South Australia, Western Australia and Northern Territories codes should be AUS-SA, AUS-WA, and AUS-NT. The reason they had three letter codes before the AUS- was added was as WA and NT clash (and SA was given a third letter to not look odd).
The state/territory codes can be used in csvs, rather than spelling out (cf the multi-state USA systems).
The following routes are connected to each other:
ausqld.m001,ausnsw.m001bal
ausnsw.a001she,ausvic.a001
ausvic.a001war,aussa.a001mtg
ausnt.n001,ausqld.n001
auswa.n001,ausnt.n001bul
PS: I can fix these if wanted to.
PPS: the WA part of N1 is missing the SA border point - just something I noticed during my quick look over, eating dinner.
PPPS: I don't know whether it's the looking at Australia, or the tinnie (of the brand that Australians don't drink, but ship over to blighty for the poms), or both, but I've got the
Round the Twist theme stuck in my head. If only it was Nathan Lyon's
off stump flying out.
