Hi Col.
Dunno if this is the perfect product - but it worked extremely well for me on a brick fence...
Welcome to the Bunnings Workshop community @Col8. It's brilliant to have you join us, and many thanks for your question about repairing a brick fence.
Are the cracks following mortar lines or through the bricks? Is the fence painted? @Noyade has mentioned Lanko 5kg 136 Rapid Patching Mortar, and it's a perfect product for the job. If the crack follows the mortar lines, you might like to chase it out, removing any loose material with a Kango Multi Use Joint Knife. This will open up the crack and allow you room to fill with the patching compound.
If this is an unpainted brick wall and the cracks are through the bricks, then you might like to mix in some oxide to the patching cement to mimic their colour better. Alternatively, we have a range of mortar repair fillers that remain flexible once set. If there is a continuous movement to the wall, these could be a good option as they won't re-crack as a cement-based filler would.
Please let us know if you have any questions.

We do have a render-like paint @Col8. Dulux 10L Texture Full Cover Exterior Paint is a gritty viscous paint that mimics a render finish. It sounds like a good option, especially if the rest of the wall is looking a bit tired.
