The principle aim of the program was to acquire aerial photography to enable the production of a new topographic map of the island. A number of other tasks were also required to be carried out. This report deals with each task and the results achieved. The survey work was carried out by the following people: Frank Hoogesteger - Tasmanian Department of Environment and Land Management Roger Handsworth - Platypus Engineering Richard Lemon - Australian Surveying and land Information Group Although this report touches on the work carried out by Roger Handsworth and Frank Hoogesteger, it does not cover the specifics of their work, that being the subject of separate reports to be submitted the them. Time Frame The Macquarie Island field party departed Hobart at about 5pm on Monday 25th November 1996 aboard the Aurora Australis, voyage 3 of the ANARE re-supply season.
