Our Story
Group One Cleaning was founded by Director Anthony Zissis with a clear vision – to build a national cleaning company that industrial and commercial clients across Australia could genuinely rely on. From the first contract to a growing national footprint, the company has been built on straightforward principles: show up, do the work properly, and keep clients' facilities clean, safe, and compliant.
Today, Group One Cleaning services a wide range of facility types including industrial sites, warehouses, factories, commercial offices, retail centres, construction sites, healthcare and government facilities, educational campuses, and strata properties. Operating nationally, the company has grown by earning the trust of facility managers and procurement teams who need a contractor that can scale with their requirements and hold itself to a consistent standard on every site.
Our Mission
"To provide reliable, professional cleaning solutions that help Australian businesses maintain safe, clean and productive environments."
Group One Cleaning's mission drives every decision – from the teams they recruit and train, to the equipment they invest in, and the standards they hold on every contract. This mission is not aspirational language; it is the operational benchmark every client engagement is measured against.
Core Values
The principles that guide every engagement, every team, and every outcome.
Professionalism
We represent our clients' facilities with care, presenting clean and compliant sites that reflect well on their operations.
Reliability
When we commit to a schedule, we honour it. Consistent attendance and predictable outcomes define how we work.
Trust
Long-term client relationships are built through honesty, transparency, and holding ourselves accountable to the standards we set.
Safety
Safety is non-negotiable. Every team member operates under strict OH&S protocols that protect people and property on every job.
Compliance
We maintain full insurance coverage and comply with all relevant workplace health and safety regulations across Australian jurisdictions.
Results Driven
Our measure of success is a genuinely clean, safe, and well-maintained facility – not just a completed checklist.
Commitment To Safety
Safety is at the foundation of how Group One Cleaning operates. Every job, regardless of size or industry, is carried out under a structured set of OH&S protocols designed to protect our team members, your employees, and your physical facility.
Our safety framework includes:
– Site-specific risk assessments before commencement
– Safe Work Method Statements (SWMS) for all high-risk activities
– Full PPE compliance and provision for all crew members
– Chemical handling and storage procedures aligned with Australian standards
– Regular team safety briefings and toolbox talks
– Incident reporting and continuous improvement processes
Group One Cleaning is fully insured and maintains current public liability and workers compensation coverage. We operate in full compliance with Work Health and Safety (WHS) legislation across all Australian states and territories.
Commitment To Quality
Delivering a clean facility once is straightforward. Delivering it consistently – across every visit, every team, every location – is where Group One Cleaning differentiates itself. Our quality assurance framework is built to eliminate variability and hold every site to the same standard, regardless of scale.
Our quality processes include:
– Pre-clean and post-clean site inspections on all scheduled contracts
– Digital sign-off and reporting for accountability on each visit
– Dedicated supervisors assigned to ongoing commercial contracts
– Regular client feedback reviews and service audits
– Standardised cleaning specifications per facility type
– Prompt rectification procedures for any reported deficiencies
Our goal is not simply to meet a specification – it is to ensure every client can walk into their facility and feel confident it has been done properly.
National Service Capability
Group One Cleaning operates nationally, with the infrastructure and team capacity to service industrial and commercial clients across all Australian states and territories – New South Wales, Victoria, Queensland, Western Australia, South Australia, Tasmania, the ACT, and the Northern Territory.
