Hawaii will ban the sale of sunscreens containing oxybenzone and octinoxate, which have been found to be toxic to coral and algae. The ban would take effect in 2021, and wouldn't apply to prescription sunscreens, online purchases, or sunscreen brought from out of state.
Hawaii bans sunscreens with chemicals that damage coral reefs, but Australia reluctant to follow
But there is far less enthusiasm for a similar ban in Australia, with some experts questioning the evidence behind Hawaii's decision. [...] Hawaii's decision was partly based on a report from 2015.
[...] "It's still a matter of balancing our planet health with human health when we know that two out of three Australians will develop skin cancer in their lifetime," Cancer Council Australia CEO Sanchia Aranda said.
Professor Aranda said there was still no conclusive scientific evidence the chemicals caused coral bleaching. "If there was evidence for marine damage strongly and the TGA, who regulates sunscreen and the chemicals that go into sunscreen, believed that it was harmful, then we would also seek to support that," she said.
2015 study reported at UCF and NPR.
Toxicopathological Effects of the Sunscreen UV Filter, Oxybenzone (Benzophenone-3), on Coral Planulae and Cultured Primary Cells and Its Environmental Contamination in Hawaii and the U.S. Virgin Islands (DOI: 10.1007/s00244-015-0227-7) (DX)

Looks like there might be some clear evidence to warrant this action by Hawaii.

I can't see that evidence.
So? Bleach is toxic for human, but something similar is dropped in swimming pools every day. Everything depends on concentration. Is concentration of oxybenzone in the wild, near the coral reef, significant? That is the question. If the sum of use of sunscreens along the years has been like a drop of tea in a Olympic swimming pool then we are overreacting.
OK, it is toxic and should be replaced by other innocuous components. But if there is no immediate danger, banning right now, over the night, is a little... trying to be whiter than white.
It looks that nowadays overreacting is the new rule.

Someone wrote "let's destroy markets: Tourism, sunscreeners, retailers." I think that's an overreaction, because there are other ingredients that can be used in sunscreens, and there are sunscreens already on the market that use those other ingredients without octinoxate or oxybenzone. Some people were already avoiding the ingredients that Hawaii is banning.

Unfortunately, a single study is not very useful, especially nowadays. It is especially not conclusive. If the bar was merely to ban any product that a paper or two claimed was hazardous, no products would exist.

What? Your thought process is garbo. There are good and bad studies, but consider existence proofs.
Study quality varies. More studies aren't inherently better than fewer. More /study participants/ generally improve the strength of statistical conclusions.
Look at, for example, LD50 studies using lab strains of mice. Run one such study using data from a couple of labs and with a sufficient count of mice, and the results are tremendously useful.
You should be able to see the flaw in your thinking by examining the words "especially nowadays." What you really mean is, "there are bad studies," not "no individual study is good."

No, what I really mean is what I said: one study is not conclusive. Policy should not be made on the basis of a single study, no matter its quality. Coming to a conclusion cannot happen when only one group has put work into the subject; others must examine it as well. Any one study can be easily flawed in a way that goes unnoticed. The number of studies is important because it is a barometer for how many different groups have looked at the question from different angles.
And throwing out pejoratives doesn't make your case sound any more reasonable, either.
