When I was looking for one to seal mylar, I only found them in the states, so you will need a step down transformer to run one. Same goes for mylar bags, can't use them without a snorkle vacuum sealer or at least that was the case.
I have found a youtube video https://www.youtube.com/watch?v=r9dzaeC0hG0 that shows how you vacuum seal mylar bags with a normal vacuum sealer. May not work for your model or you may need to adapt the technique but it outlines what you need to do to vacuum and seal mylar.
Mylar bags I haven't as yet found in Australia, except this mob that drop ships them. http://www.fishpond.com.au/c/Health/q/M ... od+Storage You can get the on ebay and amazon but postage is the killer, I usually add them to a business order. http://www.agribags.com/Mylar_Bags.html . http://www.discountmylarbags.com/categories/Mylar-Bags/
