Kirrawee, New South Wales, Australia The Property Investment Store Full time $90,000 - $120,000 per year
Senior Office Administrator (Office Manager) – SDA Management Australia

Full-time | 9:00am–5:00pm, Monday–Friday | Onsite in Kirrawee (Sutherland Shire)

SDA Management Australia (SDAMA) is a specialist property management company in the NDIS SDA sector. We're proud of our high standards, supportive culture, and the meaningful impact we make for participants with disabilities across Australia.

The Role

We're looking for a driven, hands-on Senior Office Administrator to be the glue that holds our office together. You'll run day-to-day operations, create documents and systems, liaise with stakeholders nationwide, and keep everything humming.

What You'll Do
  • Work as a true team player, supporting colleagues and fostering a collaborative, positive office culture.
  • Own end-to-end office management (calendars, inboxes, supplies, contractors, compliance).
  • Create, document and continuously improve procedures and SOPs so the office runs smoothly.
  • Proactively solve problems, triage issues, and implement practical solutions.
  • Prepare professional documents, reports, and templates for internal and external use.
  • Liaise with staff, property owners/investors, and SIL providers around Australia.
  • Support leadership with scheduling, reporting, and communications.
  • Pitch in where needed—everyone on our team helps each other.
About You
  • A natural all-rounder and team player who's comfortable getting your hands dirty.
  • 3+ years' office admin/operations experience (real estate experience a big plus, not essential).
  • Proven track record in creating and rolling out office systems/procedures.
  • Strong written and verbal communication; high attention to detail.
  • Tech-savvy (MS Office/Adobe, AI, PropertyMe or similar is a bonus).
  • Calm under pressure, organised, and solutions-focused.
Why SDAMA?
  • A genuinely supportive, fun team that backs each other.
  • Purpose-driven work in a rewarding space supporting people with disabilities.
  • Competitive remuneration, commensurate with experience.
  • Stable, Monday–Friday hours in our Kirrawee office.
