if you're riding solo like I was and get bit, what then? Stay in bush and quickly get mobile out OR wrap and keep moving slowly for help? Or keep riding and don't let a snake spoil your ride - after all it's just 2 small holes wtf.
If you've got mobile coverage, apply a compression bandage, stay still and call for help. If you don't have a compression bandage, sacrifice your jersey or whatever. In a pinch I'd use the staps off my hydration pack (not ideal as it should be broader).
Despite having a Blue Tick (Rural use approved) Next G phone, there are plenty of holes in the coverage out here and probably where you are too, so you need to think about what you are going to do should you find yourself with no comms.
My plan is to first assess the likelyhood of someone coming along and finding me. If it's high I'll sit tight, if it's low or nonexistant I'll use as little physical effort as possible and make my way to the nearest road/point of mobile coverage.
Saying a prayer to Buddah, Zeus, God or Satan probably wouldn't hurt either.
I think there are greater dangers in the bush than snakebite, but it's worth being aware of the dangers and having a plan.
For my next decent back country trip I will be investigating the hire or purchase of an EPIRB. When I looked at them a few years ago they were the size and weight of a half brick.
My other advice is, quoting the Butthole Surfers, "It's better to regret something you have done than to regret something you haven't."
If it's all too scary, ride only in a group or buy a Play Station/X-Box/Wii.
