The Aussie defender featured in the friendly win at Gateshead this week.
Good told the Evening Chronicle: "I watched the Premier League all of the time.
"So to be here as a Newcastle player in the black and white stripes - it is surreal almost.
"Me and my mates watched it all the time back home. It is an unbelievable feeling to be here.
"It has dragged on for a while but it has happened. It's about hard work now."
