The spread is the whole story
Vegemite itself is almost free: 5 g carries 38 kJ and nearly 1.3 g of protein. The butter underneath costs seven times more than the Vegemite on top. Scraping instead of spreading, or using a reduced-fat spread, takes 100 to 150 kJ off every slice without changing the taste much.
Wholemeal bread lands within about 20 kJ of white per slice but brings roughly double the fibre, which is the change worth making if you are choosing between them.
