Also, traps along the Yarra river https://www.google.com/maps/@-37.818863,144.9708563,51m/data...

Trust me, a lot of Australians hate the current leadership and would love to see them gone. Unfortunately we are tending towards the trial version of USA.
But didn’t the public just vote for coal?
The people I know who voted for the libs preferenced the greens first and only voted for the libs because labor would leave them financially worse off.

#34Wet garbage is extremely heavy and hard to clean up. These socks typically require heavy equipment to remove/maintain. These filters also only work well in very specific drain configurations. Not as effective as the article suggests.
I feel like a similar design could be implemented almost on any water way that is small enough, so I don't see how the drain configuration is a limitation.
They probably don't want to put them where there might be wildlife, so they would only want to put them in rainwater runoff.
This obviously isn't the answer to the entire plastic problem, but it seems to be helping.

I doubt that "Australia" Found a Way is putting credit where it deserves to go. It's not exactly a national priority.

#36I assume this can only work for outflows near a road in order to provide access to the machinery. Outflows in forests, and at the foot of cliffs might go uncaptured, but its a good stab at a solution.
In the Thames they have flotsam collectors that rubbish ends up as the tide tos and fros along the river, it's called a passive driftwood collector:

#37800 pounds in a couple of weeks... kind of dispells the notion that it's not coming from western countries.
800 pounds? China pumps 4,800,000,000 pounds (2.4 million tons) of plastic into the ocean each year. No, western countries are not perfect. Yes, the vast majority of ocean waste comes from poor, non-Western countries. The US, 3rd largest country by population, is #20 for ocean pollution. China alone produces 1/3 of all ocean waste. https://www.scientificamerican.com/article/world-s-oceans-cl...
Plastic waste per person is a different story.
https://ourworldindata.org/plastic-pollution
USA: 0.34kg per person per day
China: 0.12kg per person per day (just under a third of the US figure).
In cultural terms, China is already far ahead of the USA in terms of individual responsibility.

Edit: Though your point on the handling of waste itself still stands (at least according to 2010 figures)

#38> Though the installation and the manufacture of these nets cost money (about $10,000 each) That seems exceedingly expensive for a net and a metal ring to hold it (maybe because drainage outlets aren’t standard sizes?), but I’m impressed with the claims of how effective it is.
The city's website [1] says that cost includes the design, manufacture, install and associated civil works. [1] https://www.kwinana.wa.gov.au/our-city/news/Pages/City%E2%80...
Plus, it goes on to indicate that's a cost savings over the old "roam around and pick it up by hand" approach.

I would not call it individual responsibility. It’s called poverty.
Re: Nets on the outlets of drainage pipes save waterways from pollution
#40This seems worse in almost every respect than a hydrodynamic stormwater separator. With the latter, you pop open a manhole cover and suck out the goo with a vacuum truck. With a net, you have to somehow pick it up without spilling the contents. Then you hope you can empty it without destroying it or you replace it. This sounds much harder.
Oh, and hydrodynamic separators claim to catch oils, too.
