Same situation when I arrived at Swampy on 30th December; fortunately, I could go through the Thai lanes with my missus.
We had a long wait for baggage after quickly passing through Immigration. I realised that the carousel could not cope with 500+ passengers arriving on an A380 - especially when most of them were stuck in long Immigration queues. The baggage backed up and cases were 3 deep on the carousel when we left.
