Hi Ronel, I've created the category, I think it's correct according to other Western Cape cemeteries. Actually, that page is meant for requests for Australian categories, but I've added it for you, and I think it's in the correct location structure.
What you did, requesting the new category on G2G, is the correct method, but if you do any more, I would suggest adding the tags "Cemeteries" and "Western_Cape_Province" to your G2G question to get the attention of members more familiar with South Africa locations structure.
