With parliament still on winter break, last week's most explosive revelations in Canberra came from the Senate committee examining the government's proposed gambling reforms.

In the kind of move that Labor once derided in their opponents, the government used the cover of the federal budget – while most journalists were literally locked up – to deliver its response to the late Peta Murphy's report into online gambling, 'You Win Some, You Lose More'.

Prime Minister Anthony Albanese finally announced some gambling advertising reform this week, tucked into the end of a speech to the National Press Club with a principal focus on Australia's response to the fallout from the war in Iran, the day after he appeared on national television networks telling Australians not to panic.

The eyes of Australia turn this week to the electorate of Dunkley in Victoria, historically the site of the Frankston riot and just down the road from where Harold Holt disappeared. Now it's the location of an all important federal by-election.

A parliamentary committee led by federal Labor MP Peta Murphy has recommended strong action against gambling advertising, throwing new light on the pernicious relationship of gambling to Australians and Australian politics.
