Former Labor leader-turned-journalist Mark Latham has confronted Prime Minister Julia Gillard on the campaign trail at Brisbane's Ekka show.

Mr Latham is producing a segment for the Nine Network's 60 Minutes program and asked her why Labor has complained to the network about his presence.

But a smiling Ms Gillard responded that she didn't know anything about it and wished him well with his journalistic endeavours.

The Nine Network has not responded to calls asking to confirm that a complaint has been made.

Mr Latham's appearance with the press pack has caused a stir with curious journalists peppering him with questions during an impromptu media conference on Saturday.

The former Labor leader was reluctant to ask questions, telling them they would have to wait to see his story when it goes to air.

Meanwhile, Julia Gillard says she and her predecessor, Kevin Rudd, will not be campaigning alongside each other before election day.

Ms Gillard said she had spoken with Mr Rudd about his involvement in the campaign during talks in Brisbane today.

"I did have a meeting with Kevin this morning," Ms Gillard told reporters outside a Brisbane aged care centre.

She defended the tight management of journalists leading up to the meeting, saying cameras were allowed into the start of the meeting.

"Kevin and I sat down this morning to talk about his involvement in the campaign," Ms Gillard said. "Kevin and I share a deep set of beliefs, a deep set of beliefs, about the future of this country."

She said she and Mr Rudd would campaign separately to "maximise spread" in a number of seats but refused to say where, citing campaign protocol. She said Mr Rudd would be at the campaignlaunch on August 16.

As to whether they discussed how to handle questions about the government under Rudd having "lost its way" she said no, it was not discussed.

"Kevin and I are very clear about what this election campaign is about . . . Of course, Kevin is rightly proud of a number of things that he did as prime minister and I would expect him, as he did the other day, to continue to talk about some of his great achivements as prime minister and the great achievements of this government."

Ms Gillard became tetchy when questioned as to any physical contact between the two, for example a handshake, saying "reality exists whether you [the media] are there or not".
