Mr Morrison travelled to the NSW Central Coast seat of Robertson on Saturday to campaign with Liberal MP Lucy Wicks, touring a local fishing shop.

But media were informed during the trip from Sydney Mr Morrison would not be answering journalists' questions, as the federal government faces pressure over a contentious deal between China and the Solomon Islands, and fresh revelations over Liberal candidate for Warringah Katherine Deves.

Mr Morrison was in west Gosford to announce $20 million towards a recreational fishing and campaign facilities program, which the Coalition said would deliver 50 projects in the region. The announcement was an extension of a program unveiled before the 2019 campaign.

The Prime Minister did not answer when asked whether the announcement was pork-barrelling as he left the event.

Finance Minister Simon Birmingham instead acted as the campaign spokesman and took questions from journalists.

The Coalition has been hit with fresh revelations over Ms Deves, who barred media from a campaign event on Friday evening.

It came despite Mr Morrison claiming Ms Deves was being "silenced" and "cancelled", as she faced criticism over a number of comments relating to trans people.

On Saturday, News Corp revealed Ms Deves referred to a leading gay newspaper as "the Rainbow Reich" - an apparent reference to Nazi Germany.

It was previously revealed she had compared anti-trans activism to the fight against Nazis, and claimed a large number of trans women were sex offenders.

She has apologised for many of the comments. Speaking later at a campaign rally in Dobell, Mr Morrison told party loyalists to "vote Liberal, get lucky".

The Prime Minister accused opposition leader Anthony Albanese of running a small-target campaign, despite framing Labor as the party of "big ideas".

"What he has done over the last three years is tell you nothing. He's not about big ideas, he's about no ideas," he said.

Up in the Queensland Liberal-held seat of Forde, Labor was in its second day of campaigning without opposition leader Anthony Albanese, who is recovering from COVID-19.

Deputy Labor leader Richard Marles, shadow treasurer Jim Chalmers and shadow finance minister Katy Gallagher stepped up at Munster Mechanical to campaign on their policy which provides free TAFE for people studying in an area of skill shortages.

An increase to foreign aid was hinted as a possible future policy as Mr Chalmers criticised the government for cutting foreign aid as it has been a "common view across the national security establishment that that has been detrimental to our interests".

However, Mr Chalmers refused to budge on giving a number on the amount of spending Labor would put to foreign aid.

"We will have a policy on the Pacific and we will say more about it during the course of this election campaign. Foreign aid is part of the story, but it's not the whole story," he said.

Further to this, Labor's engagement with China was brought into question again. Mr Marles was asked why he showed a speech given to Beijing University to the Chinese Embassy first back in 2019.

Mr Marles asserted he made a speech criticising China on "their handling of Hong Kong" and their "human rights record with the Uighurs".

"Now how many government ministers have gone to China and in China, publicly criticised the Chinese government?" he said.
