Marketing doesn't have to, and often is best when it doesn't, follow what makes sense to us armchair marketing consultants. As well, it's an Aussie commercial, so perhaps overly mentioning one's product is one of those marketing nuances we yanks don't understand might be a bad thing with other cultures. Finally, "low budget" look is a specific look big productions sometimes go for in commercials (I'm convinced that trend started with the Snapple ads in the mid to late 90's). The fact that he leaves the obvious fake background scene to the immediate left and we instantly hear him splash into the water implies they were deliberately going for the "low budget" look. In short, unless you are invloved in major marketing, you won't know why certain commercials look ridiculous to us, but still bring in more sales than commercial we armchair marketers think would be better.
