Dear Minister,

RE: Australian ratification of the Minamata Convention on Mercury

May I thank and congratulate you and the Government for now progressing Australia towards ratification of the Minamata Convention.

I note the report of the Joint Standing Committee on Treaties (Report #197) has recommended ratification and to discard any potential pursuit of an exemption for High Pressure Mercury Vapour (HPMV) lamps:

The Committee supports the Convention and recommends that binding treaty action be taken. The Committee recommends the Government reassess the need to seek an exemption to allow for the continued importation of HPMV lamps into Australia, considering such an exemption to be reputationally damaging and of limited practical benefit.[1]

Further, as per the transcript of the relevant Committee hearing, the only other countries seeking this type of exemption are Botswana, China, Ghana, India, Iran, Lesotho, Madagascar and Thailand.

The following exchange at the Committee hearing underlines the point:

CHAIR: Would it be correct to say that Australia is the only developed or OECD country that’s seeking an exemption to allow us to continue to import HPMV lighting?

Ms Douglass: To my knowledge, yes.

CHAIR: It seems like rather odd company to be keeping, with those countries you mentioned.

May I please inquire, what is the expected or approximate timeframe now for Australia’s formal ratification of the Minamata Convention?

Further, could you please confirm whether Australia will – uniquely for an OECD country – seek an exemption to the Convention, or whether it will now seek to ratify without exemption?

Yours sincerely,

Michael Cornish

City of West Torrens – Net zero emissions target

Dear Mayor Coxon,

RE: City of West Torrens – Net zero emissions target

Thank you in advance for your time in considering my correspondence.

I write to you as a resident of the City of West Torrens who, like so many other residents, have deep concerns regarding how slowly Australia is responding to the threats posed by climate change and the lasting costs that this delay – let alone the delay of other countries – will have upon our local community, Australia, and the world.

I recognise that the Council’s role in this global issue is small, but its decision to act can still be important. Indeed, the Council is to be commended for all its work to date on mitigating and adapting to climate change.

However, I could not locate any evidence of a Council commitment to a net zero emissions target. It is widely understood that there will need to be a global net zero emissions target by at least 2050 – and ideally much sooner – if we are to stave off the very worst impacts from climate change.

May I kindly inquire, has the Council adopted a net zero emissions target, and if so, by what year has that target been set, and what plans have been adopted to reach that target?

If no target has been set, why not, and will you be pursuing the adoption of a net zero emissions target for the City of West Torrens as soon as possible?

Thank you again for your consideration of my correspondence.

Kind regards,


Mr Michael Cornish

Update 6: Australian ratification of the Minamata Convention on Mercury

The transcript of the hearing of the Joint Committee Inquiry into the Convention’s ratification became available within the last few days, see: https://www.aph.gov.au/Parliamentary_Business/Committees/Joint/Treaties/MinamataConvention/Public_Hearings.

Dear Mr Sharma

Re: Inquiry into the Minamata Convention on Mercury, vapour lamps exemption

I write to you as a submitter to the Inquiry into the Minamata Convention on Mercury. For additional context, I was a former Senior Adviser to the Federal Member for Mayo, Ms Rebekha Sharkie MP, with carriage at the adviser level for Centre Alliance’s environment portfolio (amongst other portfolios).

I read the transcript of the inquiry hearing of 9 August 2021 with great interest. I wholeheartedly agree with your analysis and concern for the exemption to the Convention being sought by Australia until December 2023, namely, an exemption to import restrictions for high-pressure mercury vapour lamps for general lighting purposes.

This concern would no doubt be shared by the environmental NGOs who made submissions to the Committee.

I too see no good need to delay the inevitable transition away from mercury vapour lights that is, according to the account provided in the hearing, already complete or underway in all Australian State and Territory jurisdictions.

Additionally, as you and fellow Committee Members collectively noted in the hearing:

  • The exemption would deny Australia “a benefit of $17.3 million from energy savings and around $4.4 million from carbon savings”, i.e. an estimated opportunity cost to Australia of $21.7 million;
  • Australia would be the only OECD country to seek an exemption to the treaty, alongside small group of countries – China, India, Thailand, and a cluster of sub-Saharan African countries;
  • Australia is already an international laggard in its ratification of the treaty, with (“approximately”) 120 of 128 original signatories having already ratified;
  • Seeking an unnecessary exemption may undermine Australia’s negotiating position in the future direction of the Convention, a key interest that was identified in most industry submissions to the Inquiry; and
  • The Lighting Council of Australia did not evidence sufficient concern on the matter to make a submission to the Inquiry.

Further, the serious underlying health and environmental concerns that drive the impetus of the Convention – and Australia’s ratification of it – can only be undermined by any exemption.

In conclusion, I strongly urge that the Committee recommend that there be no exemption for mercury vapour lighting sought in Australia’s ratification of the Minamata Convention on Mercury.

Thank you again for your time in considering my correspondence.

Yours sincerely,

Michael Cornish

Update 1: GIS data for SA nature park outlines

24 August 2021

Good Afternoon Michael,

Thanks for your query to NatureMaps Support and our apologies for the length of time it has taken to get back to you.

In case you weren’t aware, the Department for Environment and Water makes some of its key spatial data layers openly accessible through the Data SA web site – Data.SA.  You can find a version of the NPWSA Reserves layer (ie South Australian reserves dedicated under the National Parks and Wildlife Act, Wilderness Protection Act and reserves for conservation purposes under the Crown Land Management Act) in the following location – Conservation Reserve Boundaries – Dataset – data.sa.gov.au.  This version of the data is equivalent to the NPWSA Reserves layer in NatureMaps – see screenshot below














The procedure for supplying data to Google has changed over the years.  Previously, Google acquired a series of Australia-wide foundation data sets (including parks and reserves) from a National mapping distributor.  These National mapping data sets were updated on a regular basis from authoritative data supplied from State and Territory mapping agencies.  Under this approach, there was a clear pathway to provide updated mapping data to national and broader mapping initiatives.

Google has since stopped acquiring Australia-wide data from this National mapping distributor and now seems to favour a different approach for updating data.

Looking at information online, Google now promotes a Google Maps Content Providers program – Google Maps Content Partners – Content Providers – Google Maps.  Map Content Partners can provide their own data to improve information displayed on Google Maps – it looks like Parks and Protected Areas are part of the data that Google will accept.

In order to submit mapping data under this partner program, Google has published some guidelines defining the required format and structure of the mapping data to be provided – Geo Data Upload Content Requirements – Map Content Partners Help (google.com).  For mapping data representing Parks and Protected Areas, partner data will need to adhere to the following guidelines.

Based on these guidelines, the South Australian NPWSA Reserves layer displayed in NatureMaps will require some “translation” to a data structure that will comply with the Google mapping requirements.  For this reason, it is probably best that this work is done by the department so that consistent routines can be established as part of a regular supply mechanism for Google mapping purposes.

We’ll coordinate with the department’s Parks and Communications teams to determine a way forward.

Thanks again for your interest.  Please let us know if you have any further questions.

Regards, NatureMaps Support

Update 5: Australian ratification of the Minamata Convention on Mercury

Media release reproduced from: https://www.aph.gov.au/About_Parliament/House_of_Representatives/About_the_House_News/Media_Releases/Mercury_falling_Treaties_Committee_examines_Minamata_Convention

Mercury falling: Treaties Committee examines Minamata Convention

Issue date: Monday, 9 August 2021

Mercury is a highly toxic heavy metal that poses a global threat to human health and the environment. The Minamata Convention creates a common platform for global action to reduce mercury’s use and impact, committing Parties to address the full lifecycle of mercury, including its safe disposal.

In the 1950s an industrial company in the Japanese seaside city of Minamata was found to have released untreated mercury waste into the adjoining saltwater bay for decades. The mercury contaminated the fish and shellfish stocks, and caused the death and poisoning of thousands of local residents. This environmental and public health catastrophe led to improved Japanese regulations and, importantly,  the establishment of the Minamata Convention.

Australia’s Joint Standing Committee on Treaties will be hearing expert evidence and reviewing Australia’s potential ratification of the Minamata Convention at a public hearing on 9 August.

Committee Chair Mr Dave Sharma MP said “Ratifying the Minamata Convention would address an important global public health risk, align Australia with our major trading partners, and provide regulatory certainty for Australian businesses”.

At its 9 August hearing the Committee will also examine the Framework Agreement between the Government of Australia and the Organisation for Joint Armament Cooperation, known as OCCAR. OCCAR is a European organisation that facilitates international cooperation in the development and procurement of defence equipment. The proposed Agreement would allow Australia to participate in OCCAR managed programmes.

Dear Mr Tsokas

RE: Wilberforce Walk shared-use pathway

Firstly, please accept my thanks to the council for undertaking and completing the excellent shared-use pathway and accompanying environmental improvements atop Brownhill Creek along Wilberforce Walk between Anzac Highway and Third Avenue in Forestville.

The shared use pathway has been complete for several months but is still not open to the public.

May I please kindly inquire as to the source of the delay in opening the pathway to the public?

Further, may I inquire as to the Council’s plans – if any – to extend the shared-use pathway and accompanying environmental upgrades alongside the full length of Wilberforce Walk and potentially beyond atop Brownhill Creek to Forestville Reserve?

Might this be something the Council would contemplate as a costed project idea it would furnish to the major political parties in the lead up to the State election, noting that such a project would sit within the marginal State electorate of Badcoe?

Thank you for your time and consideration.

Kind regards,

Mr Michael Cornish
