I think we can use my 3d printer to print a stencil that we could all paint on shirts or a blindfold.

The blindfolded prisoners demonstrations seem pretty effective.
The more people we have the more intimidating it is for people.
If we are doing a demonstration to educate people it can be small guerilla type actions with a couple people peacefully protesting at various locations wearing similar things. We all find photos and stuff to print out as a team. Then we do it in our local areas and reach out to others.

If we are doing a protest to show people power and to try and motivate government to criticise israel, then we need to show the links between israel and the Aboriginal deaths in custody, make our messaging personal.
This is a racist law.
