Police officers will be replacing soldiers at border checkpoints as the army withdraws from the operation.
Albury police Superintendent Paul Smith said the number of additional officers would be assessed as needed, with the changes coming at a time when crossing numbers are predicted to grow.
"The military are commencing to withdraw from our checkpoints," he said on Friday.
"Operationally we're putting more police in where required across that footprint.
"We certainly greatly appreciate the ADF support throughout this operation."
He said the resources at the checkpoints, and the way the sites ran, was regularly under review with changes made as needed.
"The changing environment, you'll see our infrastructure at our checkpoints is changing accordingly from cold and wet weather, to hot weather," he said.
"Hopefully we don't have to be here throughout summer, but if we do we'll have plans to cope with that.
"I'm just as hopeful as every other resident that these checkpoints will be gone, and gone as soon as possible."
