FACT: The 457 visa was abolished by the Turnbull government in 2017. The visa which replaced it - the Temporary Skill Shortage Visa - is restricted to areas where there are critical skills shortages. Mandatory labour market testing must be done before the visas can be applied for. There are also training obligations in place to ensure employers train workers in the areas of skills shortages.

CLAIM: The "vast majority" of Australians want Muslim immigration cut.

FACT: According to a regular, large-scale survey of attitudes to migration run by Monash University, about 80 per cent of Australians support a non-discriminatory immigration program. In 2017, just 15.8 per cent of respondents said it should be possible to reject migrants based on their race or ethnicity. Although the survey found negative sentiment toward Muslims was "relatively high", the figure did not exceed 25 per cent. (Source: Scanlon Foundation's Mapping Social Cohesion study).
