The majority voted in favour of disagreeing with the amendment to the usual second reading motion "that the bill be read for a second time" (which is parliamentary jargon for agreeing with the main idea of the bill). This mean that the amendment failed.
This amendment was introduced by Watson MP Tony Burke (Labor) and, if it had been successful, its text would have been added to the usual second reading motion as a note. In other words, it didn't seek to change the actual text of the bills.
MP Burke explained the rationale behind his amendment in his contribution to the debate.
That the following words be added after paragraph (4):
"(5) calls on the Government to recognise that the Australian arts and entertainment sector needs a specific, tailored, fiscal response package to ensure its ongoing viability, given the structure of the JobKeeper payment has been designed in a way that leaves many workers in the sector ineligible".
