Maj, We got Avgas there a couple of years ago. There was a phone number on his little shed to ring the owner, he took our details then gave us the combination for the lock. There was an honesty tin there. As long as nobody has tried to rip him off it should be the same deal.
Goondiwindi has a "so called" card Avgas bowser. At least that is what we found when we tried to get fuel there last year. None of our credit or fuel cards would work with it, so we called the number on the bowser and was told the cards do not work anymore and there was a $100 call out fee!!!!! We were told the cards did not work for quite some time, at $100 a time why would he want to fix it!!!!
