Martin was a short-lived figure in the Australian far right. Hailing from England, the Melbourne based activist was the first to form the Australian Defence League, the Aussie chapter of the far right English Defence League.
Brennen & his ADL buddies organised a rally against immigration in 2011 in Melbourne’s Federation Square, which was met with resistance. Another ADL rally was held in Sydney’s Martin Place.
The same year, ironically enough, Brennan was detained for overstaying his visa and sent to Maribyrnong detention centre and then deported back to England where he belongs. So yea, see ya mate.
