Australian PM Malcolm Turnbull

The Australian Prime Minister mocked his US counterpart in a speech Wednesday night to a gathered crowd of journalists and politicians, during the Australian Parliament's boozy annual Midwinter Ball.

In leaked audio aired by Australia's Channel Nine, Turnbull poked fun at his own efforts to ingratiate himself with the new US President during their meeting in New York.

It is their first encounter since an acrimonious phone call in February.

"We get along great. We have a fantastic relationship, I love Australia, I always have," the AFP news agency quoted Mr Trump as saying.

Protesters also gathered in Mr Trump's home city, the first time he has returned there since his inauguration.

Mr Trump said the two leaders had "reaffirmed ties" between their two countries, and discussed economic, trade, and national security co-operation, as well as migration issues.

Turnbull arrived on Friday evening for his official state visit to Australia’s former colony and largest aid recipient.

Yesterday, Turnbull visited the Isurava Memorial Site in Northern Province and Bomana War Cemetery in Port Moresby, to pay respect to former veterans who fought against the Japanese advancement towards Port Moresby in 1942.

Also, native Papua New Guineans were used as aids and carriers by Australians during the Kokoda Battle in World War II.

In a statement, PM Malcolm Turnbull said: “I will spend 7-9 April in Papua New Guinea and 9-12 April in New Delhi and Mumbai.

“During my time in PNG, I will meet with Prime Minister Peter O’Neill and visit the Kokoda Track to commemorate the 75th Anniversary of the New Guinea Campaign in World War Two.

“The visit is an opportunity to build upon our bilateral economic relationships in the Pacific, and will involve multiple business events, including a joint Australia-PNG Entrepreneur and Innovation Showcase.”

Prime Minister Malcolm Turnbull is set to discuss security with other leaders at the Asean summit in Laos.

Mr Turnbull has signalled he would like to expand Australia's counter-terrorism arrangements with Indonesia, Malaysia and other neighbouring countries.

It comes after the so-called Islamic State threatened "lone wolf" attacks in Sydney and Melbourne.

Mr Turnbull said that such a threat should be taken seriously after IS suffered losses on battlefields in Iraq and Syria.

Counting continued on Tuesday and the race remains too close to call.

Mr Turnbull said he remained confident he could get the seats necessary to form a majority government.

His office denied accusations made by opposition leader Bill Shorten that he planned to hold a snap election in the wake of an unclear result.

Australia faces the prospect of a "hung parliament" if neither of the two main parties reaches the 76-seat quota.

With almost 80% of the vote counted, 10 seats remain in doubt, according to the Australian Broadcasting Corp.'s (ABC) analysis.
