Inthisissue This issue rounds out 2024 and our 150th sesquicentenary year of ISV. The cover shows the unveiling of the newly replaced and repositioned Henry Wade memorial plaque in Sunbury. This being just one of ISV's achievements this year, along with numerous other activities and awards some of which recognised within this issue.
We have a series of technical and historical articles kindly provided by members, including the abstract to “A proposition for the Hamlet of Portsea and Port Phillip Bay” by David Boyle. The full paper is available through the website. Also included is snapshot of the recent member survey results, and the always fascinating 50yr flashback.

Cover: This new plaque, unveiled at the Village Green memorial park in Sunbury on 10 December 2024, honours pioneering surveyor Henry Wade (1810 – 1854) who died while working in the field near Sunbury. The original plaque was installed in a more remote setting outside of Sunbury and had been stolen. It’s creation was a collaboration of the ISV, Wade family descendants and VicRoads. Following two years’ work, a new plaque was designed and a central location decided through a similar collaboration with ISV, the Wade family, Surveyor General Victoria and Hume Council and recognises our 150 logo and our work towards the replacement during our Sesquicentennial year, the final Sesquicentenary event in a year of celebrations and history.
I sincerely wish you all an enjoyable holiday break and a prosperous 2025. Riley Ulbrich

Leastsquares-DrJaneCooke FollowingRiley'sarticlelastAuguston LeastSquaresandCadastralSurveying regulations,Iwanttoexplorehow surveyorsuseLeastSquaresinthefield andoffice.I'mnotamathematician,but I'veworkedwithsurveyorsformanyyears.

Inthismethod,thesurveyorsetsupthe totalstationandmeasuresdistancesto threeknowntargetpoints.Aftereach measurement,thetotalstationʼsposition isnʼtfullyknown.Afterthefirst measurement,thestationcouldbe anywherealongacirclecenteredonthe firsttargetpoint.
Whenmeasuringthesecondtarget,the positionisnarrowedtotwopossible locationswherethetwocirclesintersect. Thesurveyorcanthendeterminethe correctlocation.
Thethirdmeasurementintroduces redundancy,withthreecircles intersecting.However,because measurementsareneverperfect,the circleswonʼtintersectexactly.
Tofindthe"best"locationofthetotal station,weuseleastsquarestominimize errorsandgetthemostaccurateestimate.
Butwhatdoesitmeanto“usethe methodknownasleastsquares”?Let's assumethatthemostlikelylocationofthe totalstationisnearthecenterofthe triangleformedbythetargetpoints.To start,wecalculatethecoordinatesofthis centralpoint.Fromthere,wecan computethedistancefromthis"guessed" positiontoeachtargetpoint(the "computed"distance).Thiscomputed distancewilldifferfromtheactual measureddistances(the "observed"distances).Bycomparingthe computedandobserveddistances,wecan calculatethedifference,orthe"residual," foreachtargetpoint.Next,wesquare eachresidualandsumthemuptoobtain thetotalsumofthesquaredresiduals.

He finishedhiscareerwiththeOfficeof Surveyor-GeneralVictoriain2021as theDeputySurveyor-General,arolehe occupiedforaperiodof17years. Duringthistime,Davidwasthe Departmentallicensedsurveyor representativeontheSurveyors RegistrationBoardofVictoria. DavidisaFellowoftheInstitutionof SurveyorsVictoria.
Theinformationinthefollowing articlewasoriginallypresented verballybymeattheInstitutionof SurveyorsVictoriaseminaron23 February2023. Theimages providedinPowerPointformatat thetimeofthepresentationare includedwithinthearticle.
Thepresentationdiscussedthree almostidenticalapplications(1996, 2012and2022)basedonSection 103(2)oftheTransferofLandAct 1958toamendtitletotwoparcels fromLP116039(1975)atPointKing BeachinPortseainaccordancewith thedoctrineofaccretionwherethe seawardboundariesofeachparcel showedPortPhillipasanabuttal. ThelandispartofCrownallotment 96E,ParishofNepean(seeFigure1 below).
Thepresentationfocussedon Surveyor-GeneralJohnTullochʼs reportonthe2012application(as requestedbytheRegistrarofTitles) butdrawsoninformationfromthe 1996applicationandcommentson the2022application.
David Boyle Ithighlightsthethreedifferent outcomesoftheseapplicationsand thedifficultiesfacedbysurveyorsin supportingsuchapplications.
Inparticular,itdiscusses“theonus ofproof”andabilitytorelyon currentdocumentsheldbythe Registrar;theavailabilityof documentsinthepublicrecord;and, therelianceonlegalopinionover thatoftheSurveyorGeneralwhen determiningthepositionofCrown boundaries.Italsotouchesonthe rolesandresponsibilitiesofthose involvedinsuchapplications.
TheCrowngrant(1872)showedPort Philliptobeanabuttaltothelandin thegrantbutitsScheduleadvised thattheseawardboundaryofthe landwasdefinedby“theMarginof theBay”.
Itappearsthe1996applicationwas ʻrejectedʼbytheRegistrarbecause theapplicant“didnotprovide sufficientevidenceontheexpression “MarginofPortPhillipBay”-an expressionnotshowninthecurrent certificateoftitleoronLP116039.
InsupportoftheRegistrarʼs decision,theSolicitorGenerallater opinedinaMemorandumthathe was“bynomeanssatisfiedthatthis description[MarginoftheBay]is equivalenttohighwatermark”orin essence,thatthesubjectland abuttedPortPhillip.
In2012,theSurveyorGeneralwas requestedbytheRegistrar(a)to provide,ʻfromasurveyingperspectiveʼ, anopiniononthemeaningofthe phrase“MarginoftheBay”with respecttoanabuttaltoPortPhillipand (b)todiscusstheopinionprovidedby theSolicitorGeneralinhis Memorandumof1996. TheSurveyor Generalwasnotaskedtoprovide adviceonthedoctrineofaccretionor howthatmayapplytothelandinthe applications. However,assection42of theSurveyingAct2004chargesthe Surveyor-Generalwiththe responsibilityofdeterminingthe positionofCrownboundaries,a discussionofthismatterwasincluded inhisreport. Thepolicycoveringthe doctrineofaccretionstemsfromLord WilberforceinSouthernCentreof TheosophyIncvStateofSouth Australia[1982]AC706,716.
Fromasurveyingperspective, determiningthesignificanceofthe term“MarginoftheBay”wasa relativelystraightforwardtask. Itrests onthecomparisonofdimensionsof abuttingCrownallotments96Eand 100AontheParishPutawayPlan, NepeanN57(5)(seeFigure1above)and thediagramsandSchedulesofthe grantsthatresultedfromCrown subdivisionrecordedintheParishPlan. Theinformationwasconfirmedby notesandlettersfromSurveyor GeneralMr.JMReedandfrom ParliamentarySecondreading speecheswhenaneasementalongthe seawardboundaryofthelandin questionwascreatedin1910.
DiscussingtheSolicitorGeneralʼs Memorandumwasnotasstraight forwardasneithertheMemorandum noranyotherdocumentationfromthe 1996applicationwasavailablefrom thepublicrecord.
ArescindedcopyoftheMemorandum washowever,ultimatelyʻobtainedʼ fromthepersonalfilesofa Departmentalofficer. Interestingly,the SolicitorGeneraladvisedhis Memorandumwasfinalisedwhile“still waitingforadviceonsurveying matters”fromtheRegistrar.
Thislackofcriticalinformation,together withwhatseemstoreflectalimited understandingofthenatureofthe application;thesignificanceof occupationandanunpractisedor inexperiencedinterpretationofsurvey documentationsuggeststhatthe SolicitorGeneralmaynothaveheld sufficientinformationtoenablehimto advisethattherewas“insufficient evidencetosaythattheʻmarginofthe Bayʼwasequivalenttothehigh-water mark”.
TheSolicitorGeneraldidquestionwhere the“onusofproof”layindetermining thisrelationship.
Exceptfordefiningtheoriginofsome easements,theRegistrardoesnotrequire surveyorstoreturntotheoriginalCrown grantstoidentifymatterssuchas abuttalsbutpermitstheirrelianceupon thelatestregistereddocuments. Sowhy takethatapproachinthiscase? Isthere anonusontheRegistrartoaccept responsibilityforthedocumentshe/she hasregisteredandallowsurveyorstorely uponthat?
Havingascertainedthattheparcelsin questionhadanabuttaltoPortPhillip, andalthoughnotconstitutingthemajor bodyofworkfortheSurveyorGeneralin 2012,themajorissueforJohnTulloch wasthesignificantandrapidlychanging positionofthehigh-waterlevelonPoint KingBeach.
Thatis,anunequivocalacceptancethat theconditionsexistedtosatisfythe applicationofthedoctrineofaccretion suchthattheboundariesoftheparcel couldbeamendedtoaccordwiththe high-waterlevelonPointKingBeachat thedateofthesurvey. Mr.Tullochwas notconvincedthattheseconditions existedeventhoughtheDepartmentof ConservationandEnergyDoctrineof AccretionGuidelines,June1993(based onlegalʻopinionʼ)allowedforwater movementofupto7.4metresperyear, andrecommendedthattheRegistrarnot granttheapplicationbutreferittothe Court. Theapplicationwasgrantedby theRegistrarwithoutreferral. Correspondenceandcommunications aftertheprovisionoftheSurveyorGeneralʼsreportisnotavailablefromthe publicrecordbutperhapsmorecredence wasgiventolegalʻopinionʼ.
TheCourtwouldhaveprovideda definitiveoutcomesuchthatitwas notnecessarytorelyonʻopinionʼ.
Interestingly,theSurveyor-Generalʼs reportfrom2012wasnotavailable onthepublicrecordatthetimeof lodgementofthe2022application.
Infactitonlycametolightatthe timeofmakingthispresentationto theInstitutionofSurveyorsVictoria. In2022andafterthehighwatermark hadmoveagreatdealfurther seaward,theRegistraradvisedthat sheconsidereditappropriateforthe Courtstoassesstheboundariesof theparcelsinquestioninaccordance withthecommonlawdoctrineof accretionandthattheapplicationbe withdrawn.
Theeventsinthe1996and2012 applicationsseemunusual. Given thatnoinformationotherthanthe surveyorʼsplans,abstractand reportswasavailableonthepublic record,itisimpossibletoknowwhy theseapplicationswererespectively rejectedoraccepted. Whatwedo knowhoweveristhatwehavethree similarapplicationswiththree differentoutcomes. Giventhe decisionin2012nottoacceptthe Surveyor-Generalʼsadvicetorefer themattertotheCourts,coulditbe publicinterest,politics(atanylevel), orthehesitancyofthelegal professiontobescrutinisedthat playedarole?TheRegistrarʼs decisionin2022issurelythe appropriateresponsetosatisfyany oftheseʻunfoundedʼsuggestions.
Insummary,theacceptanceofthe “MarginoftheBay”ascoinciding withthehighwatermarkatPoint KingBeachleavesarealquestionat PointKingBeachof“Toaccreteor nottoaccrete”ratherthan“tobeor nottobe”asinShakespeareʼs Hamlet.
