Having the same issues sourcing maps and charts.
1. The briefing office at domestic - Sold out.
2. ASL [Tower side of Jacksons] - Sold out. Got put on a distribution list, but that will only cover me for VTCs as they don't have the ONC/TPC or WAC charts
Told to go to.....
3. The National Mapping BUREAU. Result - Sold out!!
Certainly of all the useful on land ONCs... Next print 3 years according to the bloke I spoke to.
Best he could do was suggest someone from the Bendigo Army Barracks was printing copies. Haven't tried following that fruitless lead.
4. Googled a link that took me to the RAAF. Have put in an order, but don't fancy my chances. Bloody frustrating. Have any of the posters had any luck lately on this topic as it has been a while since the last post.
My Co has given me one of the A4 books, but they're pretty clumsy for navigation purposes.
