The video wiki site Ezvid Wiki has listed Sean amongst its list of ’10 Australian Authors Who Write Amazing Science Fiction’. 

“When you hear the words “science fiction,” Australia might not be the first thing that comes to mind. But there are many talented writers from the land down under who explore technology, the future, and the farthest reaches of space with compelling characters and well-written prose. The ten authors listed here have written some great sci-fi that deserves a place on your shelf.”

Listed as notable works are his collections Colours of the Soul and Ghosts of Engines Past. “Though many of the fifteen tales here are brimming with humour, McMullen has written them in such a way that they make the reader think seriously about them too.”
