A senior-only practice for institutions that cannot afford to be misread.
Lewis & Grey International / Sydney and Austin
Lewis & Grey International advises sovereign governments, multilateral organisations, regulated institutions and the people who lead them, in more than forty markets.
Precision over volume.
We do not chase news cycles. Our attention is on the information environment that governments and institutions actually work in, which is smaller and slower than the daily feed and a great deal more consequential.
Results over profile.
Every engagement begins with a confidential scoping briefing. Results are shared privately with prospective clients and are not published, which is why the file below reads as it does.
- Client
- Name withheld
- Sector
- Withheld
- Mandate
- Discussed at briefing
- Outcome
- Shared in private
- Team
- Senior advisers only. Biographies are provided at the briefing.

The record is now written by search, and read by people who never say they looked.
The information environment includes the first page of Google and the answers given by AI assistants. Both are taken as fact, and both can be corrected by someone who understands how they are assembled.
Two offices, and one of them is always awake.
