Domestic Australian flights could soon face similar security restrictions to international services in the wake of an alleged terrorist plot to plant a bomb onto an Etihad flight from Sydney to Abu Dhabi.
Stricter identity checks are said to be a central part of the security clampdown, which would see travellers required to show photo ID before boarding their flight.
Liquids, aerosols and gels (LAGs) in carry-on luggage for flights within Australia could also face the same limits as for flights overseas.
Also under consideration: allowing only people holding a valid boarding pass past the security gates at domestic airport terminals.
"Aviation security settings are constantly monitored and evaluated by experts in the field who provide advice to the government," federal transport minister Darren Chester told media over the weekend.
"Security measures are kept under constant review to ensure they remain effective and proportionate to the Australian security environment and respond to new and emerging threats.”
