601 think you are missing the point here ,wtf were they doing leaving the controls and a hot refuel with avgas, now there is one for the safety management system or in this case a not !
I don't think I was missing the point. I was making the point that downunder two people are required to hot refuel a helicopter.
"Hot refuelling" of a helicopter in Oz is permitted providing the procedure is written in the OM and is in accordance with CAO 20.10.

Leaving the controls of a helicopter is also approved by CAO 95.7.7. The procedure would also is covered in the OM.
https://www.legislation.gov.au/Details/F2010C00712
As these two CAO are exemptions against different CARs, you cannot combine both exemptions to hot refuel by yourself.
As I said in my OP, hot refuelling (in Oz) requires at least two people, the pilot at the controls and the refueller.
