Well During Easter, there is a "Easter in the Country Festival" in Roma. The festival lasts over the 4 days of Easter.
There are plenty of bush camps along your trip. But depends from where you are departing from for the trip.
No free camps in Roma. Again Google bush camps in area and also google the festival for more info.
We hope to be in Roma over that EASTER.
Google is your best friend.

We have found that away from the major holiday spots that there is plenty of room inland everywhere at Easter. People tend to go not too far to one spot, usually coastal or riverside not too far from the main cities and sit for the 4 days, making the roads quiet except for Good Friday and Easter Monday.
