For Labor supporters, Bill Shorten's Budget Reply is the key event of Budget week. But this year, Budget week has extra significance.
When the Treasurer delivers his speech on Tuesday night, he'll be setting out the shape of the government's re-election campaign. It's an unusual circumstance - the government has chosen to use this annual set-piece as a pre-launch soap box.
It's their mistake, because it gives progressives like us a chance to stare down their unfair agenda.
On Thursday night, the public galleries will be abuzz with support for Bill.
Let's commit to also scrutinise the Treasurer's speech on Tuesday night and make sure the vibe is not so lively.
WHERE: Parliament House, House of Representatives
WHEN: Tuesday 3 May, 2016 at 7.00pm
