Currently, 18 countries have pre-treatment requirements - the proposed new list will increase to 33 countries.
All imported cargo related to vehicles will need to be treated off-shore, including sea containers. In the past, only uncontainerised cargo has required treatment before arrival.
Ministry for Primary Industries (MPI) also intends to refine some of the off-shore management requirements under the existing import standard for vehicles.
It has also worked with the Australian Department of Agriculture and Water Resources to get measures that are aligned, making it easier for traders and shippers to comply.
MPI has increased its border checks of arriving vessels at the start of this year's stink bug season. It also introduced tighter rules for importing vehicles for several countries.
So far this season, to the end of March, border officers have detected 123 live stink bugs.
The consultation will run from April 3 to June 3.
