Protesters have blockaded a weapons manufacturer at their factory in Tennyson, Brisbane.

The protests were sparked by an investigation that revealed Electro-Optic Systems was illegally shipping weapons systems to the United Arab of Emirates at the height of the war on Yemen.

"We are here to remind EOS staff that their employer is a weapons dealer that sells to UAE, Indonesia and Saudi Arabia." said protester Margaret Pestorius. 

"People don't realise there are weapons factories in our suburbs, profiting directly from human rights abuses overseas. EOS is exporting to Indonesia at a time of increasing military violence in Papuan lands, and West Papuan people are dying," Ms Pestorius continued. 

"The current government is giving $30 billion a year to foreign corporations to develop a weapons export industry. This money bolsters human rights abusers like the Indonesian military who have killed five villagers in West Papua since the beginning of the year," said Ms Pestorius.
