It appears that N615AR has completed it's contract work in Australia:
- Adelaide-Parafield, SA (YPPF) - RAAF Richmond, NSW (YSRI)
- RAAF Richmond, NSW (YSRI) - Cairns, QLD (YBCS/CNS)
- Cairns, QLD (YBCS/CNS)-Majuro, Marshall Islands (PKMJ/MAJ) .
N615AR had originally left it's Grand Junction CO base on 15-Feb-2012, arriving in Australia on 23-Feb-2012. Most of March had been spent working in the Adelaide area from the Parafield Airport, in what looks like aerial survey or geo-sensing operations.
