It is dead easy for newsagents to let their local politicians know how the new EFTPOS fee regime will affect their business. Click here for a list of house of representatives members and here for a list of senators. With this information you can easily, call, email or write to your local parliamentarians and get them engaged on this issue. Many newsagents already have. The more individual newsagents who engage the better.
I have emailed my federal, state and council members without a meaningful reply (the only reply was from the state members office acknowledgeing my email and promising to forward it to the addressed MP).
At the very least it shows whether or not these politicans deserve our vote next election, not just for reasons of their agreement or not with this issue but more telling, their lack of interest in even responding to this matter.
