The zipper from my wetsuit went off, so I was wondering if there is some clever tool to get it back in, or some repair shop in Melbourne?
It is an O'Neill one, warranty expired.
Btw what's the deal with wetsuit zippers generally, they work great for 1-2 years, but then they start to stuff up and somehow it becomes impossible to close the frikin zipper yourself.
For the record I'm not 95yo and reasonably flexible 
try a little loven maintenance on ur zip, wash in warm water, get the salt out, maybe some silicone spray, pull it up and down a times till it flows nice
