Using the 2014 CAPAD data I have created example osm files for 
Queensland for your perusal and comment. The files are available here:

The whole state is in capad2014_qld.osm.gz and I have attempted to split 
the data up into geographical clusters with the view to using this as a 
mechanism to split the import task up so that more than one user can 
work on it at a time. The method for splitting up the data needs a 
little refinement as it is making them rather uneven. You can see from 
this list of the number of nodes, ways, and relations:

capad2014_qld_batch00.osm.gz : 6904 94 19

that some batches are going to be a lot more work than others.

Some notes about the tagging:

* I made up the tags very quickly so think of them as preliminary.
* Turns out that the unique identifier is also unique to the edition of 
CAPAD ie: ref in 2012 is not the same as in 2014, hence capad2014:ref.
* The note:capad on some ways is not intended to stay in OSM but has 
been added so that users can tell why some ways have been split in their 
batch (it's required for an area in the adjacent batch).
* The nodes with a note tag have been added as JOSM complains if a 
segment is longer than 15km (also the note needs to be worded better).

Thing left to do:

* Develop a tagging plan. Needs to wait for the 2016 edition to get 
published so we can see what data will be available. Also need to think 
about which IUCN categories get a leisure=nature_reserve tag.
* Sanity check the names of the areas (eg: some states use 
abbreviations) and the operators.
* Come up with a way of task managing (only a problem if there is more 
than one mapper working on the import ;-) ).
* Figure out how to do QA (or more correctly QC).
* Write up a import wiki page.
* Run the gauntlet that is the Imports mailing list.
