UPDATE
So I just got back to Oz. Took the punt and smuggled my entire collection undeclared. All good, we are laughing. I got worried when I was pointed to the customs gate and saw line ups at all the scanners, looked like everyone was getting checked, turns out they were just the honest ones. Officer saw my “nothing to declare” card and pointed to door 8. Felt like Leo DiCaprio in the ending of Inception. Celebrated with a PSP D4 on homecoming which was a brilliant smoke btw el prez. Happy days.
