Malcolm Turnbull has summed up the theme of the coalition's campaign launch as a choice between two futures - stability or chaos.
The prime minister on Sunday will be joined by former Liberal leaders John Howard and Tony Abbott at the launch in the inner-western Sydney seat of Reid.
The launch follows Labor's set-piece event last Sunday in the western Sydney Liberal-held seat of Lindsay.
Mr Turnbull said the coalition's launch would sum up "the critical choice that Australians face".
"On the one hand, a stable government which I lead, which has a clear economic plan for stronger economic growth and more jobs," he told reporters in Cairns on Wednesday.

"What we have on the other hand is the potential chaos of a Labor-Greens alliance."
Mr Shorten, who was campaigning in Reid on Wednesday, told reporters he wanted Mr Turnbull to explain why he believed a $50 billion corporate tax cut was a good idea and why he opposed a banks royal commission.
"Malcolm Turnbull has got bad policies before the launch - I suspect he will still have the same bad policies after the launch," Mr Shorten said.
The Sydney venue will be a departure from the past four coalition election campaign launches which have been held in Brisbane.
