horizontal anything is a no, the gap would have to be so small it might as well be solid. yes the vertical cable might pass but you are not allowed to be able to squeeze them together as then the gap distance is non complying, The safest one is the solid section PCA pool fence, or glass, or solid, to 1200 mm in Queensland, no greater than 100 mm off ground, and gaps not able to be manipulated, and to stop that you have to have horizontal section in the cable type, which then do not comply, cut metal screens if complying is OK. I would question the void, and if you know the reason for the void, than solutions will be able to be worked out, now we are asking why? Pools in adjoining yards are acceptable with pool fencing complying on both sides, no void is required. so the void sound a bit iffy, unless it is something to do with storm water, or a building requirement, so ask the question why. Pool fencing can be awesome.

Hi Jenny, I'd suggest popping into your local nursery (not big box store). Often they will offer a consultation service where they can come out and help suggest plants that suit your aspect, climate and situation. The other option is to have a consultation with a local landscape designer or horticulturalist who specialises in planting. Check your local landscape association or AILDM for listings in your area. An outlay now could save you $$$'s in the longer term, as well as making sure that what you do spend your money on is going to give you the most bang for your buck. They'll also have local knowledge as to what can potentially become weeds. Just remember you can't plant anything against the fence that can be considered climbable - this can include hedges. Have a look at the link I included above as to what the definition of climbable is. Look for lush and green to link in with the background. Some pops of colour; maybe foliage (eg alternanthera) or flower (bougainvillea or mandevilla) will also help to lift it and make the green more green. Small growing varieties of lomandra may be better than the large one you have there - this could easily be moved, divided and used elsewhere.

Brilliant thankyou oklouise. I have had success with cuttings before but was hoping to leave the tree in this garden, and I am not sure I can straighten the trunk without moving it further out of the garden bed, or having lower branches too close to the pool fence. I was thinking my only option if I want it in that location is to have a leaning base and attempt to prune to make the top look straighter. I haven't been able to find info as to whether you can have an angled lower trunk and get the top to straighten up, but I like your suggestion of using keywords "pruning to encourage lower branches", I'll give that a try.

Are you installing the spa on the deck or built into the deck? Is your deck structure strong enough for a filled spa with people in it, to be on the structure. This article may be helpful. It states that a permit must be approved for barrier installation. Therefore if you need that permit then your questions regarding pergola posts will be answered by the professional installer. https://www.spaworld.com.au/learn/articles/spa-pool-regulations-victoria-rules-recommendations-more/
