'Big Spender' Cheung Tze-keung's widow, who wants to emigrate to Australia, has been refused even a travel visa. Law Yim-fong had been hoping to visit first to see whether Australia would be a suitable place to raise her two sons and avoid the publicity in Hong Kong, said Wong Wai-yee, who works for Ms Law's lawyer, Ivan Tang Yiu-wing. 'She wants a better environment for the kids to attend school,' Mr Wong said. 'They want to leave this sad place.' But he said Ms Law had recently been refused a tourist visa by the Australian Consulate. 'They didn't give her any reason,' Mr Wong said. A consulate spokesman declined to comment on specific applications, but said his Government reserved the right to deny visas to anyone not deemed to be of good character. The mainland trial and execution of Cheung in December brought Ms Law and her sons, aged three and seven, into the spotlight. Ms Law could not be contacted for comment. Mr Wong said she was also considering Canada, but did not know how that was progressing. 'We suspect she's been blacklisted by several countries because of [Cheung's] trial,' he said. Ms Law was charged in connection with the $167 million Guardforce robbery at Kai Tak in 1991, but was acquitted. Cheung was acquitted of involvement at a second trial.
