The Department of Home Affairs has suggested using face scans to confirm people's age before they watch online pornography and to restrict access to gambling sites.
The department has suggested checking ages by matching a person's photo with a document already logged with Home Affairs, such as a driver's licence.
"This could assist in age verification, for example by preventing a minor from using their parent's driver licence to circumvent age verification controls," it wrote to a parliamentary inquiry into age verification for online wagering and online pornography.
The United Kingdom this month abandoned plans to introduce a nationwide age verification system for online pornography, after years of technical troubles and concerns from privacy campaigners.
Closer to home, the Home Affairs proposal would piggyback off a separateáproposed facial recognition schemeábeing pursued by the federal government.
The government had floated a contentious plan to permit government agencies, telecom companies and banks to use facial recognition technology connected to a 'hub'.
Under the laws, driver's licence, passport and visa images would be stored by the Home Affairs Department in an "interoperability hub".
However, a bipartisan committee last week told the Morrison government to redraft the proposed laws allowing for the technology's use in Australia, with Liberal and Labor MPs demanding additional safeguards be added.
Sex industry lobby group Eros Association suggested stronger parental controls be made available by internet service providers, pointing to Telstra allowing a filter of websites.
In the association's submission, general manager Rachel Payne says the UK model posed serious privacy concerns and risked creating a potential "honey pot" for hackers.
The University of New South Wales' Law Society said in countries where age verification for porn was enforced, effectiveness was limited with over four million domains and internet tools allowing users to circumvent controls.
But the society did say Italy, Denmark and Spain had successful government-run age verification schemes for online gambling.
The society said the UK's scheme was unable to guarantee the anonymity of users and would have potentially forced them to use multiple third-party age verification systems.
South Eastern Centre Against Sexual Assault and Family Violence said restricting children's access to porn would allow them to learn about sex more appropriately.
