Australia should offer safe haven to up to 19,000 Hong Kong residents living in the community on visas, the Greens say, as they call on Scott Morrison to repeat Bob Hawke's historic response to the Tiananmen Square massacre three decades ago.

The Prime Minister has for weeks called for a solution to the ongoing crisis in Hong Kong, as the federal government grows increasingly concerned about the safety of 100,000 Australian dual citizens currently living the Chinese territory.

Chinese state media has condemned the violent pro-democracy protests, which have been ongoing for three months, warning on Monday that "the end is coming for those attempting to disrupt Hong Kong and antagonise China".

Greens leader Richard Di Natale told The Age and The Sydney Morning Herald the federal government should immediately offer permanent protection for anyone from Hong Kong who currently resides in Australia.
