They are the old Benson & Hedges cricket fixture cards for each Australian summer.
They used to come in the Woman's Weekly in Sept/Oct issue each year (Ch 9 and Woman's Weekly both thru Kerry Packer hence the cross promotion).
I have every year from 1991/1992 to present in the various forms. These cards are all about 8 inches long and fold in 3, so you can put them in your wallet. I prefer them flat, but beggar's can't be choosers. They bob up on ebay once in a while, not as often as about 3-4 years ago. I lost a bid that had all of them from 1983/84 to the mid nineties about 18 months ago, and seem to have dried up since.
If anyone has any spare, knows any dealers, has any under the bed, willing to swap or give some coin in return.

For some reason, I couldn't attach the photo examples to the post. Anyway - same as in the avatar.
