CANBERRA, July 11 (Xinhua) — Australia's Prime Minister Malcolm Turnbull has on Monday returned to Canberra to decide on his cabinet ministers for the 45th Parliament, after he secured victory in the 2016 federal election over the weekend.

Turnbull proclaimed victory on Sunday afternoon, after Opposition Leader Bill Shorten called the Prime Minister to concede defeat after it was apparent Labor would not win enough seats to deny the Liberal-National Party coalition a victory at the polls.

However before Turnbull can be sworn into Parliament, he must decide on which ministers will take up cabinet positions, after three cabinet members were not re-elected at the election.

Turnbull said there would likely be "many new and younger faces" in the new-look coalition government, to be decided on over the next week.

"Regrettably, several ministers have not been returned and so there will be some changes," Turnbull said on Monday.

Also prior to the swearing in ceremony, Turnbull must negotiate a new coalition deal with Nationals leader Barnaby Joyce. The Nationals are expected to be in a better bargaining position for cabinet positions after they secured a higher than expected percentage of seats in the lower house at the election.

It's expected that Liberal and National MPs will meet in Canberra on July 18, and will be sworn in once Governer-General Peter Cosgrove returns from an official visit to France next week.

Meanwhile Labor's shadow Treasurer Chris Bowen has spoken to Australian Broadcasting Corporation (ABC radio on Monday, promising that his party will work closely with the government to pass key legislation through the lower house. He said Labor would display mature "leadership" for the good of the nation.

"There are lots of measures we are prepared to support and indeed the government, if they're prepared to work with us, would get very quick passage through the parliament," Bowen told the ABC.

"We will not be engaged in the sort of wrecking ball approach Tony Abbott took for three years, that consistent negativity."

"Where we can work with the government, where we can work with the other parties in the parliament we will. The Australian people are looking for that sort of leadership and Labor will provide it. "

Debate has continued to rage over the future prospect of implementing an online or electronic voting system for future election; counting continues in five seats which are determined too close to call.

Prime Minister Malcolm Turnbull said he has been "an advocate of electronic voting for a long time", while Labor Leader Bill Shorten has said it is unacceptable to not have a clear result in the election eight days after voters went to the polls.
