Some years ago I did a skills assessment as a plumber, My qualifications are in Gas Engineeing with lots of plumbing experience. To reapply for another skills assessment as the original one expired. I have lots of information on my plumbing background, but now want to inc my gas fitting experience as the skill is now on the list plumbing was only on when I applied previous. Sorry to go on a bit lol .. lots of info but need help in completing the document for the skills assessment to the Australian government departments. I'm currently on my holiday and will be back in the uk 25th June. Please contact me if you would be interested and can help. Scott Green
