After reading the whole thread again you sound like you've realised what a big job you've taken on and how hard it is going to be to repair. OK, so what if you don't do anything for the next 5 years, it will always be waiting for your circumstances to change and your skill levels to improve. Doesn't help that it's at the other end of the country.

One day you'll have room in Melbourne to park it then all your mates will hassle you more so you'll just have to get them involved. You'll be surprised how much enthusiasm you get when there's like minded people around you to help.

Cheers
