Mr Andrew Harrison
General Manager
KPM Legal Partners
Level 22, 1 Macquarie Place
Sydney, NSW 2000

Dear Mr Harrison,

When I discovered that KPM Legal Partners is seeking a Senior Administrator to oversee office operations across Sydney and Melbourne offices while managing administrative teams and optimising business processes supporting 85+ legal professionals, I recognized this was precisely the opportunity I’ve been working toward. As someone who served as Senior Administrator at Thomson & Associates—managing office operations for 120+ staff across two locations with $2.8 million annual operational budget achieving 98% on-time delivery of administrative services and 4.7/5.0 stakeholder satisfaction rating, supervising team of eight administrators providing performance management, training, and workflow coordination that improved team productivity by 34% and reduced administrative errors by 72%, implementing digital transformation initiatives including document management system migration, meeting room booking automation, and expense management platform reducing paper usage by 89% and administrative processing time by 45%, coordinating executive support for five partners including complex diary management, international travel arrangements, and board meeting preparation maintaining zero missed commitments across 18-month period, and leading office relocation project managing 15 vendors, coordinating 40+ workstations, and completing move with zero business disruption under budget by 8%—I’m thrilled at the prospect of combining operational excellence and team leadership for Sydney’s premier commercial law firm.

Over the past seven years as a Senior Administrator working throughout Sydney’s professional services sector, I’ve repeatedly delivered results that match perfectly with your needs. I’ve managed comprehensive office operations including facilities management, vendor relationships, procurement processes, and health and safety compliance ensuring smooth daily operations supporting fee-earning professionals to focus on client service and revenue generation, supervised and developed administrative teams providing coaching, performance reviews, skills training, and succession planning that reduced staff turnover from 38% to 12% and improved team capability scores by 41% as measured through competency assessments, implemented process improvements and automation solutions streamlining workflows including invoice processing, client onboarding, document production, and records management delivering $180,000 in annual cost savings and 520 hours in reclaimed productivity, provided executive support to C-suite and senior leadership including diary management, correspondence, meeting coordination, presentation preparation, and confidential matter handling maintaining discretion and professionalism across sensitive business matters, managed complex projects including office fit-outs, technology implementations, policy development, and compliance initiatives delivering on-time, on-budget outcomes with comprehensive stakeholder communication and change management, and maintained financial oversight including budget preparation, expense tracking, purchase order management, and vendor payment processing ensuring fiscal responsibility and accurate financial reporting for monthly management reviews. My background spanning operations management, team leadership, executive support, and project coordination has shown me that exceptional senior administration merges organisational capability with strategic business understanding—precisely what you require for operational efficiency and professional excellence.

What really attracts me to KPM Legal Partners is your reputation for client service excellence and your commitment to creating efficient operational infrastructure supporting legal professionals to deliver outstanding outcomes. I hold Advanced Diploma of Business Administration from TAFE NSW, Certificate IV in Project Management Practice, and completed professional development in change management, process improvement methodologies, and leadership development through Australian Institute of Management. I’m proficient with Microsoft Office 365 including SharePoint and Teams, experienced with practice management systems including LEAP and ActionStep, and knowledgeable about workplace health and safety compliance, privacy requirements under Privacy Act, and records management best practices. One achievement I’m particularly proud of is leading comprehensive process review and improvement programme across administration function by mapping existing workflows identifying 23 bottlenecks and inefficiencies, consulting with stakeholders across all departments to understand pain points and requirements, implementing standardised procedures with automation where appropriate including template libraries, approval workflows, and automated reminders, creating comprehensive training materials and delivering upskilling sessions for 35 staff members, and establishing continuous improvement framework with regular reviews and feedback mechanisms, which reduced average invoice processing time from 8 days to 2 days, improved document turnaround time by 56%, increased first-time accuracy rate from 81% to 97%, and generated $145,000 in annual efficiency savings earning ‘Operational Excellence Award’ and establishing model approach adopted across three other business units. I’m convinced that Senior Administrators aren’t merely task coordinators managing schedules—we’re operational leaders who create efficient systems enabling business success, people managers who develop high-performing teams, and strategic partners who anticipate needs and implement solutions that drive organisational effectiveness and competitive advantage.

I’d welcome the chance to discuss how my proven ability to manage operations, lead teams, and drive continuous improvement can enhance KPM Legal Partners’ operational efficiency and support your growth objectives. Thank you for reviewing my application, and I look forward to connecting with you soon.

Kind regards,

Michelle Chen

What to Include in a Senior Administrator Cover Letter (Australia)

Your Senior Administrator cover letter needs to follow a leadership-focused structure that showcases both operational expertise and team management capability:

Right vs Wrong Example

Right Opening: “When Macquarie Group announced their requirement for a Senior Administrator to manage operations for their wealth management division supporting 150+ financial advisers and client service teams while leading administrative staff and implementing efficiency improvements across Sydney CBD and Parramatta offices, I instantly recognized where my background—overseeing office operations for financial services firm with 180+ employees managing $4.2 million operational budget achieving 99% service delivery compliance and 4.8/5.0 client feedback rating, leading team of 12 administrators providing performance management, succession planning, and professional development that improved retention by 43% and team productivity by 38%, and implementing workflow automation solutions including digital document management, client onboarding systems, and reporting dashboards reducing processing time by 52% and enabling adviser teams to focus on revenue-generating activities—could support your operational excellence standards while delivering the seamless administrative infrastructure your high-net-worth clients expect.”
Wrong Opening: “I am writing to apply for the Senior Administrator position that was advertised on Seek. I have administration experience and good organisational skills. I believe I would be a good fit for this role at your company.”
