14:00 - In one of his most good humoured performances of the campaign, John Howard has announced $100 million for water funding in Tasmania with half of the money to be spent on developing effective rural irrigation systems. 

Industrial relations was raised during the doorstop with Mr Howard saying there are no plans for a re-elected Coalition government to further alter the WorkChoices legislation. Howard again pushed the party spectre of a Rudd Government being pushed around by unions and predicted the return to the ALP of dumped union leader Joe McDonald.

12:00 - The Prime Minister has not wasted his only trip to Tasmania in the election campaign pledging $470 million in funding for the state's roads.

Faced with the prospect of an electoral white wash, John Howard heaped praise on the Liberal candidte for the crucial seat of Bass, Michael Ferguson.

9:00 - John Howard will visit Tasmania for the first during his campaign and is expected to make stops in the key marginal electorates of Bass and Braddon, where the proposed Gunns pulp mill and Mersey Hospital takeover are hot issues.

Howard was reportedly heckled by anti-pulp mill protesters holding placards and shouting "Stop the mill" during his morning walk in Launceston.

The visit comes amidst Labor accusations of an IR cover up by the Coalition, which has won a Freedom of Information battle to keep a confirmed draft of a second wave of industrial reforms secret.

"Those documents were 'advice to Cabinet' documents in relation to the decisions taken in 2005," the PM said.

"Those sort of documents are not normally released because they're part of the Cabinet process - there's nothing conspiratorial about that."

But Julia Gillard was unconvinced. "Why should we believe what comes from this Government about WorkChoices when they didn't tell Australians the truth before the last election," she said.

"If they had nothing to hide then they would be releasing those documents."

Meanwhile, rogue Nationals Senator Barnaby Joyce said this morning that he would vote with a Labor government on its IR roll-back. This means a Labor government would not have to wait until the next intake of senators in July to push their own reforms through.
