My "Personal Survival Kit" (PSK)

Survival Kit in a Sardine Can
Its amazing how many different “personal” or “minimum”,”emergency” or “survival” kits (PSK) lists there are in existence. Every bushwalking book seems to have a different one. Try A Google search…. I found hundreds of thousands of references. Try searching YouTube and you get 68 videos showing how to put one together.

Why are there so many when they all aim to provide water, fire, food, shelter in an emergency?

Of course, many of these references are not entirely relevant to bushwalkers, who have to carry whatever is in their kit and therefore must make savings in both weight and volume. 

So why is there no universal list for bushwalkers?

Well some items do seem to appear in all lists, in one form or another, but the inclusion of others depends on the priority you give to provision of water, shelter and food or whether your focus is upon thermal regulation, hydration, and signaling.

Perusing an equipment list from the 1965 edition of ‘Equipment for Mountaineering’ published by the Melbourne University Mountaineering Club we find a whole lot of items that the modern  lightweight and minimal impact walker would never carry or which have been replaced by better alternatives.

tomahawk, machete, handkerchieves, tin opener, cigarettes, Dubbin, song book, sharpening stone, boots with nails  …..

Another list from the mid eighties

  • water 1L 
  • whistle on a string around neck  
  • pencil and paper 
  • waterproof matches or cigarette lighter  
  • woollen jumper 
  • hat 
  • first aid (personal) (FAK)
  • waterproof jacket 
  • cord 
What changes are needed after all these years?
Well I think I would add at least four items which have become readily available since then: 

 I would then add some of the following or replace items in the list above with

  • micro-compass (if your not confident to use the sun or don’t have an iPhone or a GPS with an digital compass in built or if you don’t trust the batteries)
  • magnesium flint lighter as an alternative to a cigarette lighter
  • emergency blanket 
  • water purification tablets or water purifying straw
  • signaling mirror
  • flexible wire saw (to make tent pegs and poles)
  • fire lighters or solid fuel tablets
  • candle
  • collapsible water containers eg condoms hold 1L and can be protected by a spare sock
  • needles and thread
  • safety pins
  • scalpel blade(s)
  • length of plastic tubing for siphoning or to reach inside rock cavities or “yabbie” holes
  • cable ties
Often it is possible to combine some of the items eg a whistle, compass, thermometer, magnifying lens, signalling mirror, torch (Coghlan 6 in 1)

Now you have the kit, what sort of container should you keep it in?

A lightweight waterproof bag or perhaps a light weight metal container that can also serve to heat water in? Perhaps you could combine your PSK with your personal first aid kit.

Where will you keep it? 

On your person at all times! Ever fallen down into a creek going for water or got lost going to the loo…. some people do? This kit is designed to be carried on you at all times and to supplement things that you would normally carry in your clothing or on your belt.

The PSK should supplement what is being carried in you pack ( see later blog) and this in turn will be determined by
  • weather (storms, season, heavy rain, cold, sun)
  • terrain (river crossings, snow, mud)
  • vegetation (prickly)

Why am I lost when I have a GPS?

Ever wondered how you could possibly get lost while carrying a GPS, and when you do get geographically embarrassed, whether you can trust your GPS?  


I’ve sometimes been acutely embarrassed when my high-tech equipment has been worse than useless on a difficult walk where spot-on navigation was essential. More than once,  I’ve found myself on the opposite side of a creek or on the wrong ridge-line. Sometimes I’ve returned from a walk to find that my route lay parallel to that shown on the map, but about 200m away. How could my GPS get it so wrong?


Well of course my GPS hasn’t got it wrong, it has been simply calculating position based on the incorrect settings I gave it. The indication that you’ve incorrectly set your GPS is when every feature is in the wrong place by a consistent amount.


If the error is about 200m then you have probably set your GPS to the wrong map datum eg you may have chosen Aus Geod ’84 or Aus Geod ’66 when your map shows the correct datum to be GDA94 . Your GPS must be set to the same map datum as  the map you are using.

For my Garmin Geko 201, the following datums are relevant when using Australian maps.
    Aus Geod  ’84 = AGD84
    Aus Geod ’66 = AGD66
    GDA  =GDA94
For Australian maps, the common map datums you will find are
    AGD66 (oldest)
    AGD84
    GDA94 (most recent)


Fortunately, all you have to do is to make sure that the map datum to which you set your GPS matches the one shown in the legend on your map. To do this for a Garmin Geko, select SETUP from the menu, then UNITS from the sub-menu, then MAP DATUM, and scroll down the list to select the correct one which matches your map.
