International shipping is now available!   It is expensive to send the larger garden beds via air-freight and Australia is a long way from most places! We have had a lot of interest from the USA and Canada and we will be looking for a local distributor after the COVID situation settles down around 2023. We will then be able to ship container loads which will make the garden beds more affordable, so please register your interest  HERE.

If you have any further questions about our Green Mongrel Garden Beds please CONTACT US HERE.

The pricing in the drop down box excludes any delivery fees, which are added according to your location.  Black and Grey Mist are the same price.  All pricing is in Australian Dollars so that is approx 26% less than USD.

  7. Kyle & Rachel Dunlop

    We have bought 2 of the 72.5cm garden beds earlier this year and planning to buy more for these reasons:
    1) most affordable garden bed for that volume/size
    2) sustainable
    3) utilise the plastics that we recycle and return
    4) tallest beds we can find – prevent back pain, especially since Kyle is 195cm
    5) easy to assemble
    6) easy to disassemble when moving
