The government has announced that the capacity of the Christmas Island immigration detention centre is to be increased within weeks.
This morning, the government defended the transfer of a group of asylum seekers from Christmas Island to the mainland before their visas were finalised.
So far in 2010, 11 unauthorised boats have arrived in Australian waters.
Immigration Minister Chris Evans says the island had a capacity to hold 1800 detainees but the government was hoping to increase that to between 2220 and 2300 "within a couple of weeks".
"We're obviously feeling a bit of pressure there," the minister told Sky News on Monday.

"We've got larger numbers on the island but we've also been increasing the capacity."
Tents installed on the Indian Ocean island had wooden floors.
Extra donga-type accommodation was also on the way, the minister added.
Asked what would happen if the number of asylum seekers arriving on boats outstripped the capacity of the Christmas Island detention centre, Senator Evans said 500 beds from a Darwin detention centre could be used.
"That's the current plan. Obviously, there's a limit to what you can do on Christmas Island," he said.
The Opposition says it would consider utilising more Australian territory and setting up detention facilities in foreign countries to counter numbers of asylum seekers.
