Class 6.2 Private Quarantine Facilities for Aquatic Plants


These criteria apply to any premises utilised solely for the performance of post-entry quarantine (PEQ) of aquatic plants. It should be noted that the requirements for those facilities that handle emergent species include a requirement for the quarantine house to be fully insect proof. Facilities which handle only species that grow entirely immersed are not subject to this requirement

Premises location

  1. Premises must generally be located within the metropolitan area of a declared port that has a permanently based DAFF Officer. All applications are subject to approval by the Director of Quarantine and will be considered on their individual merits with consideration being given to the biosecurity risk and serviceability associated with the location of each premises.

Building and storage areas

  1. All quarantine areas where goods subject to quarantine are stored or handled must display a quarantine sign to assist in effectively managing the security of these goods. These signs are to be:
  • secured on a building/s, racks, fences, gates and/or doors and be visible at all times
  • permanently affixed
  • of a professional standard
  • made to state ‘Quarantine Area – Authorised Persons Only, No Entry or Removal of Goods, Penalties Apply, (Quarantine Act 1908)’ (or as directed for specific biosecurity operations)
  • on a yellow background, with black lettering.

    Note: Cardboard and paper signs are not acceptable.

    Signs on external structures must be:

  • a minimum 600 mm x 400 mm with lettering a minimum 25 mm height, and
  • be weatherproof and resistant to the elements.

    Signs within structures must be a minimum 295 mm x 210 mm with lettering a minimum 8 mm height.


  1. The quarantine house must be a separate unit used only for the PEQ of aquatic plants for which approval has been granted whilst it is approved for the introduction of plants. The quarantine house may be adjacent to existing facilities, provided a functional/structural barrier is maintained between each area. The barrier must effectively prevent the flow of air and the possible spread of fungal spores from the quarantine area to plants of a similar species.
  2. The quarantine house must be a substantial, properly constructed structure.
  3. The quarantine house must be of a size commensurate with the proposed quantity of imports to be quarantined at the facility and have a minimum of 10 m¿ of floor space.
  4. The quarantine house must be fully equipped with a concrete floor (or acceptable impervious substitute) that drains to a suitable soil trap which is connected to sewerage or septic tank.
  5. The tanks holding the plants are to be placed inside a tray, the bottom of which is to contain a dilute solution of copper sulphate at a concentration of no less than
    0.02 g/100 L of copper sulphate. Alternative methods for the use of copper sulphate to ensure that the tanks are snail proof will be considered on a case by case basis.
  6. The cladding must be substantial. While rigid material is preferred, film plastics may be used. The minimum requirement for film plastic cladding is a double layer of 250 micron thick poly film. Providing they meet the minimum requirements, plastic films can be approved by DAFF Canberra. Renewal should only be made after an inspection to ascertain that the structure is in good condition and likely to remain intact for at least one year.
  7. All doors and doorways into the quarantine area are to be properly constructed and fitted with appropriate seals on the top, bottom and sides. The doors are to be provided with locks and handles enabling them to be opened and closed from either side. A self-closing fitting is required on either the internal or external door.
  8. Where a facility is deemed to be insecure and adequate repairs cannot be carried out immediately, the plant material present must be ordered to a secure quarantine premises until all repairs have been carried out to the satisfaction of the DAFF Officer.
  9. The aquatic plant-house is to be kept locked at all times except when access by authorised persons is required.
  10. Access to the quarantine house must not be through any other areas where plant material is being grown, i.e. the quarantine house must have its own entrance.

Additional construction requirements for facilities which will house emergent, plant species

  1. The quarantine house must have an insect-proof door entrance porch or 'lock'. The entrance porch or lock must be of sufficient area to permit the entry of people, plants and trolleys into the lock to ensure that only one door may be open at any one time.
  2. The quarantine house must be maintained in an insect proof state. The cladding must be sturdy and affixed in a manner which effectively excludes all insects. All openings (including evaporative cooling systems) in the facility must be covered with permanently fixed gauze with a maximum aperture of 0.5 mm or 500 microns. Whilst metal gauze is preferred, synthetic meshes may be used. Synthetic meshes can be approved by DAFF, provided they retain the minimum aperture dimensions when fixed in place. For this reason welded mesh is preferred to woven mesh types. Where plastic mesh is used, the responsible officer must ensure that the mesh is maintained intact to specification for the duration of approval.

Waste disposal

  1. All biosecurity waste must be disposed of in a manner approved by DAFF.
  2. Sufficient bins/containers (with lids) of an appropriate size labelled ‘Quarantine Waste’ are to be provided for loose items, residues, spillages or material of biosecurity concern. Such bins/containers must have lids that remain closed at all times and are to be emptied and, if required, disinfected in accordance with any provisions set by DAFF.
  3. DAFF approved methods of solid biosecurity waste disposal include incineration at a high temperature in a high efficiency EPA approved incineration facility, deep burial, or sterilisation by autoclaving. Minimum autoclaving times after attainment of temperature for all goods, residues or biosecurity waste shall be:
  • 121°C (core temperature) for 15 minutes, or
  • 121°C for 30 minutes where core temperature is not measured.
Where the 15 minute autoclaving time is used, the premises holder must specify how the core temperature has been reached and detail how this temperature was recorded.

Office and record requirements

  1. Records are to be made available, within a reasonable time, for inspection by DAFF Officers. In addition, these records must be retained at these premises for a minimum period of 18 months during which time they will, upon request, be made available to a DAFF Officer.
  2. A register must be maintained recording incoming and outgoing plants, plant deaths and inspection dates.
  3. Records for each consignment of goods subject to quarantine must include:
  • quarantine direction
  • Import Permit number (if applicable)
  • description of the goods subject to quarantine (including scientific names and quantities, if applicable)
  • date of receipt of goods and country of origin
  • details of any treatments
  • method and date of disposal/destruction of goods subject to quarantine and/or biosecurity waste
  • the date of movement and the DAFF permission for any movement of goods subject to quarantine
  • comprehensive details of any breaches of goods subject to quarantine from the facility.


  1. It is the responsibility of the Applicant to ensure that the premises and all operations comply with all local, state and federal regulations and the relevant state EPA requirements. Documented evidence of compliance with these requirements must be produced to DAFF upon request.
  2. Premises must be securely locked when unattended and after hour access to the premises must be limited to authorised persons only.
  3. Control and security of the quarantine area is the responsibility of the nominated senior person of the company. The name, designation/position title and contact details of the nominated person must be supplied with the application and at each renewal.
  4. All DAFF instructions and relevant DAFF Import Permit conditions must be complied with. Where goods are handled for a third party, it is a requirement of approval that establishment operators have an arrangement in place that ensures they are aware of any relevant permit conditions. Please note that a breach of this clause may lead to suspension of the approval as a QAP.
  5. All applications are to be accompanied by scale drawings of the proposed area and all biosecurity storage, treatment/processing facilities including parking for DAFF Officers. In the case of new constructions these plans must be approved before any construction is undertaken.
  6. DAFF is to be notified in writing at least 15 days prior to changes in ownership, senior management, operating procedures/arrangements relating to goods subject to quarantine or where modifications to those parts of the premises where goods subject to quarantine are stored or treated are planned.
