Firstly, check for crocs.

Then I recommend, while spreading a line of pyrethrym powder to keep away Hercules, that you make a quick call to snake control (keeping a clear line of sight for any circling dingoes and charging 'roos of course).

At this point you should be in a reasonable position (I would say safe, but when are you ever safe) to call in the professionals (do be sure to watch the trees for drop-bears).

 

At least that’s what I know of the SOP for such matters in Aussie.
