Australia’s most prominent anti-gambling advocate Tim Costello is disappointed Prime Minister Anthony Albanese has not announced a betting crackdown before the Dunkley byelection to honour the legacy of the seat’s former MP, Peta Murphy.

The prime minister, who said he has met with Costello on the issue, this week declined to commit to the full, phased-in ban recommended in Murphy’s landmark report handed down in July last year. Governments typically respond to parliamentary inquiries within six months but the Albanese government has not yet done so.
