Ms Jennifer Williams
Chief Information Officer
National Retail Group
Level 14, 100 Market Street
Sydney, NSW 2000
Dear Ms Williams,
When I saw that National Retail Group is modernizing its infrastructure to support 200+ retail locations while migrating to hybrid cloud, I knew this was exactly the challenge I’ve been preparing for. As someone who led a similar transformation at Australian Logistics Corp—migrating 80% of on-premises workloads to Azure while reducing infrastructure costs by 32% and achieving 99.97% uptime—I’m excited about the opportunity to deliver the reliable, scalable platform your digital retail strategy demands.
Over the past seven years managing infrastructure teams across Sydney’s retail and logistics sectors, I’ve consistently delivered outcomes that align perfectly with your requirements. I transformed TechRetail’s aging infrastructure by implementing a hybrid cloud architecture, modernizing our network backbone from 1Gbps to 10Gbps, and establishing a disaster recovery solution that reduced RTO from 48 hours to 4 hours. My experience leading technical teams of 12+ engineers while managing $4.5M infrastructure budgets has taught me that successful IT infrastructure management is equal parts technical vision and operational discipline—exactly what you need for this multi-site modernization.
What really draws me to National Retail Group is your commitment to leveraging technology for competitive advantage. During my Bachelor of Information Technology at UTS and subsequent certifications in Microsoft Azure (Azure Solutions Architect Expert) and AWS (Solutions Architect Associate), I developed expertise in designing resilient, cost-effective infrastructure. I’m passionate about proving that infrastructure isn’t just a cost center—it’s a strategic enabler that drives business agility, customer experience, and operational efficiency.
I’d love to discuss how my track record of delivering complex infrastructure projects on time and under budget can contribute to National Retail Group’s digital transformation ambitions. Thank you for considering my application, and I look forward to the opportunity to speak with you soon.
Kind regards,
Marcus Chen

What to Include in an IT Infrastructure Manager Cover Letter (Australia)
Your IT Infrastructure Manager cover letter needs to follow a strategic structure that demonstrates both technical leadership and business alignment:
- Contact Details
- Salutation (Dear Hiring Manager or name)
- Opening paragraph – your hook and intent
- Middle – why you’re the best fit (skills + experience)
- Closing – call to action + sign off
Right vs Wrong Example
Right Opening: “When Commonwealth Bank announced its data center consolidation initiative affecting 2,000+ servers and 500TB of critical data, I immediately saw an opportunity where my experience leading a similar migration—completing the project 3 weeks ahead of schedule while maintaining zero unplanned downtime and reducing annual operating costs by $1.8M—could support your ambitious infrastructure modernization goals.”
Wrong Opening: “I am writing to apply for the IT Infrastructure Manager position that was advertised on Seek. I have experience managing IT infrastructure and I believe I would be a good fit for this role at your company.”
Entry-Level IT Infrastructure Manager Cover Letter Tips
- Focus on progression from senior engineer/architect to team leadership

Entry-Level Cover Letter Sample for IT Infrastructure Manager
Right Entry-Level Approach: “While serving as Senior Infrastructure Engineer at Digital Solutions Australia for the past four years, I’ve progressively taken on leadership responsibilities including mentoring three junior engineers, leading our VMware to Hyper-V migration project affecting 120 virtual machines, and managing vendor relationships with Microsoft, Cisco, and Dell EMC totaling $800K annually. I also served as acting Infrastructure Manager during my manager’s extended leave, overseeing daily operations for our 8-person team and presenting infrastructure roadmap updates to the IT Steering Committee. This experience taught me that effective infrastructure leadership combines technical depth with strategic communication—skills I’m eager to apply in a formal management role.”
Wrong Entry-Level Approach: “I’ve been a senior infrastructure engineer for a while and I think I’m ready to be a manager. I’m good with technology and I work well with people. I really want this opportunity to take the next step in my career and lead a team. Please consider me.”
