Administration Assistant
At Cornerstone Consulting Group, we partner with leading Australian organisations to recruit exceptional talent.
We're proud to be recruiting on behalf of Pitcher Partners Adelaide.
At Pitcher Partners Adelaide, we work closely with ambitious individuals and businesses to help them grow with confidence.
As a leading mid-tier accounting and advisory firm, we're known for our strong relationships, practical advice and supportive culture.
Due to growth, an opportunity exists for an Administration Assistant to join the firm's Practice Management team in Adelaide's CBD.
This is a varied, hands-on role suited to someone who enjoys working across different areas of a business and wants to build a long-term career in professional services.
About the role
Reporting to the Office Manager and working closely with the Team Assistants, you'll provide administrative and front-of-house support across the firm.
Day to day, you will:
Provide general administrative support across the firm
Prepare, format and distribute documents, reports and presentations
Welcome clients and visitors, answer and direct calls, and provide reception cover
Coordinate meeting rooms, catering and event logistics
Manage mail, couriers, office supplies and general office upkeep
Liaise with suppliers, clients and internal staff
Assist with staff events, onboarding administration and firm initiatives
Where this role can take you
This position has a clear development pathway.
As your skills grow, you'll receive hands-on training and progressively take on Team Assistant responsibilities, including diary management, client correspondence, ASIC documentation, BAS lodgement administration and workflow coordination.




You'll also build proficiency in systems such as Xero, Practice Ignition, Now Infinity and FYI Docs, setting you up for a long-term career in practice support.
What success looks like
Success in this role is about more than completing administrative tasks.
It's about being a reliable team member who is adaptable, takes initiative and is always willing to help where needed.
You'll become a trusted support person across the firm, working collaboratively with Reception, the Office Manager, Team Assistants and client-facing teams to keep the business running smoothly.

The ability to work independently and as part of a team
Experience in an accounting or professional services environment, exposure to practice management software, or a Certificate III or IV in Business Administration would be a bonus, but none are essential.
