Definitely Glass! Fully frameless is the way to go. Visually it disappears allowing you to view your pool area uninterrupted, no posts or prison bar effect. If you can't afford to do the whole lot at least do the the part you directly look at from the house and do the aluminum pool fence on the sides. You don't have to clean a glass fence anymore than you do your windows outside. I have 25 mts of it... Hardly ever touch it. Best is just a soft broom and a hose! It also has the added benefit of being a wind break when you are in the pool. Just make sure it's ASA approved and installed by a reputable company to comply with code.

Breaking up the great solid block of colour a little bit helps to hide it. Next is the choice of what to plant. I'm leaning towards: ficus pumila, climbing fig, which can be pruned to hug the fence tightly, Himalyan blue bamboo, (but might sprout on other side of fence as well, so should have a 60cm deep root guard or be planted in pots) or waterhousia floribunda, weeping lilypilly, which can be pruned to a narrow, non-climbable hedge but 30cm might be about as narrow as possible. I'm just a bit scared the bamboo will move into the neighbours yard too...You also have to be careful to not plant anything with massive roots that could eventually crack your pool, and it has to be tough enough to cope with a bit of chlorine... Then, put in a dip line so you don't have to water such a narrow spot. Good luck, and let us know what you decide.

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.

Last month I installed glass pool fencing, which actually transforms my ordinary pool into a unique and gorgeous paradise and on the recommendation of my brother, I got in contact with the Sloane Accessories, the professional contractor for glass pool fencing, they installed a glass fence around my pool which adds style and elegance to my pool. As Glass fencing is the most elegant and preferred choice among people. This gives an attractive look to pools along with maintaining cleanliness around it. Although a bit expensive as they maintain the beauty of surroundings, with safe and higher durability.
