I can't remember too many Poms who have played first grade in Brisbane and made an impact. Tony Marchant, Andy Platt, Neil Holding, Tommy Bishop are about all I can think of off the top of my head but I'm sure there are more.
Nowhere near as many Brisbane based players who went over to England I can remember in 84 I think it was, Leeds alone had 6 from the Brisbane comp play for them. Trevor Patterson, Steve Bleakley, Tony Currie, Gavin Jones, Terry Webb and Wally Fullerton-Smith. I know they all didn't play first team footy
