I haven't travelled up Flaggy Creek Road, but Bunya Road has two padlocked gates - one at the Scout Camp entrance and one at the end of the road. If NBC had a key to these locks, then he and GBC could easily drive the 4WD/s closer to Kholo Creek.
However, I find it hard to imagine that they would have unlocked the first gate and entered the dirt drive to the Hall, as there are three houses that are very close to the roadside. One of these houses is directly across from this padlocked gate. It would be so quiet out there at night, any noise or disturbance would be easily heard. The end of the road would have been a better option, as there are no houses there - just the padlocked gate. And as I said, NBC may well have a key.
I agree with you Marly, Kholo Creek would be very snaggy with many broken or over hanging branches as well, and it would be a long distance for a body to travel to the crossing. However, it is much wider than Ugly Creek. Maybe this would help a body to flow through more easily than the narrow Ugly Creek?
When I visited with some other lovely posters from here a few weeks ago, I noticed a very large tree that had fallen across Kholo Creek about 20 mts up stream from where Allison's body was. This may actually be close to where Ugly Creek joins? Anyway, even though this would have been a major obstacle, I still felt that at high tide and with all the deluge of rain that we had on the Friday night before she was found, she still would have floated over or around this easily. So I believe that this could be said for Ugly Creek too. I know it's windy, but when you're there, you actually do get a sense that Allison could very well have washed down one of these creeks quite easily - despite the branches and snags in either creek.
I'm leaning more towards Ugly Creek too Marly - mostly because it's so secluded. I had an eery feeling driving up there and Mani's photos of the creek and especially the box culvert seem quite a likely place for GBC to have placed Allison's body. There are no houses close by to see a parked car or someone in action. The reports of howling dogs also speak volumes to me. Having said that, yes it's a narrow, windy creek with probably many snags as Doc said.
However, I'm probably more for GBC placing Allison upstream, because I personally feel that GBC did not place her under the crossing. Standing under that crossing, you can easily see the Brisbane River only a short distance down from where she lay. If GBC put her here, she surely would have been easily washed out to the BR with the downpour that we had. IMO the horizontal pipes would not have stopped her. She was also found so low on that muddy bank, it would have been a long way down for GBC to have carried her and also a real challenge through rough scrub, low trees and even lower branches on a fairly steep bank and in complete darkness. In addition, you would have to be an absolute i---- to park on the side of Mt Crosby Road, pull a body out of the back of the car, and carry it down the bank or even throw it over the crossing. A passerby could come at any time and there's no warning (especially people travelling inbound). As a previous poster said, any motorist would have their high beam on and would light up a parked car/s or action, just like that. But, as I said only an i---- would do this, so I maybe very wrong!
All MOO!
PS. Sorry, this has taken me ages to post, as I've had a phone call and putting two children to bed in between 'submitting'! I am very used to our lovely, fun Friday nights - hope I'm not spoiling the mood by being too serious
