SANFL vs the GAA early 1980's

With the match on tonight between the AFL and the GAA it was brought up at work that the SANFL played the GAA also in the early 1980s.
Details are sketchy, yet its believed that it was a composite side that wore the CDFC guernsey and were coached by the Centrals coach and the coach of a local Gaelic side here in SA.
The result was that the SANFL side lost by a long way and the concept was later abandoned.
Just wondering if any of the SANFL history buffs are across it and can fill in any more details?
