Buying or selling a business is a major strategic move, not just a legal process. Sierra Legal advises buyers, sellers, founders, investors and management teams through the full M&A lifecycle — from transaction strategy and due diligence through to structuring, negotiation, regulatory approvals, documentation and completion.
Our M&A team has advised on transactions across a wide range of industries including transport and logistics, technology, retail, resources and professional services. We have acted for buyers, sellers, private equity investors and management teams on deals ranging from small business acquisitions to complex multi-party corporate transactions.
We have advised on transactions involving Clark Rubber, Bingo Industries, Creative Cubes, TMX and Medibank — bringing the same depth of care and commercial focus to every matter regardless of size.
Sierra Legal provides a full suite of M&A legal services including:
From 1 January 2026, Australia's merger control regime changed significantly. Qualifying transactions must now be notified to the ACCC and cleared prior to completion. Sierra Legal has been at the forefront of advising clients on these changes. If you are planning an acquisition, we can help you determine whether your transaction requires notification and guide you through the process.
We are a boutique M&A team, but not a junior one. Our clients deal directly with experienced lawyers who know how to keep transactions moving without losing sight of the commercial objective. We are practical, responsive and calm under pressure. We also bring genuine sector familiarity across technology, logistics, professional services, retail and other mid-market industries.
We have acted on a range of public and private transactions across sectors including waste management, insurance, technology, healthcare, consumer, manufacturing and private equity.
An M&A lawyer helps clients buy, sell, merge and invest in businesses. That includes sale preparation, due diligence, structuring, drafting and negotiating transaction documents, managing confidentiality and disclosure, handling regulatory issues, and guiding the deal through to completion.
The timeline varies depending on the complexity of the transaction. A straightforward business acquisition may take 6–12 weeks from heads of agreement to completion. More complex transactions involving regulatory approvals or multiple parties can take several months.
From 1 January 2026, mandatory notification thresholds apply to certain transactions. The thresholds are based on the combined Australian revenue of the parties and the transaction value. Sierra Legal can quickly assess whether your transaction requires notification.
Vendor due diligence involves a seller commissioning a legal review of their own business before going to market. This allows issues to be identified and resolved early, reducing the risk of deal delays or price adjustments during the buyer's due diligence process.
Yes. We have experience advising on cross-border transactions and can assist with FIRB approval requirements for foreign investment into Australia.
