Opposition Australian member of parliament Scott Morrison will be visiting Malaysia on a fact-finding mission over the asylum-seeker swap deal, but will likely find little more than a lukewarm reception - if any - when he arrives.

This is because the Juia Gilliard administration has reportedly warned against Morrison raising criticisms of the controversial deal between Canberra and Putrajaya, which will see Australia sending 800 asylum-seekers here in exchange for 4,000 asylum-seekers from Malaysia over an extended period of time.

The Australian government is concerned the aim of the trip is to undermine negotiations between it and Malaysia on the refugee transfer agreement.

According to a report in the Sydney Morning Herald ( SMH ), Opposition spokesperson Scott Morrison will travel to Malaysia this week on a fact-finding trip paid for by his government and is slated to meet representatives of human rights groups organisations Amnesty International Malaysia and Lawyers for Liberty this Friday.

SMH said it is believed that premier Gilliard has warned Australia’s Opposition leader Tony Abbott “in writing that there is a convention for MPs travelling overseas to refrain from openly opposing government policy.”

Gillard had earlier told the Australian Parliament that the discussions between her government and Putrajaya “are in an advanced state”.

“I trust that when the shadow minister travels to Malaysia soon that he does not conduct himself in a manner that is inappropriate for a member of Parliament when overseas,'' SMH quoted her as saying.

Morrison reportedly highlighted in the Australian Parliament on Wednesday the nature of his fact-finding trip to Kuala Lumpur and had detailed "a list of complaints" against the Malaysia’s civilian volunteer corp Rela and its members’ treatment of refugees.

The disinclination by the Australian government towards his visit here is apparently shared by the Malaysian government, said SMH .

Up until the eve of Morrison’s visit, Malaysia has yet to inform the MP whether or not his requested meeting with Home Affairs Minister Hishammuddin Hussein, or any government officials, will be granted.

“High-level sources in Malaysia said they were not inclined to meet Mr Morrison because he was not an official government representative and the refugee deal was yet to be finalised,” said SMH .

“Fairfax Media has been told its foreign correspondent in the region was not invited to cover Mr Morrison's meetings, or any visits to refugee facilities, but may interview him at the end of his visit on Monday.”
