Australia stands ready to help Vietnam recover from the typhoon that struck Southeast Asia and added to the "significant burden and difficulty for our region", Foreign Minister Stephen Smith says.

Mr Smith said Australia was prepared to help Vietnam after earmarking $1 million for the Philippines in the wake of Typhoon Ketsana.

The death toll from the typhoon has risen to 383, after more casualties were confirmed in Vietnam and Cambodia on top of the estimated 277 deaths in The Philippines.

Mr Smith said the government also stood ready to provide further assistance to The Philippines after the country suffered its worst flooding in a decade.

More than two million people are either homeless or in urgent need of supplies in The Philippines, Vietnam, Cambodia and Laos.

"(The typhoon) crossed the coast of Vietnam late last week and over the weekend south of Danang," Mr Smith told reporters in Perth.

"We are seeing loss of life in Vietnam and also seeing adverse consequences in both Laos and Cambodia, including the loss of life in Laos.

"We are putting ourselves in a position of being able to respond to an expected request for assistance from the Vietnamese authorities.

"At this stage the level of devastation in Laos and Cambodia is such that the governments of those countries believe they can cater for the adverse consequences of the cyclone.

"That is a significant burden and difficulty for our region, and we're working very hard in conjunction with our friends and partners in the Pacific and in southeast Asia to render assistance."
