besides the one already offered up by Todd, Acacia is probably the thorniest on the planet. I know it is used to deter Lions in Africa, was most likely the plant the Nazarene wore on his head at Golgotha.
If your local Autumn Olive trees have thorns, that would be good choice. Osage Orange is well known in the USA as a great Hedge tree.

the osage is a good choice, the "fruit" has properties that repel bugs, not edible.
Hawthorne and honeylocust are other options to consider.
Elaeagnus Silverberry has big thorns, is fire resistant, drought tolerant and is a thick, dense barrier for privacy. I haven't watered mine in years, but I do keep them trimmed, and the leaves make great compost.
Ghankyou so much for all you fast responses.
Osage is deciduous, Itgorney acacia is a banned weed, honey locust is deciduous, olives mentioned are also a weed here in Western Australia.
So, really I'm looking for;
- height to at least 3.5m
- available in Western Australia
- fire retardant
- drought tolerant
- fast growinggy
- easily propergstable from cuttings
Does such a plant exist...?
Thank you again I hope to contribute some to these forums as well if I can

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.
Just wanted to say Thankyou again for the helpful suggestions. We are going to get some Coral Trees and hedge them. They're super spiny. Semi deciduous, so we'll plant a second row In front to make a heavier blockout.
