I am honoured to be appointed Australia’s Ambassador for Arms Control and Counter-Proliferation. As global risks rise, so must our resolve. I look forward to working with partners to champion strong non-proliferation standards, effective arms control and practical disarmament.

The Comprehensive Nuclear-Test-Ban Treaty has underpinned a decades-long global norm against nuclear testing that benefits all states. It’s in every state’s interest to maintain it. That was my message at today's CTBT meeting at the UN as we push for the Treaty’s entry into force

Australia welcomes the OPCW Executive Council’s decision to reinstate Syria’s rights and privileges under the CWC. As a co-sponsor of this historic decision, Australia supports efforts that strengthen the integrity of the Convention and a world free of chemical weapons. #OPCW
The OPCW’s Executive Council today adopted a decision to reinstate the rights and privileges of Syria under the #ChemicalWeaponsConvention, recognising the progress made by the Syrian authorities in addressing the chemical weapons programme inherited by the former regime.
The Council also adopted three related decisions to advance the closure of the Syrian chemical weapons dossier:
- a chemical weapons destruction verification plan for Al Qutayfah
- two separate facility agreements for the systematic verification of the Al Qutayfah and Homs chemical weapons storage facilities

Congratulations to Tonga on ratifying the CTBT. This marks an important milestone for our region, with all countries in the Pacific now party to the Treaty. Australia looks forward to working with Tonga to strengthen the global ban on nuclear test explosions.
🌏 Tonga has signed and ratified the #CTBT, completing universalisation of the Treaty
across the Pacific region. The ceremony took place on Tuesday, 7 July at UN Headquarters in New York, a landmark moment for 🇹🇴, for the Pacific, and for the global effort to ban nuclear test explosions. The Treaty now counts 188 States Signatories and 179 ratifying States.

The Australia Group’s role in in fighting the spread of chemical and biological weapons is more important than ever. Pleased to promote the AG to regional partners last week at the #PSI meeting and the benefits states enjoy through unilateral adherence or participation in the AG
Western Hemisphere cooperation through #PSI was on display in Buenos Aires last week where officials discussed proliferation threats, interdictions, maritime awareness, proliferation financing, cargo handling, ship boarding and participated in a lively table top exercise.

Australia is disappointed that the 11th NPT Review Conference did not reach consensus despite best efforts of many. Sincere thanks to @dohungviet and UNODA. Despite the lack of formal outcome, there is strong commitment to the NPT and its essential role.
