Hi Caterpillar, and Welcome.
Best service, and a rapidly growing business with a strong on-line presence is My Slice of Life. They would probably look at importing or sourcing what you require.
I am base on the Gold Coast, they are in Melbourne, but I get my deliveries max 48 hrs, but has been less than 20 hours after the order was placed! I get the majority of my Stock from these Guy's. Well priced
Another Company to try, and these Guys are in Aus and New Zealand, is The Casing Boutique (
www.thecasingboutique.com). They sourced pig bladders for me when I was searching to make my Culatello. More expensive, but quality product. I only buy my casings from them now, and that is all they specialise in, so could be worth investigating.
Smoked and Cured is a recently purchased web based company. they certainly have a variety, but are a bit more expensive. I had a few problems with the previous Owners, who i think ran the business down. My last purchase was from the New Owners, however - tho it appeared to be Australia Post, the delivery was some 2 weeks....
Please let me know ( PM me) if I can be of any assistance.
Regards,
Tony
