Office Administrator based at Wetherill Park

Join a locally-led team with 40 years of building excellence.

G.J. Gardner Homes Sydney Liverpool is a family-owned and operated business, blending deep-rooted values with high-level professional expertise. With a history in South West Sydney dating back to 1962, we specialise in a wide range of projects—from knockdown rebuilds and vacant site builds to high-end custom homes. We are dedicated to providing the reliability and local knowledge needed to make our clients' dream homes a reality.

The Opportunity

Based entirely at our Wetherill Park office, you will be the heartbeat of our operations. This is a 100% in-office position that blends professional front-of-house management with technical construction administration. From the moment you welcome a new customer to the final coordination of an Occupation Certificate, you will drive the schedule and ensure a seamless journey for every family we build for. If you are a detail-oriented professional with experience in residential construction who thrives on variety and process efficiency, this is the perfect career step for you.

Perks You'll Love

• Flexible Working: Enjoy consistent office hours, generally 8.30am – 4.30pm, Monday to Friday, based in our Wetherill Park office. For the right fit, we are willing to consider a 9-day fortnight.

• Expert Support: Work alongside an experienced leadership team in an environment that truly understands every facet of the build.

• Supportive Culture: Join a close-knit, collaborative team where you have the ability to help train and mentor junior staff as the office grows.

• Stability & Legacy: Represent a brand with over 40 years of building excellence and a team with deep-rooted local history.

What You'll Be Doing

• Front-of-House: Greet customers, trades, and suppliers with professionalism; manage incoming calls and ensuring the office and showroom is presented to a high standard.

• Construction Administration: Manage administrative duties through to completion, including sending progress claims, working closely with site managers, and supporting supervisors with administrative tasks.

• Compliance & Safety: Manage on-site OHS requirements and safety audits. Liaise with trades and suppliers to ensure all compliance certificates are received and confirm certifier inspections have been passed and saved in the system.

• Contract Variation Management: Prepare contract variations for additional site costs or upgrades in construction as requested and meet with clients for final sign-off and document signing when required.

• Project Compliance & Approvals: Manage the end-to-end lodgement of DA/CC/CDC, BYDA, HBCF, and utility applications; coordinate OC checklists and council compliance follow-up to obtain final OC permits.

• Administration: Coordinate handovers and the 90-day maintenance period by booking tasks and liaising with owners and trades; enter invoices into Xero and check for accuracy; manage social media, general office admin, and the ordering of brochures, site fence wraps, and signage.

What You'll Bring

• Construction Admin Experience: Proven experience in construction administration is essential. You must understand the residential build process from deposit to completion.

• Technical Accuracy: A high level of detail to review construction invoices, audit certifier checklists, and ensure all site documentation and safety packs are accurate and up to date.

• Organisational Excellence: The ability to implement procedures to enhance workflow efficiency, manage storage and site signage, and juggle multiple tasks.

• Communication Skills: A professional manner used to assist clients with questions or concerns during the build, liaise with banks for funding approvals, and build strong relationships with our loyal trade and supplier network.

• Tech Proficiency: Comfortable using Xero, Google Suite, and builder portals/CRM systems.
