Perhaps, but I understand the system strength issue that caused Queensland solar farms to be curtailed last year are well on the way to being been resolved, and I've never read that Kidston has been curtailed (if it had, GENEX would have been obliged to make an annnouncement to the market to that effect), rather a number of farms in the Townsville area and further south.

Another alternative is that it was simply a day when there was a fair bit of cloud around.
