Duke, I can't see people taking it seriously when using pythons as demonstration tools. In victoria for a while the only course you could do and actually handle elapids was Hosers and his venomoids. I think it's great that now people can actually handle hot elapids. I was so dissapointed that all I got to handle was voids or childrens pythons.
There is no way to handle elapids and guarantee safety. Around more experienced keepers that can read snakes better makes it more safe but doesn't guarantee anything because accidents happen.
Tiger snakes, in my experience, are usually a very forgiving snake for newbis, I have heard of many people being headbutted by tiger snakes or they will just bluff hooding their necks and hissing. Also Tiger Snake Antivenom is very easy to get around most parts of Australia so Death from a Tiger Snake bite, you'd have to be pretty unlucky. Especially if you are in a room filled with other herpers and experienced people in Elapids and first Aid.
I don't think people would take courses as seriously or be more inclind to teach themselves with wild Elapids if all you could handle was pythons or colourbrids. Plus it'd be a stupid idea that people can get their license to catch and relocate after only practicing on pythons, that in no way would prepare you and you'd have no confidence at all.
At the end of the day, of all the courses out there being done and all the students handling elapids in these environments this is the first student bite I have heard of so I still concider courses to be pretty safe, and I am sure everyone knows before the pay that they will be asked to handle Elapids and then at the course if they are confident enough they'll be able to handle them. I highly doubt at no time anyone was forced to do these courses or forced to handle elapids if they were comfortable. So if you cope a bite it's more your fault then anyone elses because you put yourself in that situation knowing the risks involved.
