Prime Minister Scott Morrison and Opposition Leader Bill Shorten have set April 29 as the date they will meet for a head-to-head debate in Perth, The West Australian reports.
The Labor leader was reportedly planning to spend the week beginning April 29, about midway through the campaign, in the city.
The debate will canvass key election issues such as taxes, health care and jobs.
Calling it a "great opportunity to demonstrate the very clear choice at this election", Mr Morrison told the newspaper.
The Liberals are hoping to hold on to the 11 seats they hold out of WA's 16, and are also eyeing off Cowan, which Labor's Anne Aly holds by a margin of 0.7 per cent.
