Plant Health Certificate Australia: What It Is & How to Get One
The Plant Health Certificate Confusion
If you’ve ever tried to ship plants interstate in Australia, you’ve likely encountered the term “Plant Health Certificate” or “PHC”. For most plant lovers and small-scale growers, this government requirement can be confusing, time-consuming, and expensive to navigate.
The reality is simple: if you want to send plants to Western Australia, Tasmania, or the Northern Territory, you need a Plant Health Certificate. But getting one isn’t as straightforward as downloading a form or ticking a box online. It requires government inspection, chemical treatments, official documentation, and strict timing.
This guide breaks down everything you need to know about Plant Health Certificates in Australia—what they are, when you need them, how to get them, and how Paradise Distributors can handle the entire process for you.
What is a Plant Health Certificate?
A Plant Health Certificate (PHC) is an official government-issued document that certifies your plants have been inspected by a qualified inspector and found to be free from pests, diseases, and other biosecurity risks. It proves that your plants meet the strict quarantine requirements of the destination state.
Think of it as a “passport” for your plants. Just as you need documentation to cross international borders, your plants need a PHC to cross certain state borders in Australia.
The certificate includes:
- Details of the plants being shipped (species, quantity, origin)
- Inspection date and inspector details
- Treatments applied (insecticides, fungicides, etc.)
- Certification that plants meet destination state requirements
- Validity period (typically 14 days from issue)
Types of Plant Health Documentation
Plant Health Certificate (PHC)
The standard certificate required for most interstate plant shipments. Issued after government inspection and treatment. Valid for 14 days. Required for all commercial and private plant consignments to WA, TAS, and NT.
Plant Health Assurance Certificate (PHAC)
A streamlined certificate available to ICA-accredited businesses who maintain their own quality assurance systems. Faster and cheaper than standard PHC, but requires significant ongoing compliance investment. Only viable for high-volume commercial nurseries.
Import Permit
Required for certain high-risk plant species or host material (soil, cutting substrate). Obtained separately from the destination state’s agriculture department before shipping. Some rare plants require both an Import Permit AND a PHC.
When You Need a Plant Health Certificate
Not all interstate plant shipments require a PHC. Here’s the breakdown:
✅ PHC Required For:
- Western Australia (WA) – All plants must have a PHC AND comply with WAOL (WA Organism List) restrictions. WA has Australia’s strictest biosecurity laws.
- Tasmania (TAS) – All plants require a PHC issued by Biosecurity Tasmania or an approved inspector.
- Northern Territory (NT) – All plants require a PHC compliant with NT Biosecurity regulations.
❌ PHC NOT Required For:
- Shipping between Queensland, New South Wales, Victoria, South Australia, and ACT (mainland states)
- Sending seeds (different regulations apply)
- Sending cut flowers or foliage (unless to WA)
How to Get a Plant Health Certificate
Obtaining a PHC involves several steps and must be done through official channels. Here’s the process:
- Arrange a Government Inspection
Contact your state’s Department of Agriculture to book an inspector. Inspections are charged by time (typically $37.50 per 15 minutes), with a minimum fee. You’ll need to provide details of the plants, destination, and shipping date. - Prepare Your Plants
Plants must be clean, clearly labelled, and ready for inspection. Remove dead leaves, check for pests, and ensure plants are properly potted. The inspector will examine all plants thoroughly—any sign of pests or disease means failure and re-inspection. - Chemical Treatments Applied
The inspector will apply (or supervise you applying) required chemical treatments. This typically includes broad-spectrum insecticide and fungicide. Treatment costs and chemical costs are additional to inspection fees. - Inspector Issues PHC
If your plants pass inspection and treatment, the inspector issues the official PHC document. This certificate must travel with your shipment—either physically attached to the packaging or electronically lodged (depends on destination state). - Ship Within Validity Period
PHCs are typically valid for 14 days from the date of issue. Your plants must arrive at their destination within this window, or the certificate becomes invalid and the consignment can be rejected.
The Reality: Why DIY PHC is Difficult
While the process sounds straightforward, there are several practical challenges:
- Minimum inspection fees – Even for a single plant, you’ll pay for at least 15-30 minutes of inspector time (~$37.50-$75)
- Inspector availability – Government inspectors work business hours and may take days or weeks to schedule
- Chemical requirements – You need to purchase and correctly apply specific chemicals (which come in large commercial quantities)
- Documentation complexity – Forms, lodgement systems, and compliance requirements vary by state
- Single consignment only – Each PHC covers one shipment to one destination. Shipping to multiple customers means multiple inspections.
For most people, getting a single PHC costs $100-$200 minimum when you factor in inspection fees, chemicals, time, and complexity.

Frequently Asked Questions
Yes, you can arrange your own PHC by contacting your state’s Department of Agriculture and booking an inspector. However, for most small-scale growers or one-off shipments, the cost and complexity make this impractical. You’ll need to pay minimum inspection fees, purchase commercial-quantity chemicals, and navigate state-specific documentation requirements. For occasional shippers, using a service like Paradise Distributors is far more cost-effective.
PHCs are typically valid for 14 days from the date of issue. Your plants must arrive at their destination within this period, or the certificate becomes invalid. This tight timeframe is one reason why coordinating your own PHC can be stressful—delays in shipping or postal disruptions can invalidate your certificate and result in your plants being destroyed at the border.
Yes. Each consignment to a quarantine state requires its own Plant Health Certificate. If you’re shipping to multiple customers in WA, TAS, or NT, each customer’s order needs a separate PHC (unless shipped as a single combined consignment to one destination). This is another reason why batched commercial services are more efficient than individual DIY certificates.
If the inspector finds pests, disease, or other biosecurity risks during inspection, your plants will fail and cannot be issued a PHC. You’ll need to treat the issue (often requiring specific pesticides and waiting periods), then arrange a re-inspection at additional cost. Failed inspections add significant delays and expense, which is why professional pre-inspection preparation is valuable.
No. Under Western Australian biosecurity law, all plant material entering the state must have a valid Plant Health Certificate. Attempting to ship without one will result in your consignment being intercepted at the border, destroyed, and you may face fines. WA takes biosecurity extremely seriously—there are no exceptions or workarounds.
A Plant Health Assurance Certificate (PHAC) is a streamlined certificate available only to businesses accredited under ICA (Interstate Certification Assurance) schemes. To qualify, you need to maintain comprehensive quality assurance systems, undergo regular audits, and pay ongoing accreditation fees. PHACs are faster and cheaper per shipment but require significant upfront investment. For most small growers, standard PHCs arranged through a service provider are more practical.
Seeds have different regulations than live plants. Generally, seeds don’t require a PHC for interstate shipping, but they may require treatment declarations or import permits depending on the species and destination state. Always check specific seed regulations—some species (like citrus or tomato seeds) have additional restrictions.
PHC documentation and treatment is included as part of our quarantine concierge service—there’s no separate PHC fee. Our pricing is based on destination state and service level. Because we batch inspections every 3 weeks and handle multiple customers per inspection, we achieve significant cost efficiencies compared to individual DIY certificates.

The Bottom Line: DIY vs Professional PHC
Getting your own Plant Health Certificate is legally possible, but practically challenging for most plant enthusiasts and small growers:
| Aspect | DIY PHC | Paradise Distributors |
|---|---|---|
| Cost per shipment | $100-$225 | Included in service fee |
| Your time required | 2-4 hours | Zero |
| Chemical purchase | Commercial quantities required | We handle |
| Inspector coordination | You arrange and schedule | We handle |
| State compliance knowledge | You must research | We guarantee |
| Risk of rejection | High (first-time users) | Very low (professional process) |
| Timing stress | High (14-day validity) | Low (we coordinate) |
Our recommendation: Unless you’re shipping plants interstate regularly (multiple times per month) and have the time to become an expert in biosecurity compliance, using a professional quarantine service is faster, cheaper, and far less stressful than DIY Plant Health Certificates.
