Which diagrams are you looking at? Without knowing your specific submodel I just clicked on two different 250 CDI parts diagrams and they both only show the M7x79. Usually they would list all the options if there were any.

I dont know about shipping to Australia.

Im finding the 7x79 bolts locally from me at IDparts for $1.95/each. They say they ship internationally but not sure how much shipping would be. https://www.idparts.com/injector-hol...VRYhg3bS_H2CKT

I wasnt aware they are one time use bolts until looking just not.

Looking on onlyeuro.com it appears that is the correct bolt for the 250 CDI. Clicking on the other bolt part# the 250 CDI does not show. https://onlyeuro.com.au/products/mer...e6a1673c&_ss=r
