Get your MARS voyage status through an API

What you can build on MARS

• Get a voyage's biosecurity status

  Build this

  Opens the Voyage Details screen for one vessel and voyage number and reads the BSD traffic lights, inspections completed and applications received.

  Takes

  IMO number, voyage number

  Returns

  Vessel name, traffic light per BSD section, inspections completed, applications received

• Search reports and applications

  Build this

  Runs the Report, application or service request search for a vessel's IMO number and date range and reads the results grid.

  IMO number, date from, date to

  Returns

  Vessel, voyage number, application type, status, date submitted

• List your agency's port visits

  Build this

  Port (optional), date from, date to

  Returns

  Vessel, IMO number, voyage number, port, visit status, arrival, berth and departure date and time

• Load a PAR from an offline form

  Build this

  Loads the XML data file a master sent from the MARS offline PAR form into MARS and submits the pre-arrival report.

  Takes

  XML data file from the offline form

  Returns

  Vessel, IMO number, voyage number, application type, status, date submitted

Automate MARS with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• Expected arrivals that still have no PAR

  Build this

  Starts

  Every day at 7:00 Australia/Sydney

  Step 1

  List your agency's port visits with an expected arrival in the next 4 days.

  Step 2

  For each vessel, search reports and applications for a PAR with status Complete.

  Step 3

  Keep the visits that have none.

  Step 4

  Email you each one with vessel, IMO number, voyage number, port and expected arrival.

• BSD traffic light changes for active voyages

  Build this

  Starts

  Every hour

  Step 1

  For each vessel and voyage number you list, get the voyage's biosecurity status.

  Step 2

  Keep the BSD sections whose traffic light changed since the last run.

  Step 3

  Post vessel, voyage number, section, old and new colour to your webhook.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get a voyage's biosecurity status” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "online.agriculture.gov.au/get_voyage_biosecurity_status",
    "input": {
      "imo_number": "9712345",
      "voyage_number": "N245S"
    }
  }'

{
  "status": "completed",
  "data": {
    "vessel_name": "Northwind Trader",
    "imo_number": "9712345",
    "voyage_number": "N245S",
    "bsd_traffic_lights": {
      "approval_to_berth": "green",

    },
    "inspections_completed": "Vessel biosecurity inspection, Brisbane, 2026-11-10",
    "applications_received": [
      {
        "type": "PAR",
        "status": "Complete",
        "submitted": "2026-11-07T09:42:00+10:00"
      }
    ]
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

MARS’s own options

The department provides MARS as a web portal where vessel masters and shipping agents submit pre-arrival documents and view a vessel's status. Its MARS pages document no API. Masters without internet access can fill in offline PDF forms and send the XML data file to their agent, who loads it into MARS.

Read on November 12, 2026: MARS and the Vessel Compliance Scheme, MARS offline forms, MARS User Guide (PDF).

Signing in to MARS

MARS is reached through the department's online services portal with a DAFF Security Account: a User ID and a password of 10 or more characters, then an approved MARS access request. You sign in once with your own account. The login is sealed with AES-256, code and AI agents never see it, and when the session expires the product signs back in.

Worth knowing

One vessel per master's User ID

A master's User ID is linked to one vessel at a time and must request MARS access again for a new vessel. An agency user's Visit search defaults to the agency's own visits.

The PAR window is 96 to 12 hours

A commercial vessel's pre-arrival report must be given 96 to 12 hours before arrival in Australian territory.

Only the current BSD is kept

The BSD is generated automatically and version controlled, and the BSD Details tab shows only the current version. Each section's light shows the most severe colour among its conditions.

Invoices come after departure

The department's FMIS issues one invoice per port visit within 24 hours of the vessel departing. MARS shows a summary of invoices, un-invoiced charges and payment status.
