Section 6 - Goose Island Lighthouse Heritage Management Plan 2023 - Opportunities and constraints

6 Opportunities and constraints

6.1 Implications arising from significance

The Commonwealth statement of significance (section 5.1 above) demonstrates Goose Island Lighthouse is a place of considerable heritage value due to its contribution to the development of coastal navigation of Bass Strait, and its assistance during a period of increased shipping between Melbourne, Hobart and Launceston.

The implication arising from this assessment is that key aspects of the place should be conserved to retain this significance. The key features requiring conservation include:

continued use of the lighthouse as an AtoN
architectural quality of the building
interior spaces and features, which are notable for their design and/or their original lighthouse function. These include:

intermediate floors
ground floor
spiral staircase
lantern room and base
Fresnel lens pedestal

external spaces and features, which are notable for their design, details, and/or their original lighthouse function. These include:

lantern roof
balcony
tower walls and windows
store shed

Referral and approvals of action

The EPBC Act requires approval from the Minister for the Environment, for all actions likely to have a significant impact on matters of National Environmental Significance (NES).

The Act provides that actions:

taken on Commonwealth land which are likely to have a significant impact on the environment will require the approval of the Minister.

taken outside Commonwealth land which are likely to have a significant impact on the environment on Commonwealth land, will require the approval by the Minister.

taken by the Australian Government or its agencies which are likely to have a significant impact on the environment anywhere will require approval by the Minister.

The definition of ‘environment’ in the EPBC Act and EPBC Regulations includes the cultural heritage values of places.

Heritage strategy

If an Australian Government agency owns or controls one or more places with Commonwealth heritage values, it must prepare a heritage strategy within two years from the first time they own or control a heritage place (section 341ZA).

A heritage strategy is a written document that integrates heritage conservation and management within an agency’s overall property planning and management framework. Its purpose is to help an agency manage and report on the steps it has taken to protect and conserve the Commonwealth heritage values of the properties under its ownership or control.

The heritage strategy for AMSA’s AtoN assets was completed and approved by the Commonwealth Minister for the Environment in 2018 and reviewed in 2022. The latest version of the Strategy is available online.P37F

Act or Code	Description
Environment Protection and Biodiversity Conservation Act 1999 (Cth)	The Environment Protection & Biodiversity Conservation Act 1999 (Cth) requires agencies to prepare management plans that satisfy the obligations included in Schedule 7A and 7B of the EPBC Regulations .
Environment Protection and Biodiversity Conservation Regulations 2000 (Cth)	The DCCEEW has determined these principles to guide for excellence in managing heritage properties.The objection in managing Commonwealth Heritage places to identify, protect, conserve, present and transmit, to all generations, their Commonwealth Heritage values.The management of Commonwealth Heritage places should use the best available knowledge, skills and standards for those places, and include ongoing technical and community input to decisions and actions that may have a significant impact on Commonwealth Heritage values.The management of Commonwealth Heritage places should respect all heritage values of the place and seek to integrate, where appropriate, any Commonwealth, state and territory and local government responsibilities for those places.The management of Commonwealth Heritage places should ensure that their use and provision for community involvement, especially by people who:- Have a particular interest in, or associations with, the place; and- May be affected by the management of the placeIndigenous people are the primary source of information on the value of their heritage and the active participation of Indigenous people in identification, assessment and management is integral to the effective protection of Indigenous heritage values.
AMSA Heritage Strategy 2022	As the custodian of many iconic sites, the Australian Maritime Safety Authority (AMSA) has long recognised the importance of preserving their cultural heritage.This Heritage Strategy is in response to section 341ZA of the EPBC Act (1999) which obliges AMSA to prepare and maintain a heritage strategy, along with obliging AMSA to:Assist in identification, assessment and monitoring of places of heritage value in its care;Prepare and maintain a register of its places of heritage value;Protect the heritage value of places when they are sold or leased;Provide this heritage strategy, and any subsequent major updates, to the relevant minister.The strategy derives from the AMSA Corporate Plan and achievements are reported through the AMSA Annual Report. The 2020-21 AMSA Annual report can be found online.[33]
Navigation Act 2012 (Cth)	Part 5 of the Act outlines AMSA’s power to establish, maintain and inspect marine aids to navigation (such as Goose Island Lighthouse).(1) AMSA may:(a) Establish and maintain aids to navigation; and(b) Add to, alter or remove any aid to navigation that is owned or controlled by AMSA; and(c) Vary the character of any aid to navigation that is owned or controlled by AMSA.(2) AMSA, or person authorised in writing by AMSA may, at any reasonable time of the day or night:(a) Inspect any aid to navigation or any lamp or light which, in the opinion of AMSA or the authorised person, may affect the safety or convenience of navigation, whether the aid to navigation of the lamp or light is the property of:(i) A state or territory; or(ii) An agency of a state or territory; or(iii) Any other person; and(b) Enter any property, whether public or private, for the purposes of an inspection under paragraph (a); and(c) Transport, or cause to be transported, any good through any property, whether public or private, for any purpose in connection with:(i) The maintenance of an aid to navigation that is owned or controlled by AMSA; or(ii) The establishment of any aid to navigation by AMSA.

Building Code of Australia/National Construction Code	The Code is the definitive regulatory resource for building construction, providing a nationally accepted and uniform approach to technical requirements for the building industry. It specifies matters relating to building work in order to achieve a range of health and safety objectives, including fire safety.As far as possible, Commonwealth agencies aim to achieve compliance with the Code, although this may not be entirely possible because of the nature of and constraints provided by existing circumstances, such as an existing building.
Work Health and Safety Act 2011 (Cth)	The objectives of this Act include:(1) The main object of this Act is to provide for a balanced and nationally consistent framework to secure the health and safety of workers and workplaces by:a) protecting workers and other persons against harm to their health, safety and welfare through the elimination or minimisation of risks arising from work; andb) providing for fair and effective workplace representation, consultation, co‑operation and issue resolution in relation to work health and safety; andc) encouraging unions and employer organisations to take a constructive role in promoting improvements in work health and safety practices, and assisting persons conducting businesses or undertakings and workers to achieve a healthier and safer working environment; andd) promoting the provision of advice, information, education and training in relation to work health and safety; ande) securing compliance with this Act through effective and appropriate compliance and enforcement measures; andf) ensuring appropriate scrutiny and review of actions taken by persons exercising powers and performing functions under this Act; andg) providing a framework for continuous improvement and progressively higher standards of work health and safety; andh) maintaining and strengthening the national harmonisation of laws relating to work health and safety and to facilitate a consistent national approach to work health and safety in this jurisdiction.(2) In furthering subsection (1)(a), regard must be had to the principle that workers and other persons should be given the highest level of protection against harm to their health, safety and welfare from hazards and risks arising from work as is reasonably practicable.[Quoted from Division 2 of Act]This has implications for Goose Island Lighthouse of Australia as it is related to AMSA staff, contractors and visitors.

1	Objective/rationale	An AtoN is required at the South end of Goose Island to mark the island itself on the Western side of the Furneaux Group in the Bass Strait.It is a navigation mark for vessels transiting the 1.6 mile wide channel between Goose and Badger Islands; the Franklin Sound to the East; and the Banks Strait to the South.It also warns of the smaller Chappell Islands 6 miles to the South East.
2	Required type(s) of AtoN	A fixed structure is required to act as a day mark.A distinctive light is required for use at night.
3	Priority/significance	An AtoN at this site is important for the navigation of commercial ships.
4	Required measure of performance	The service performance of the AtoN must comply with the IALA Availability Target Category 2 (99%).
5	Primary and secondary means (if any) of identification	The day mark must be conspicuous. The existing 30 m white masonry tower and lantern at an elevation of 36 m meets this requirement.The light must comply with the requirements of rhythmic characters of light as per the IALA NAVGUIDE. The light must have distinct characteristics that are easy to recognise and identify. The present flashing (2) white light every 10 seconds meets this requirement.
6	Visual range	During daytime, the AtoN structure should be visible from at least 5 nautical miles.At night, the white light must have a nominal range of at least 18 nautical miles.
7	Radar conspicuousness	As the island itself will give a good radar echo, no additional radar enhancement is required for this site.
