Hey Cam, yes Luke is right. Fuel containers are Tuff Jug.
Used to be Ballards now they're called http://www.mxstore.com.au/b/tuff-jug/

The helmet cases were from Tristan when he did Moto-D, don't think he brings them in anymore tho.
The rattle can holder thingo I think was eBay or Autobarn or something. It's just a car/seat tidy type thing.

Post up some pics when you get the trailer!!
