Fuel tank clean/repair SE QLD

[grantsmells]

Gday, after having a peek inside my 82 sc fuel tank and reading a bunch of threads about cleaning a tank with the swirl pot, I’m wondering if there’s anywhere I can take a fuel tank to be cut open and cleaned/coated, preferably Gold Coast/Brisbane?
The overall condition inside is quite good except for some pitting on the outlet and return lines. I’m tempted just to leave it as they’ll always be sitting in fuel so unlikely to rust any more, but looking at getting some quotes nonetheless.
