Our traditions were imported, 99% from Europe. Along with our livestock, crops, & feral pests.
In my mind, the most traditional Aussie knife would be a rabbit skinner kit. Rabbits were a serious feral plague animal in Australia in the first half of the 20th century. Plagues lasted into the 60,s & were controlled eventually by release of the myxoma virus in the late 50's.
A rabbiter's kit, as I saw numerous times in my childhood, was a FB trade style knife, ~5 inch blade, wooden or leather handle, sheathed together with a handless steel. Most were made in Sheffield or Solingen. Gregsteel may have made some, an Australian manufacturer, now defunct.
These are currently made Sheffield knives. J. Nowill brand.
Despite the barlow style folder being named a "bunny knife," I don't think folders were much used for rabbiting.
The excess of rabbit skins lead to a secondary industry that still survives: Akubra

Rabbit fur was made into felt hats.
