The majority voted in favour of disagreeing with an amendment to the usual second reading motion, which is "that the bill be read a second time" - parliamentary jargon for agreeing with the main idea of the bill. Because the amendment was unsuccessful, the usual second reading motion will be left unchanged.
Note that amendments like this (that is, amendments to second reading motions) do not change the wording of the bill but are instead expressions of the will of the House.
Crossing the floor
Bonner MP Ross Vasta (Liberal) crossed the floor to vote "No" against the rest of his party, which voted "Yes."
Mistaken vote
During the vote, Kooyong MP Monique Ryan inadvertently voted "Yes" to disagree with the amendment. She later made a mistake in correcting her voting record in the chamber, stating that:
During the second reading amendment moved by the member for Melbourne today, I cast my vote for the noes. This was not my intention. I wish to inform the House I intended to vote with the ayes. I thank the House.
Taken at face value, this would have reaffirmed that she was indeed voting "Yes" to disagree with the amendment. However, she clarified her actual stance on Twitter, which is to support the amendment by voting "No" against disagreeing with the amendment, writing that:
I should note: in the flurry of divisions this morning (among my first on the job!) I made a mistake, & my vote on @AdamBandt amendment was counted contrary to my intention.
As I’ve consistently stated: Australia must not open new coal mines, gas fields or fossil fuel projects.
The voting record below does not reflect this correction, as votes are, in most cases, final.
Amendment text
That all words after 'that' be omitted with a view to substituting the following words:
"whilst not declining to give the bill a second reading, the House acknowledges that for the Government to reach their target of Net Zero by 2050, not one new coal, oil or gas project can commence"
