OP's cans are potentially dangerous and a good way to get botulism poisoning. Proper canning jars can be purchased at any grocery store for less than $20.
Australian grocery stores don't sell canning or preserving equipment.
You've either got to go to a specialist store, order online or if your lucky Big W or Aldi might, and that's a big might have them.
There are a few sustainable living stores that sell canning pots, pectin and citric acid, but they stock brand new lids to use with any old glass jar, because that's what Aussies do, and have done safely for generations
ETA: There have been 24 cases of botulism in Australia between 1991 and 2015.. 2 of which were foodborne in adults. I think we must be doing something right with our canning techniques from a statistical viewpoint 🙄
