Harvey-Brunswick is correct. Not Bunbury. But the other part about Hughes being drafted from WAFL club Swan Districts is correct. He played WAFL with Swans at the time of drafting and then after being selected by Freo was moved like everyone across to Peel.It seems Hughes is considered a local player due to his original club being within Peel's zone. Not sure which club he was drafted from comes into it at all. Most players don't switch WAFL before being drafted but Hughes did.
The situation with Hughes is similar to a delisted AFL players returning to their original WAFL club. Must apply to players that switch WAFL then switch back too which is sort of what Hughes has done
This matter is slightly more confusing as Harvey is Peel's zone but Bunbury belongs to Swan Districts. I believe the Wikipedia page is wrong and and Hughes is actually from Harvey or somewhere nearby.
