Hello fellow aussie friends.., I rang up Harris Farm and they told me they do sell them, however the season for it has finished, but they rang around some stores to find it for me and turns out I'm in luck !!! I've asked the manager to set 4 aside for me to pick up tonight....yayyy ! $3.99 kg.

they also go by the name of Marrow.....

Do you ladies have Harris Farm there ?? Good luck, I really hope you have luck finding it. I'm going to make "spaghetti " and meatballs tonight....I'll let you know how it tastes.
