Australian immigration officials are preparing for the arrival of another 100 asylum seekers as detention facilities at Christmas Island are stretched to breaking point.
The Federal Opposition says the arrival of three asylum seeker boats shows that suspending refugee applications for Sri Lankans and Afghans has not worked.
The ABC reports two more boats were intercepted on Sunday. Another carrying 27 people was detected on Monday morning off the Kimberley coast.
It was the 110th illegal entry boat to have entered Australian waters since the federal government softened its immigration policy in August 2008.
The government suspended processing for Afghan and Sri Lankan asylum seekers on Friday. They will have to wait up to six months to have their claims processed.
