Step 1 — Confirm 311313 is the right code
ANZSCO 311313 covers biosecurity / quarantine work — inspecting incoming international passengers and their luggage at airports / seaports, inspecting imported cargo (containers, breakbulk, mail) for pest / disease / contamination risk, treatment supervision (fumigation, irradiation, cold treatment, heat treatment), live animal / plant import facility inspections, post-entry quarantine compliance, regional surveillance (fruit fly, varroa mite, fire ant, Khapra beetle, foot-and-mouth disease readiness), pest / disease detection in farms / nurseries / packing sheds, weed and invasive species programs, and emergency biosecurity response participation.
If you have a Bachelor of Veterinary Medicine and your work is primarily clinical animal-disease surveillance / regulation, you may also fit 234711 Veterinarian.

Step 4 — Choose a visa pathway
Subclass 189 / 190 / 491
189 if 311313 is on MLTSSL — confirm at EOI. 190 / 491 are realistic given the recruitment cycles of DAFF and state biosecurity agencies. Strong nomination markets:
- NSW — Sydney airport / Port Botany / parcel facilities, regional NSW DPI biosecurity.
- Vic — Melbourne airport / Webb Dock, Agriculture Victoria biosecurity.
- QLD — Brisbane airport / Port of Brisbane, Cairns airport (north QLD biosecurity hotspot), Biosecurity Queensland, regional banana / sugar / fruit fly work.
- WA — Perth airport / Fremantle Port, DPIRD WA biosecurity (particularly for unique WA pests).
- SA — Adelaide airport / Port Adelaide, PIRSA biosecurity (fruit fly).
- TAS — Hobart / Launceston / Devonport ports, NRE Tas biosecurity (foot-and-mouth, fruit fly readiness).
- NT — Darwin airport / Darwin port (top-end biosecurity, regional surveillance).
Subclass 186 / 494 / 482
Main 311313 employers are government — DAFF (Australian Government) and state biosecurity agencies. Private-sector sponsorship is rare. DAFF runs continuous APS-level recruitment for biosecurity officers (APS3 / APS4 / APS5 grades).
Some Approved Arrangement / quarantine treatment service providers (Genera, Sundoc, Bayer Crop Science fumigation services, Asia-Pacific Fumigation, Steritech irradiation) provide private-sector adjacent roles.
