The Fairfax/Ipsos poll indicates the prospect of a hung parliament has increased as voters flock to third parties.
In two-party preferred terms, it shows Labor is ahead at 51-49 but voters continue to predict a coalition victory.
Opposition Leader Bill Shorten has played down the latest polling that shows Labor trailing the coalition in key seats, saying Labor's issues are "beginning to bite".
He's vowed to keep pressing Labor's position on universities, health, negative gearing and the N-B-N for the final two weeks of the campaign.
"This is a close election. All federal elections are close and this one is no exception. This is probably closer than most," Prime Minister Malcolm Turnbull said.
