I'm not sure if many people would be able to identify your grass type from a single image. We'd likely need several, including close-ups of the blades. If you could take a few more closer images, we might narrow down what it is. It's certainly not a coarse bladed grass like Buffalo and is more likely something similar to fine or tall Fescue.
Regardless of the type of lawn it is, they all require much the same kind of care. The only time you really need to be careful is with varieties like Buffalo, as they are susceptible to certain selective weed killers. If you use the wrong product on them, you'll potentially kill the whole lawn.

Hi @mazza hard to tell without a close-up of leaf blades but I am going to go for it being a kikuyu hybrid.
