5 Steps to Build a Freight Contingency Plan for Australian Importers

A freight contingency plan supports Australian importers when vessel schedules slip, containers are rolled, or customs holds delay clearance. Sea-Intelligence reported that global schedule reliability climbed to 62.4% in April 2026, yet more than one in three vessels still arrived off schedule. This disruption creates a real risk of missed replenishment windows, urgent freight spend, and delayed customer orders. 

Without a documented fallback plan, a single delayed shipment can disrupt order flow, increase freight costs, and force costly last-minute decisions. This article sets out five practical steps to build a plan that reduces exposure.

Summary of How to Build a Freight Contingency Plan

A freight contingency plan supports Australian importers in minimising disruption from vessel delays, rolled containers, customs holds, and carrier issues. Effective plans pinpoint weak points in the inbound supply chain, set clear action triggers, line up backup freight options, and hold buffer stock for delayed replenishment. 

The five steps below outline how to build a plan that protects order flow and avoids costly last-minute decisions. 

1. Map every supplier, carrier, port, customs broker, and delivery handoff to identify single points of failure across the inbound chain.
2. Secure backup carriers and alternate routes before a disruption, so urgent stock can be shipped without opening new accounts during a delay.
3. Set measurable activation triggers, such as a missed vessel cut-off or a shipment running more than 72 hours behind schedule.
4. Prepare communication templates for customers, suppliers, and internal teams so updates can be issued as soon as the contingency plan is activated.
5. Hold buffer stock in a secondary fulfilment location so orders can still be picked and dispatched if one inbound lane stalls.

Couriers & Freight's warehousing and fulfilment network gives importers a place to hold buffer stock in a secondary location.

Why Australian Importers Need a Freight Contingency Plan

Australian importers are exposed to disruption at several points between overseas origin and final delivery. The highest-risk points are inbound delays, carrier capacity shifts, and dependence on a single supplier or lane. 

Each can interrupt replenishment, force spot-rate buying, or leave customer orders waiting on stock that has not landed.

• Inbound delays: Sea-Intelligence reported that the average delay for late vessel arrivals was 5.28 days in 2024, with schedule reliability in the 50% to 55% range.
• Carrier capacity issues: Drewry’s World Container Index rose 7% in the week to 20 June 2024, with the composite index reaching $5,117 per 40-foot container as congestion and Red Sea disruption tightened capacity.
• Single-route dependency: If your inbound stock relies on one lane, one service, or one carrier group, a disruption can leave you with no immediate fallback. The Red Sea crisis forced major carriers to divert services around the Cape of Good Hope through 2024. The added transit time and disrupted normal Asia-Europe and related network rotations. This disruption is a reminder that importers relying on one route structure can be left exposed when schedules change or capacity tightens. 

5 Steps to Build a Freight Contingency Plan

Step 1: Map Your Import Supply Chain

Start by mapping every handoff between the overseas supplier and the Australian customer. This includes the factory, origin port, ocean or air carrier, Australian arrival port, customs broker, transport provider, warehouse, and final delivery channel. 

The point is to identify where one supplier, one carrier, one lane, or one site controls the shipment of stock. 

For example, an apparel importer using a single ocean carrier on a Ningbo-to-Melbourne lane may have no fallback if the sailing is rolled or the service is blanked for a week. A useful map should show each dependency clearly enough that you can nominate a backup route, provider, or stock location for each weak point. 

What to document in your contingency plan: 

• Supplier name and origin port
• Incoterms
• Usual carrier and lane
• Average transit time
• Customs broker
• Warehouse handoff and final delivery path
• Key Stock Keeping Unit (SKU) dependencies
• Backup route or provider for each critical point

If a fast-moving product line depends on one supplier and one lane, the risk should be visible in the plan before the shipment is delayed. 

Step 2: Line Up Backup Carriers and Routes

A freight contingency plan only works if the fallback is arranged before the delay happens.

This means opening backup carrier options in advance, confirming which lanes they cover, and deciding which SKUs are worth moving by air if ocean freight slips. The goal is to avoid scrambling for quotes after a shipment has already missed its cut-off. 

Importers typically handle this by pre-approving alternate carriers or using a freight platform that provides access to multiple sea and air freight options from one place. If a sea shipment of electronics parts is delayed by two weeks, the operations team can shift urgent cartons to air rather than start a fresh quoting process in the middle of the disruption. 

Couriers & Freight is one option for this setup, allowing importers to compare and book multiple sea and air carrier options through one platform.

Step 3: Set Clear Activation Triggers

Importers typically handle this by pre-approving alternate carriers or using a freight platform that provides access to multiple sea and air freight options from one place. Set triggers around measurable events rather than broad concerns.

It might be a shipment missing its booked vessel, a container not being available for collection within a set time, or an Estimated Time of Arrival (ETA) moving beyond the last safe replenishment date for a key SKU. 

Sea-Intelligence reported that the average delay for late vessel arrivals was still more than five days in late 2024, which is a useful reminder that delays need to be measured, not guessed. 

What to document in your contingency plan:

• Trigger event
• Escalation owner
• Fallback action
• Customer or internal communication required. 

Useful triggers might include a vessel being rolled to the next sailing or a container not being collected within 48 to 72 hours of availability. Other triggers include a customs hold extending beyond a set threshold or an urgent SKU being projected to stock out before the next replenishment lands. 

For example, you might activate the plan if a shipment misses port pick-up by more than 72 hours, then divert 15% of urgent stock to air freight. 

Step 4: Prepare a Communication Plan

Once the contingency plan is activated, the next question is who needs to know and what they need to be told. Prepare templates for customers, suppliers, sales staff, warehouse teams, and finance before a disruption occurs.

Each template should state the shipment affected, the expected delay, the stock or order impact, and the action being taken. 

Keep them in a shared location so the right team can send them immediately without waiting to draft updates from scratch.

If a customs hold delays an inbound container, the customer-facing team should already have a template ready to explain revised dispatch timing, while procurement can send a separate update to the supplier and internal stakeholders. This saves time during a disruption and helps each team communicate consistently from the same facts. 

Step 5: Hold Buffer Stock in a Secondary Location

To keep orders flowing when an inbound lane stalls, hold part of your inventory in a secondary fulfilment location. The stock acts as a buffer while the delayed shipment is still in transit, helping maintain customer fulfilment until replenishment arrives.

The setup matters: the stock needs to be physically stored in a facility that can release it against live orders, not just counted as safety stock on a spreadsheet.

For example, if one of your fastest-moving SKUs is delayed on the water, reserve stock in a second fulfilment site can still be picked, packed, and dispatched. This keeps orders flowing while the inbound replenishment is waiting to land or clear. 

Importers can manage this internally or through a warehousing and fulfilment provider that can hold and release reserve stock when the primary inbound shipment is delayed. 

Couriers & Freight’s warehousing and fulfilment service is one option for setting up secondary stockholding.
