A way to do this would be to map any fence lines marking the boundaries.

Have you checked it for accuracy? The DCDBLite data for Qld had ok
accuracy in some areas, but in others it has lots and lots of mistakes
and out of date information and incorrect positioning.

We ended up using the DCDB data here to map other features like
railway lines and waterways, rather than the property boundaries

Depending on the quality of the data it may be a very bad thing to do,
this is typically referred to as implopping and with everything else
everyone wants to map the bad data is never touched or updated and
left to rot.

If this is mainly for your own use, you may be better converting it to
KML or your own pgsql DB and making a transparent layer, rather than
putting it directly into the OSM DB.
