Saw that there wasn't an existing thread for this, so made a new one that can be used into the future. Anyway just a few corrections for the DECS (SA) lists.
1602 is based at Heathfield, not Ceduna as listed (I see it twice a day)
1581 is at Heathfield as well; at the moment it is not listed as being anywhere.
1428 is not, and was not at Oakbank (at least not for the last 10 years). It was at Heathfield, and has been replaced with 1602 this year.
1367 has been removed AFAIK. It was based at Mt Barker Primary, but has been replaced with a new Hundai (can't remember which one ATM).
Units that have been auctioned off and therefore removed (from Jan/Feb Obs thread, by "TT")
