Is the referendum literally just to ask whether the constitution should recognise the First Peoples of Australia? Is there a good reason why the tally so far shows every state is voting no?

Is the referendum literally just to ask whether the constitution should recognise the First Peoples of Australia?

It was actually about whether the constitution should be changed to say there shall be a body called the Aboriginal and Torres Strait Islander Voice, and that this body "may make representations to the Parliament and the Executive Government of the Commonwealth on matters relating to Aboriginal and Torres Strait Islander peoples". Purely symbolic recognition would have had a much better chance of getting in IMO.

$2.50 used to be pretty standard a few years ago, i think ive seen $3.50 last election too. Onions are always included in a sausage sandwhich, but you can can choose to not have them (same price). They always ask. Sauce is usually free, itll be a table with tomato, BBQ and maybe mustard if its a fancy place you just squeeze on yourself

The referendum was on whether to create and enshrine an advisory body with the power to make indigenous-focused representations to parliament.

I suspect the referendum would have succeeded if it were purely to recognise Australia's aboriginal people as being the first peoples of Australia.
