Yes, I had a look at a couple of books that I had here. The Bathurst '85 and Raceyear '85 books had brief summaries of the late 84/early 85 races.
The Benson & Hedges series as previously mentioned was held in late October/early November 1985.
So, here is a summary of those races.

Now, my memory must be faulty. I thought a Commodore finished second in the first two races and I thought that was the Hulme/Smith car. However, the Bathurst '85 confirms that the Hulme/Smith Commodore had a poor series with an untraceable fuel fault, so it can't have finished.
Now a couple of other notes. I thought the Nissan was driven by Leonard/Sprague, but I read an article in NZ Classic Driver recently profiling NZ saloon car racer Rod Collingwood which mentioned his involvement with the car. Not sure if Rod drove it at Manfield or in some of the NZ Touring Car Championship rounds however. I'll try to find and re-read the article.
Also, I need to confirm with those more knowledgeable than myself or those with access to contemporary reports that I have the finishing order correct.
