SYDNEY, Australia (CNN) -- Australian Prime Minister John Howard is again sending military transport aircraft and a supply ship to Indonesia to help the earthquake relief effort there.
Two Hercules C-130 transports leave Sydney for Sumatra on Wednesday morning carrying medical supplies and a medical evacuation team. A third aircraft is on standby if needed.
A supply ship, HMAS Kanimbla, is being diverted from Singapore back to Indonesia to help with helicopter support operations. The Kanimbla, which has hospital facilities, was heavily involved in relief efforts after the December 26 earthquake and tsunami.
Australia has been a major contributor to relief efforts in Indonesia since December 26, and in January signed a Aust. $1 billion ($780 million) joint partnership agreement with Indonesia to rebuild the devastated province of Aceh.
Australian military personnel who have been working in Aceh on relief efforts there had only just begun returning to Australia at the start of this week.
Howard said he had offered medical facilities and emergency aid to Indonesian President Susilo Bambang Yudhoyono during a call to him on Tuesday.
Howard also said Yudhoyono was delaying his planned visit to Australia this week and would first visit the quake-devastated areas of Sumatra.
The Indonesian leader, who was due in Canberra on Wednesday, will now arrive in Australia in Sunday night for talks in Sydney and Canberra on Monday and Tuesday.
It will be Yudhoyono's first official visit to Australia since coming to power in October last year.
Australia and Indonesia have had prickly relations in the past, but ties have improved recently with the ascendancy of Yudhoyono and Canberra's speedy response to the December 26 tsunami tragedy.
