The Elaeagnus is easily 3.5M, evergreen, and
should be available in Australia. Plant them about 1.5 M apart and they will get thick branches that also form a barrier, in addition to the thorns, and will easily grow from cuttings.
An important distinction: Permaculture is not the same kind of gardening as organic gardening.
Mediterranean climate hugel trenches, fabuluous clay soil high in nutrients, self-watering containers with hugel layers, keyhole composting with low hugel raised beds, thick Back to Eden Wood chips mulch (distinguished from Bark chips), using as many native plants as possible....all drought tolerant.
