Marine Gas fitter in Australia (Melbourne)

[slam.1956]

Hello,

I decided to replace the aging 2 stage gas regulator in my 2010 B34, unfortunately the fittings that go into the boat are not something I can get in Australia and while I was removing the aged rubber hose the French fitting broke in half. I figured it would be easier to simply upgrade the connection into the boat while I was replacing connections. Along the way I managed to twist the copper pipe inside the boat where it goes out into the gas locker so that has to go as well.
All sounds easy enough but i have struggled to find anyone that will do the minor repairs. So, does anyone is Australia specifically around Melbourne know of any Gas fitters that will work on a boat? They must be around, right?

btw I tried at first to get any gas certified plumber to look at it and have met with outright "no" as a response. So anyone with a specific contact or suggestion please let me know.
Thanks, in advance.
