Is it safe to use wood (untreated) poles pushed into the gravel in GBs as plant tressils/supports?

Thanks

It should be, no reason why not if they are untreated (or branhces from your own trees - so you can be certain there is nothing in them).

Yes, but it will rot quite quickly compared use in a dirt garden. Bamboo lasts longer than jarrah. If you're using hydroton, even with a depth of 300mm there is not a lot of support for heavy plants, especially in a seabreeze, so you're better off, if you can, making an external trellis by securing posts outside the GB and then using string lines or similar to support the plants in the GB.

B also has some triangular "tomato trellis" systems which have been used to good effect in AP systems; I think Charlie has some pics on his system thread? They're going to be my next purchase. They sit on top of the media instead of being buried into the media.

Good ideas guys , thanks.
