Thank you for pointing this out, Leachy.
I'd like to also combine leachy's post to someone such as Matty's when the term "they're pretty quick" is used as this only ends with us loading the trucks on time. From there, it is all Aus Post. We, Bulk Nutrients, don't actually do our own deliveries. The discrepancies in different arrival times all depends on our postal system.
So with all going well, relying on Aus Posts claimed delivery times, anything under 3kg should be next day delivery. Anything over that weight is up to 5 days. As you can see, there is a post in this thread that says 12 days!
When we hear of arrival times like this, we let Aus Post know about it!
So the answer to this question is anywhere from LESS than 24 hours to 5 working days.
Here is a much larger and detailed answer to this question on our website:

If you have any further questions, just let us know and we'll be happy to answer.
Thank you,
Bulk Nutrients.
