This one looks similar to the jersey worn in the 1973 grand final; I haven't seen any of these for sale, but in the Sharks online store you can buy the 1978 grand final jersey (which looks similar but with the modernised club emblem and v-neck collar), and also the original 1967 jersey.
I emailed the online store to enquire about getting a 1973 Grand Final jersey but they didn't seem to show any interest in making one, which is a pity because I think is the best Sharks jersey.

I think all the retro jerseys are manufactured by Classic Sports, so probably your best bet would be to email them to see if they have one or if they would be interested in making one. On their website http://www.classicsports.com.au/home.htm
they say that the selection of retro jerseys is always changing, and to let them know if you can't find what you're looking for as they may be able to put it into production if there is enough demand. Their email address is sales@classicsports.com.au
