I would also like to thank my friends and colleagues Caleb Campbell, Tony Miller, Jason Van't Hof, Nathaniel Watson, and Jay Iannacito. All of whom, to include Michelle, have by way of my longwinded expositions, acquired involuntary knowledge of the campaigns of the South West Pacific. Thanks for your patience and invaluable insights. A special thanks to my advisors Professor Craig Stockings, Emeritus Professor Peter Dennis, and Associate Professor Eleanor Hancock. No single individual embarks on a research journey of this magnitude without a significant amount of mentorship and guidance. This effort has been no different. ii Acronyms AAMC Australian Army Medical Corps AAOC Australian Army Ordnance Corps AASC Australian Army Service Corps AACS Australian Army Cooperation Squadron ACP Air Controller Party AIF Australian Imperial Force ALC Australian Landing Craft ALO Air Liaison Officer ALP Air Liaison Party ANGAU Australian New Guinea Administrative Unit AWM Australian War Memorial BM Brigade Major CMF Civil Military Force D Day FLEX Fleet Training Exercise FLP Fleet Training Publication FM Field Manual H Hour HMAS Her Majesty Australian Ship HQ Headquarters LAD Light Aid Detachment LCI Landing Craft Infantry iii LCVP Landing Craft Vehicle Personnel LHQ (Australian) Land Force Headquarters LSI Landing Ship Infantry LST Landing Ship Tank LVT Landing Vehicle Tracked NCO Non-Commission Officer PE Peace Establishment PIB Papuan Infantry Battalion RAAF Royal Australian Air Force RAN Royal Australian Navy SC Staff Captain SFCP Shore Fire Control Party SNFL Special Naval Landing Forced SWPA South West Pacific Area TEWT Training Exercise Without Troops WE War Establishment WWI World War One WWII World War Two iv Table of Contents Page Acronyms................................................................................................................................ iii Introduction ........................................................................................................................... 1 Chapter 1.
