he can't do this till he has experience with R1 elapids, he has to work his way up
you can, you need to do your venomous handling course (no exceptions on this as its the requirement), and depending on who the course is through you can get a reference check from the course runners to say that YES, you have shown competence with X species used in the course (usual stuff like RBB, Tigers, Death adders) etc. Otherwise, you can get a reference from a reputable elapid keeper.
you will notice many many people in NSW start with red bellies with not much more than keeping carpets/various lizards... R1 and R2 elapids are incredibly hard to come by... how many whip snakes have you seen for sale that have been suitable for beginners, You can find a hell of a lot more taipans than whipsnakes
R1 and R2 licensing classes are completely separate from R3-R5 in the way they work.
note point 2 and point 7; Category 1 being R3, 2-R4, 3-R5
