There remains no indication that Bill will pass as it does not have support of the key opposition party (Australian Labor), nor any of the 'crossbenchers' (minor parties and independents).
That's party politics I guess. There are plenty of Labor pollies who would also be in favour of amending the Qantas Sale Act (IIRC some have even said so publicly in the past) but will fall in line just to frustrate/embarrass (take your pick depending on where you stand) the government .
