Here is another picture of my Camellia Sasanqua hedge with browning and dying growth. It is quite prominent at one end in 3 of the plants.
Here is an article that covers questions about Camellia care.
I do suspect this is a fungal issue with your hedge. I would treat the hedge with a fungicide.
I recently planted a fragrant pink camellia. I noticed yesterday that some leaves are curling tightly. What is the cause and remedy for curling leaves? Thank you.
Since this camellia was just recently planted, I suspect that it is not getting the proper nourishment that it needs as it tries to settle in its new home. The best thing you can do is make sure your plant is getting the TLC that is requires. Camellias require frequent watering once planted - you can scale back to once a week once the plant is established. You can also assist the plant with retaining moisture by putting down a generous layer of organic mulch around the base of the plant.

My husband has rescued a large camellia. We have planted it. Will it die if we prune it while it's in bud? It's just a bit too big for the part of our garden we have planted it in!
Ideally, a camellia should be pruned after it has stopped blooming (May-June). No harm will come to the plant if you prune it at other times, but it may remove some of the blossom buds for next year.

My camellia had lots of new leaf buds but NO flower buds. What can cause this, please, and what can I do?
It may be too early to worry. Camellias form flower buds in late summer and autumn, especially on new growth. That being said, I would review the article below, particularly the section "growing camellias" and make sure you are following all the plant requirements with regards to lighting, moisture and feeding.
Can I repair a split at the base of a camellia? The plant is about 18 inches tall and in a small pot. I only just bought it and when I came home noticed that at the base, where the stem divides, there is a 1" split. This is not new. Can I bind it to repair and, if so, what can I apply to the damaged area? Many thanks.
Plant tape or electrical tape will work nicely and is said to be stretchy enough to accommodate for plant growth. You can provide your camellia further support by inserting dowels or craft sticks in the soil by the stem and taping that to the plant to keep it upright, if that is necessary.
Is the wound sealed? I am thinking it might be since you said the split wasn't new. If the split is not sealed, you could dust a little cinnamon on the open plant wound. Cinnamon is a natural fungicide.

I have a mature camellia plant that has grown out of control. I would like to 'top' it and lower its height so that it can thicken out like a hedge to act as a screen.

Appear to have been chewed but no sign of any insects, only lots of spider webs. There are irregular shaped holes in middle and edges of leaf (more predominantly in middle) that start as a brown patch on underside of leaf and progress to a hole right through it. Similar holes in Feijoa leaves in same garden.
The presence of spider webs may indicate the presence of spider mites. You can read more about spider mites and the prescribed course of treatment here:

As for the brown patches on the underside of the leaves that progress into holes, my best guess is that this is some sort of fungi leaf spot fungi. In such cases, the center of the leaf spot will dry up and fall out, giving the leaf a "shot hole" appearance. Can you upload a photo of your camellia leaves? I was wondering if they looked something like this:

Irregular shaped holes in leaves could also be caused by slugs or even caterpillars but that kind of damage is usually not preceded by brown patches on the underside of leaves.
