Below is a concise list of top-rated digital-transformation providers that operate in Australia — grouped by large global consultancies, major local players, and highly rated Australian boutiques/agencies. For each I’ve noted their core strengths and linked a source showing their Australian capability.

Large global consultancies with strong Australia operations

• Accenture (Australia) — end-to-end digital strategy, cloud, AI, SAP and large-scale program delivery; active M&A and local hires to scale Australian capability. (newsroom.accenture.com, reuters.com)
• Deloitte Digital (Deloitte Australia) — digital strategy, customer experience, marketing tech and large transformation programs across sectors. (campaignbrief.com)
• PwC Australia — digital transformation strategy, cloud & data, and industry transformation programs with local delivery teams. (pwc.com.au)
• KPMG Australia — digital services and innovation with focus on data, automation and organisational change. (kpmg.com)
• EY (Ernst & Young) Australia — digital strategy, transformation platform and large program execution (including EY-Parthenon and EY transformation offerings). (ey.com)

Major Australian / locally headquartered players

• Telstra Purple (Telstra’s consulting arm) — Australian-owned large capability in cloud migration, Microsoft/AWS practices, network + transformation services. Good choice when local ownership and network capability matter. (purple.telstra.com.au, telstrainternational.com)
• First Focus (Australian MSP & services) — growing local managed services and digital capability through acquisitions; useful for mid-market to enterprise managed + transformation work. (en.wikipedia.org)

Highly rated Australian boutiques and digital agencies (good for experience design, product-led transformation, faster delivery)

• Luminary (Melbourne) — listed highly in Australian digital-transformation consultant rankings (Clutch). (clutch.co)
• Other Clutch-ranked Australian boutiques (examples) — Emote Digital, Human Digital and similar firms are top-rated for design-led and experience-focused transformations. See Clutch Australia rankings for up-to-date client-review based lists. (clutch.co)

Notes on choosing the right partner

• Use global consultancies for very large, cross-country programs, heavy systems integration (ERP/SAP, large cloud migrations), or when you need scale and deep industry playbooks. (newsroom.accenture.com, campaignbrief.com)
• Use Telstra Purple, local MSPs or Cognizant/Infosys when you want strong onshore delivery, telco/network integration, or local data-sovereignty/managed services. (purple.telstra.com.au, infosys.com)
• Use boutiques (Luminary, Emote, Human Digital, etc.) for product/UX-first transformations, rapid prototyping and customer-experience redesigns — check client reviews and sector experience on directories like Clutch. (clutch.co)

If you want, I can:

• produce a short shortlist (2–4 firms) tailored to a specific industry (banking, government, retail, healthcare) or transformation type (ERP migration, AI, customer experience), or
• pull the latest client-review rankings (Clutch/GoodFirms) for Australian digital-transformation firms and deliver a ranked shortlist with pricing bands.

Which (if any) of those would you like me to expand into a tailored 2–4 vendor shortlist?
