At least 8,000 Sri Lankan nationals, including refugees from camps in India, reached Australia since May 2009.
A source in the Australian immigration department told Times of India that 8,170 Lankans arrived in Australia between May 2009 and April 10th, 2013.
Statistics show that the influx of Sri Lankans increased after the end of the war.
While only 16 people arrived in Australia in 2008, the year 2012 saw the highest number of 6,428 asylum seekers.
Only about 1,000 Lankan migrants, both Tamils and Sinhalese, have been issued settlement visas so far.
