Labor's gambling deal rests on an opt-out register. Where opt-out already exists, fewer than one in a hundred people used it.
About 130,000 of SBS On Demand's 15 million accounts have switched betting ads off, and the new register has no start date.
The deal that gets Labor's gambling advertising bill through parliament is a register.
Australians who do not want betting ads online will put their details in one place, and the platforms will have to stop showing them.
Communications Minister Anika Wells called it a "one-stop shop".
A version of it is already running.
SBS became the first broadcaster in the world to let viewers switch gambling ads off on its streaming service, and it made the trial permanent this year.
The Senate inquiry into the bill was told what happened next.
Of roughly 15 million SBS On Demand accounts, about 130,000 have used it.
Fewer than one in a hundred.
Independent senator David Pocock put that number in his response to the inquiry and drew the obvious conclusion, which is that a right nobody finds is not much of a right.
The register is meant to answer exactly that.
One place instead of a setting buried in every separate app, and a levy on the betting companies to pay for it, the same way BetStop is funded.
The Australian Communications and Media Authority builds it, runs it and polices it.
ACMA told the inquiry it had not been given extra resourcing to do any of this.
The government has since said the regulator will get help.
There is no start date.
The government says the register will be complicated to build and could take a long time, and the rest of the changes are due to take effect on July 1 next year without it.
This is not the first register.
BetStop lets a gambler lock themselves out of every licensed Australian site for anything from three months to life.
A Sydney man signed up for a lifetime ban and lost close to $70,000 anyway.
The Greens say the overhaul is deliberately convoluted and doubt ACMA can run the thing at all.
Anthony Albanese has firmly rejected the alternative, which is making the ads opt-in.
Three years ago a parliamentary inquiry chaired by the late Peta Murphy handed down 31 recommendations and asked for gambling advertising to be phased out entirely over three years.
Ads that nobody sees do not need a register.
What is being built instead is a form, administered by a regulator that says it was not funded for it, paid for by the industry it switches off, with no date attached.
An opt-out is a tool for people who have already worked out the ads are a problem.
The ads are aimed at everyone who has not.
