Not entirely sure why, however, presumably to conduct a survey or aerial mapping assignment of some sort, Interair Pty Ltd Piper PA-31-310 Navajo VH-FHJ flew a pattern above Shoalwater Bay Training Area (SWBTA) and surrounding region north of Rockhampton on three occasions over a four day period after the completion of Exercise Wallaby 2016.
VH-FHJ departed back to Archerfield after it's survey flight on Monday.
Meanwhile, also recently photographed on the GA tarmac at Rockhampton was Vulcanair S.P.A. P.68C VH-CFT, one of two locally based P.68C aircraft operated by Atlass Aviation, an Aerometrix owned company.
