1 Introduction1.1 Scope of ReportThis document is a report on the engineering investigations that have been undertaken into theinfrastructure requirements and associated estimated capital costs to upgrade Kingscote Airportfor four (4) separate future development scenarios. This airport is the only point of entry toKangaroo Island for regular passenger transport (RPT) aerial services.The work was undertaken on behalf of the Kangaroo Island Council, the owner and operator ofthe Kingscote Airport. The Study brief was jointly developed by Pacific Aviation Corporation andthe Council.1.2 Purpose of ReportThe State Government (via the Kangaroo Island Futures Authority) is undertaking a series ofwide ranging reviews to determine appropriate strategies for the future development of theIsland. The potential for increased visitation, particularly by overseas and interstate tourists, hasbeen recognised as a major component of future local economic activity.Kingscote Airport is one of only two major points of entry onto Kangaroo Island, the other beingferry services. The efficiency of air services is crucial for future development of and growth invisitation to the Island.Outputs from this Study (i.e. capital and ongoing cost estimates for the various futuredevelopment strategies) will be input to a number of cost benefit analyses and other broadranging policy development processes with a view to determine the most appropriate strategy forfuture economic development on Kangaroo Island, the most efficient aerial transport service forits community and the tourism traffic, and the appropriate level of development of KingscoteAirport.1.3 Study BriefThe project brief was outlined in Tonkin Consulting’s letters dated 31 August 2012, and amendedby further letter dated 11 September 2012 and e-mail dated 17 September 2012. However, theexact requirements of the Kangaroo Island Council have been further determined throughongoing discussion, and through receipt of advice of the requirements of third parties (e.g.Pacific Aviation Corporation, Econsearch, etc.). Accordingly, scope management has remaineda key issue throughout the course of the project investigations.1.4 Study MethodologyThe four future development scenarios considered in this Study are detailed in Section 3.1hereunder. Scenario 1 was simply to maintain the status quo at Kingscote Airport. As TonkinConsulting developed Kangaroo Island Council’s asset management plan for this airport, themethodology for this scenario was simply to draw upon the costs estimates developed in thatpast work, updating where necessary.Scenarios 2, 3 and 4 involved upgrading the airport to cater for larger aircraft. The methodologyadopted for these future development scenarios was to undertake preliminary geometric designwork and indicative pavement design for the required airside extensions, determine terminalbuilding spatial requirements at the element level, and then finally derive estimates of capitalcost.Ref No. 20120935DR1A Kingscote Airport Infrastructure Study Report 1
2 Background and Context2.1 The PresentThe vast majority of visitors to and from Kangaroo Island must do so via one of only publiclyavailable means, namely: Via Kingscote Airport, the only place on the island serviced by RPT air services. All arrivalsat this airport emanate from Adelaide Airport, and similarly all departures from Kingscoteare destined for Adelaide. Via Sealink Ferry, which operates between Cape Jervis on the South Australian mainlandapproximately 100km south of Adelaide and the port of Penneshaw approximately 60kmeast of Kingscote by road.Whilst overall visitor numbers to Kangaroo Island have enjoyed an upward trend over the lastdecade, total passenger numbers through Kingscote Airport have fallen slightly over the sameperiod. Various reasons have been put forward for this declining share of the air traffic mode.These include, but are not limited to: Lack of convenience – particularly for overseas visitors – in having to transit throughAdelaide Airport. Current marketing advantage enjoyed by Sealink, in that they can arrange, upon initialenquiry - and in addition to ferry booking - appropriate “packages” for visitors includingaccommodation on Kangaroo Island, and land transport - both on the Island and betweenAdelaide and Cape Jervis. The operator of aerial RPT services to Kingscote from Adelaidedoes not offer such broadening of its usual operational scope.At present, the RPT service to and from Kingscote is via Saab 340 aircraft – 34 seater turbo-propplane.2.2 The FutureThe South Australian Government has recognised the significance of Kangaroo Island as adestination for international and interstate visitors, and is of the belief that there is great potentialfor increased visitation. Various studies are underway into those factors that could limit futurevisitation to the Island. Kingscote Airport has been identified as a key area for future study.Essential prerequisites for the success of those strategies aimed at driving up visitation to theIsland would be appropriate facilities and efficient and convenient air services to KingscoteAirport. The latter point (efficient air services) applies particularly, although not exclusively, foroverseas visitors. Kingscote Airport in the future would need to be the destination for flightsemanating from, and origin point for flights to, other Australian cities such as Melbourne andSydney.Aviation economics will dictate that the possible future longer haul flights operating to and fromKingscote will be by larger aircraft (70 seat turbo-prop aircraft, regional jets or single aislemainline jets). To meet possible future needs, a full review of airside facilities, terminal building,third party services and landside infrastructure at Kingscote is necessary.This Report outlines those initial reviews, as undertaken for this Study. Infrastructurerequirements for four different future development scenarios have been determined, andindicative capital cost estimates associated with each have been prepared. These have beenpresented in Section 8 below.The details of the four scenarios considered are listed in Section 3.1 below.Ref No. 20120935DR1A Kingscote Airport Infrastructure Study Report 2
