I wrote an article on packet still being alive for our national AR 
magazine last year and that got published. I haven't tackled APRS yet 
because it's still all too new to me. Whilst I understand the basics, 
there are users in higher APRS density areas who are much better 
informed and skilled than me to write about APRS here in Oz. However, I 
can, and will, publicise the fact that the digi is up and running 
running, once it is.

There have been many attempts over the years to produce repeater guides 
for travellers but they all seem to fall out of date too easily. Adding 
to our problem here was the fact that until a few years ago the WIA 
(Wireless Institute of Australia) was comprised of state divisions, with 
the word division being so very appropriate. Each division thought their 
way of doing things was the best so we ended up with a terrible mess for 
interstate travellers. Even though we now have a truly national 
organisation, some states weren't prepared to transfer their assets to 
the national body and the problems of the first 90 years are being 
perpetuated to some extent.

As an example, 145.175MHz was chosen as the national APRS frequency for 
2m, except for vk3 (and maybe others I don't know about). One can only 
hope that in time all 2m APRS in VK will be on a common channel.
