fly fishing online store

I want to say – Which of these is a niche?
What would be considered a niche? Is it "fly fishing" a niche, as it is reduced to "Fishing"? Or is "Fly Fishing in Brisbane, Australia" closer to what the term is it? Or say an online store that sells digital products only (range of products that are delivered digitally) on a subject as vast as the interior design. Is a niche, because it is the sale of certain types of products for major themes? Or the real question was reduced to a small area of interest you? Thank you.
(Y no, I'm not selling the design of digital products for interiors, I)
fly fishermen and women would restrict a niche and be based in Brisbane is a solid niche. A niche market is usually the goal rather than the product you are promoting. His example of interior design products, digital and is not a niche. Niches for the products would be students interior design or who is considered the target market. In our company, we offer marketing courses, as many companies. We are targeting niches such as art galleries, editors and owners of Bed & Breakfast. We also reduce the number of geographic areas specific such as London, Manchester and Glasgow.
