The Abbott government is pressing ahead with plans to fortify the ministerial wing of Federal Parliament that will see the Prime Minister's office screened by a steel security fence and two bullet proof, concrete gatehouses.

House of Representatives Speaker Bronwyn Bishop is now seeking parliamentary approval for the new "perimeter security enhancements".

The new physical security measures, which according to Mrs Bishop's office will cost around $2 million, follow the highly visible upgrading of Parliament House security after the national counter terrorism alert level was raised last September and the Canadian Parliament was attacked by a gunman in October.

In September, Mrs Bishop and Senate president Stephen Parry established a Parliament House security taskforce including representatives from the Department of the Prime Minister and Cabinet, the Attorney-General's Department, the Australian Security Intelligence Organisation, Australian Federal Police and the Department of Parliamentary Services.
