POLICE will hold another community meeting in Derrinallum on Wednesday night as the mammoth clean up from the bomb blast on the fringes of the town continues.
A one-kilometre exclusion zone is still in place around the Hamilton Highway farm, about three kilometres west of the town centre, following the blast on April 11 which levelled a farm house and large shed.
Two police officers were seriously injured and a local man Glenn Sanders died in the blast, which followed a seven hour standoff after police tried to arrest Mr Sanders for an earlier incident.
Specialist team are still on site combing for evidence, including detonators and more explosive devices. A police command centre is still running around the block and 24-hour road blocks continue.
A police media spokeswoman said the meeting would update residents about the progress being made in the extensive clean up operation which is now in its third week with the bill expected to be in the millions of dollars.
"The meeting is simply about keeping the lines of communication open with the community," the spokeswoman said.
The Hamilton Highway remains closed between the intersections with the Camperdown-Lismore Road at Lismore and the Darlington Road, at Darlington.
The Derrinallum township remains accessible to local traffic.
The police media spokeswoman said it was unclear when the highway would be open again.
"It's a fairly volatile environment and the highway will remain closed until such time as it's deemed safe to re-open," the spokeswoman said.
Police have also asked anyone who has any information about Mr Sanders or any information about items concealed on his property to contact Crimestoppers.
