news have revealed that there was a pedophile ring that the police had cracked down. The leader of the website which runs globally, was an Adelaide man, 32yo working in the public sector caring for children! The man was caught early this year. Police globally has also caught a few others linked to the site and there could be more to come. This could be a possible reason for the responsible person to dispose the childs bones sometimes in the early to middle of this year. The man could be within the ring, afraid soon would be identified and he did killed a child.
Some years ago, there was a little boy in Victoria got hit by a car driven by a family relative outside the home while his parents were inside the home, this relative quickly put the child into the car boot and drove for a long time. He came to a remote highway and dumped the child on the side of the road near the bush. It was said that the relative was in panic, he was not an Australian resident and was looking to apply. I think it did mentioned that he was afraid to have to leave Aust.
It seems when a person is in panic, wanting to hide a body, this might be how it is done, dumped it in a remote area like the bush.
- Unless the locals are teaming up to make up a story of the suitcase man, if there is really this man, I think it is more likely than not that the suitcase man is related to this mystery. He probably doesnt had a car (perhaps a foreign traveler), or he is too old to drive, if these are the cases, he is likely to be someone living not so far from the area managed to get there.
But he could be driving, parked the car elsewhere then walk the highway. Someone in this site pointed out that he might want to avoid his car number plate captured, this might be true, good point, I think it is harder to catch a person by his face than by the car number. Also, someone pointed out that he might not want anyone to notice where exactly he placed the suitcase by having a car parked right in front of the exact location.
- The responsible person is very likely to have plenty of space of his or her own to allow a body to decompose without anyone noticed. The Wynarka area definitely can be a place to allow this to happen with plenty of space and very few people.
This might sounds revolting. The child might be wearing the tutu dress while the body was decomposing which caused the tutu dress so decomposed. I suspect that the tummy area of the dress was so deteriorated due to the bacteria from the stomach and other organs during decomposition eaten away or eroded that area of the material/texture of the dress.
As with the quilt, I am still yet trying to think it through why it is so decomposed in this way and the pumpkin patch that strangely looks brand new?
All just speculation.
