Labor leader Bill Shorten has admitted Malcolm Turnbull’s son urging voters to dump conservative Liberals in Victoria took him by surprise.

Alex Turnbull has teamed up with left-wing activist group GetUp! to record robocalls calling for the Liberals to be abandoned in key seats.

The targets include Health Minister Greg Hunt, a key backer of Peter Dutton, and conservative MP Kevin Andrews.

Mr Shorten said he didn’t see the intervention coming, but couldn’t resist a dig over last year’s brutal leadership spill.

“Mind you, I don’t think his dad saw ScoMo coming,” he told 2Day FM on Thursday.

Later, Prime Minister Scott Morrison said the surprise intervention would not distract him from the final days of campaigning.

“They are going into the electorate of Flinders where Greg Hunt has served as that member for many years,” he told the National Press Club in Canberra.

“He’s served his community well and tirelessly.”

Also on Thursday, Mr Shorten faced further questions about Alex Turnbull outside a dumpling restaurant in the Sydney suburb of Burwood.

“This government has run out of ideas. It’s rapidly running out of time,” he said.

He said there was a mood for change, listing a lack of climate change action – one of Alex Turnbull’s key gripes – among his reasons.

After a pair of FM radio interviews, the Opposition Leader campaigned in the Liberal-held seat of Reid, helping make dumplings.

Both leaders targeted the electorate, which has a large Chinese population, two days from election day.

Popular MP Craig Laundy’s retirement has made it a tight race despite a 4.7 per cent margin.

One Chinese-Australian voter said many in his community were concerned about Labor’s changes to negative gearing and capital gains tax.

But he’s still voting Labor, annoyed with Mr Morrison describing China as a customer.

Mr Shorten was in a festive mood as he faced light-hearted questioning about whether he’d been to Dan Murphy’s to stock up for election night.

He revealed he plays the discount liquor chain off against rival First Choice, capitalising on price-matching policies..

“This is a little, if you like, a shopper’s hack and potentially a very useful thing,” he told KIIS FM Melbourne.

“See, I’m not just another pretty face am I?”

Later, Mr Shorten will make the case for change in his final major address of the election campaign.

The Labor leader will give the speech at Blacktown’s Bowman Hall in Sydney’s west, where Gough Whitlam delivered his ‘It’s Time’ address at the start of the 1972 election campaign.

The key theme for the speech is “vote for change”, with the address not expected to heavily hark back to Mr Whitlam.

Mr Shorten will argue “the door stands ajar” for a new generation making a major choice about the country’s future.

Climate change will be a major feature of the speech.

Mr Shorten will also warn of the risks posed by a coalition of chaos – a Morrison-Palmer-Hanson minority government.

He will urge Australians to vote for a united and stable alternative with a vision for the future.
