The ACCC publishes information on public informal merger reviews and merger authorisations on the ACCC’s mergers register.  Information about public merger reviews, timelines, and ACCC decisions are published on the ACCC’s public informal merger review register. The ACCC does not publish information on mergers that it has considered on a confidential basis, including those matters where the ACCC is satisfied that there is a low risk that the merger will be likely to substantially lessen competition and it has decided that a public review is unnecessary. These mergers are described as being ‘pre-assessed’ and can often be considered confidentially.  The ACCC also reviews applications for merger authorisation. The merger authorisation process is public and the application for merger authorisation, related submissions by the applicant and interested parties, and the ACCC’s determination, are placed on the merger authorisations public register, unless they have been excluded for example because they are confidential.
