Computing with the Amstrad (CWTA) was published initially in Australia by Strategy Software in Blackmans Bay, Tasmania (this had nothing to do with Strategy Publications in Victoria that produced The Amstrad User - what is interesting is that Strategy Software used to be in Glen Waverley, Victoria next door to Mount Waverley, Victoria where The Amstrad User was produced), and later by Planet Publications Pty Ltd (still in Blackmans Bay, TAS) with the first issue coming out in August 1986 at $3.60 per issue. This magazine was available in Australia, New Zealand, across the South Pacific and even South Africa.
This magazine was essentially an exact clone of the British version of Computing with the Amstrad, except for some program listings, advertisements, suppliers and pricing - this was all local. Agreements were setup with Database Publications in the UK in order to reproduce all of the content. Even the British covers were used - although usually a few months later.
In June 1987 the British version became known as Computing with the Amstrad CPC (as there was a magazine produced called Computing with the Amstrad PCW - also by Database Publications). The Australian version didn't follow suit and remained as CWTA.
What was interesting is that you could actually still get the British version of CWTA across Australia and New Zealand (Alongside The Amstrad User, Amstrad Action & Amstrad Computer User etc)
Like the British version, later issues incorporated Amtix. December 1987 was the last issue produced (even though the original British one continued until it became CPC Computing in September 1988 and was eventually rolled into Amstrad Computer User in January 1989). Throughout production, the Australian version used the older style British CWTA logo (pre-Oct 1986). There is a news article from The Amstrad User that reports the ending of this magazine Here.
