Below: Some of the Mk 7s have been re-painted in the new green-yellow colour scheme introduced in around 2008. Here Tender 15, belonging to the ARFF Training School, is about to depart from the aircraft viewing area on Operations Road at Melbourne/Tullamarine in November 2013. With the School's fire training ground just up the road, this is a common place for the School's tenders to await the beginning of training exercises.
