Next in Australia’s review list: international gambling sites.

After announcing last week its plans to review online betting laws, the Australian government now wants to examine all online wagering operators in the country.

Social Services Minister Scott Morrison made the announcement on Monday, media outlet News.com.au reported. Morrison said former New South Wales premier Barry O’Farrell will lead the probe.

Currently, there are 30 online gambling sites in the country, but Morrison said only about 40 percent of the industry’s $1.6 billion revenue enters Australia’s coffers. The rest, according to the minister, goes to more than 2,000 international websites that are out of the government’s reach.
