[4] Dropping out of high school at 16, Quigley became a stockman at Mardathuna Station near Carnarvon before returning to Perth to work as a truck driver for Brambles.
[4] He planned to melt down his life membership badge, have it made into a tiepin with the words Veritas Vincit— "Truth Conquers", the motto of the school he attended—and present it to Mallard.
[7] In 2011, he was accused of bringing the legal profession into disrepute, a charge stemming from his campaign to expose the wrongful jailing of Andrew Mallard for murder, to which he replied "...if you take on corrupt police you will be pursued and they will try and destroy you.
"[8] In November 2011 Quigley was fined $3000 by the State Administrative Tribunal for professional misconduct, again in relation to his successful campaign against police in the Mallard case.
[9] As Minister for Electoral Affairs since the 2021 election, Quigley has been overseeing potential reforms to the voting system for the Western Australian Legislative Council.
