I have a problem where I see patches of yellow/white when I mow my lawn but is otherwise green when the grass height is high. I cannot seem to figure out the issue. Could it be due to fertiliser burn? Or do I need to aerate more. Pictures attached.
As I mentioned, these only appear after I mow the lawn.

This is a pretty common look to a lawn that has been cut short. With regular cutting at this same length, the yellow spots will clear up. The yellow areas are formed when the grass grows out in length, and the lower areas stop receiving sunlight. For instance, if you let your lawn grow for several weeks in summer and then cut it, the entire lawn will be yellow.
When was the last time you fertilised, and what is your watering regime like?
Let me also mention one of our knowledgeable horticulturists, @Adam_W, to see if he can give us his opinion.
To answer your questions, I last fertilised about 7 months ago and very recently, a week ago. I water twice a week with enough water to all parts of the lawn.
Not the most regular in lawn mowing but here is my plan for my thick blade buffalo grass:
Is that a good plan for autumn or should I wait until spring to do this?
Hopefully @Adam_W has some opinion. Can produce more photos.
And I also managed to find this thread where there is some good advice too.
I have Kikuyu grass in my lawn and also have similar problems. Is it the same solution for this type of grass? I water 2-3 times a week and mow once in 10 days.
Your plan sounds like a good option. You might also want to de-thatch your lawn by taking a rake and removing any dead grass. I believe you'll find mowing at the lowest level a bit of an issue for Buffalo, as that doesn't leave much of the leaf material. I suggest that frequent mowings at the third from the lowest setting would be a better option. Early Spring is always a great time to prep your lawn for summer. You'll find seed germinates much more rapidly then.
