"At this stage we are ahead of the numbers we expected," Mr Facey said at Warrnambool's early voting centre on Monday.

"We have had plenty of people through the door."

There were 15,310 early votes cast in Wannon as of Saturday, about 10,000 more than last week, while the electorate's voters have also applied to make 7747 postal votes.

The number of early votes cast follows a national upwards trend with 2.2 million people casting early votes as of Saturday, one million more than at the same time during the 2016 federal election campaign.

Early voting centres in Warrnambool and Colac have been open since April 29, and centres opened at Portland, Hamilton and Ararat on Saturday, boosting numbers by a further 2330 votes in a single day.

"They all took steady amounts of votes and they are all operating until Friday. Then on the Saturday we open up our ordinary polling places," Mr Facey said.

Five teams of electoral officers also are visiting Wannon's nursing homes and hospitals to collect early votes, but facilities need to house at least 10 voters to be eligible.

The high number of early polls has led to the AEC axing 11 election day polling places in Wannon, due to ballooning early votes and predictions of a small number of ballots to be cast in those towns.

Both major parties have hinted that there could be a review of early polling after the election, with Treasurer Josh Frydenberg saying last week that the 2019 three-week pre-polling period "does feel a bit long".

Meanwhile, more than 700 electoral officials will staff Wannon's polling places on election day, most of them hailing from the electorate.

Votes will be counted at the electorate's polling places on Saturday night with House of Representatives votes then recounted and checked at the Warrnambool voting centre.
