So sad - there but for the grace of God....
For those who haven't had the experience of being wedged under a coffin in the back of a 200 series Cessna: they're tricky to get through the doors but will certainly fit with the front seats in situ (always removed the rear seats in the 206). I never experienced any weight and balance issues on funeral runs in the same region. I'd be very surprised if the cargo had any bearing on the accident.
I hope the ATSB are able to provide some answers for the families, friends and colleagues.
Keep safe, S
