Project Runway is not screening in New Zealand so sister Hannah Kelly is downloading the show to watch her brother's progress.
She has not been able to speak to her brother since he was selected for the show and says it has been tense, with Sean in lock-down and no communication possible.
"I'm really proud of Sean, he is taking the criticism from the judges on the chin well and some of it is pretty harsh."
Hannah enjoyed watching the show with her brother while they were growing up, and she's hoping it won't be too much longer until she can talk to him.
"New York Fashion week starts in a fortnight over there and I'm hoping we will be allowed to talk him after that.
"It is funny seeing him on the show, I thought his accent would stand out but it doesn't."
