Sending plant samples to Grow Help Australia

Christmas–New Year closure

We will close from Wednesday 24 December 2025 and reopen on Monday 5 January 2026.

Samples must be received before Friday 12 December 2025 to allow enough time to complete initial testing and send preliminary results before the closure. Final reports will be sent out when possible.

Contact us if you have any questions.

You can submit samples using overnight courier or express post, or by delivering the specimen personally.

Samples without a completed online submission form may be delayed.

When to send

Post samples on Monday, Tuesday or Wednesday, if possible. Samples that sit in transport over weekends can become degraded. Water samples are best sent on Monday or Tuesday.

Before you send

  1. Correctly package your samples.
  2. Complete the online sample submission form.
  3. Print out and include your confirmation email with your samples.
  4. Meet any quarantine laws or requirements.
  5. Address your sample correctly.

How to find us

  1. Enter Boggo Road and turn right onto Joe Baker Street at the end (there's only one way to go and there are significant Cross River Rail construction activities impacting Joe Baker Street).
  2. Drive down to the bottom of Joe Baker Street (there are no street numbers) to the B3 loading bay entrance on the right and drive in.
  3. The loading bay has a roller door with a buzzer to hand over samples.
  4. Ring the buzzer for help if there is no one present when you arrive.
