Doesn't matter, unless you take in the actual snake that bit you, they will administer broad spectrum anti-venene. They won't take your word on species.
If you take in the snake that bit you all that will happen is the nursing staff and doctors will run the other way.... And they won't administer any antivenin unless you show signs of being envenomated
Generally antivenin is has it's own complications and side effects so they don't administer it unless they have to
A lot of snake bites are either dry or show no signs of envenomation.
The venom travels through your lymph system which is low pressure and relatively slow moving. Your Lymph nodes are very good at getting rid of stuff.
Untreated the toxins in snake venom over whelm the lymph nodes and flood into your system. Proper first aid and application of a compression bandage slows the lymph system down even more and will generally give the lymph nodes enough time to deal with the toxins. So what they'll do when you get to hospital is put you under observation and do some tests. if you show no signs of complications they take off a little bit of bandage. wait a while and repeat....
A swab of the bite area will be a far more reliable indicator of which antivenin is needed then a dodgy ID from some a non expert in a bit of a panic after being bitten by a snake
(which is why it's important not to wash the wound or try to suck the poison out like in an old cow boy movie)
Proper first aid is crucial

Snakes are cool, leave them alone and mostly they'll leave you alone and remember since the introduction of antivenin and proper first aid awareness more people die in Australia from bee and wasp stings then snake bite.
And just a reminder how hard it is for non experts like us to positively ID an Aussie snake
